Re: Aircon not working

Aircon isn't for making the car cold.
Aircon is for Air Conditioning.

It conditions the air, removing the damp by dehumidifying it. You can have aircon switched on, and have a warm/hot car if you want, and we frequently do.

Given the choice of hot weather and a cold car, or cold weather and a damp car, I would chose the latter. The benefits are huge.



Fiat AC not working &#; causes and how to fix it

The air conditioning is a blessing, especially in hot temperatures. Do you still sweat while driving your Fiat ? Your air conditioning system no longer cools properly? This can have different causes. What these are and what you can do about it, we explain in this article.

The most common causes that hinders normal operation of air conditioning system on your Fiat are dirty cabin air filter, refrigerant leak, dirty or clogged condenser, dirty or clogged evaporator, bad blower motor, defective compressor, faulty blend door actuator or any fault in the electrical system.

1. Dirty cabin air filter

The pollen filter, also known as the cabin filter or microfilter, is a central component of the ventilation system in your Fiat A dirty filter causes the overall ventilation of the interior to deteriorate resulting in reduced cooling, heating and air flow. It also puts unnecessary strain on the entire AC system which negatively impacts your &#;s fuel consumption.

There is no prescribed time for changing cabin air filter, but most manufacturers recommend a change after 10,, miles. If you drive your vehicle in dusty or polluted environment, the filter can get dirty much sooner than manufacturer&#;s recommendation.

Start by inspecting the condition of the cabin air filter on your Instead of changing it directly, it is often recommended to first clean the pollen filter. This can be done, for example, with a vacuum cleaner or a compressed air system, removing at least a large part of the visible dirt particles. Unfortunately, this procedure does not allow you to get into the deeper layers of the filter. Therefore, the filter performance will not increase significantly even after cleaning. As a rule, there is no avoiding a change.

Video: Replacing cabin air filter in Fiat

You don&#;t necessarily have to visit a workshop to clean or replace the pollen filter on your You can access the filter by following a few simple steps, as shown in the video.

Note: Dirty cabin air filter mostly only leads to reduced cooling. If only hot air comes out of the air vents in your , then the problem probably lies somewhere else.

2. Dirty or clogged condenser

Like the radiator, the air conditioning condenser on Fiat sits at the front of the vehicle and is responsible for releasing the heat from the refrigerant into the ambient air. Over time, grime, bugs and other small particles can build up on its surface and in the gaps of its mesh. This hinders the condenser&#;s ability to release heat as less air passes through the mesh, which results in poor cooling in the interior.

If the condenser is dirty on your , the simplest solution is to clean it. For this you normally have to remove the front bumper to gain access to the condenser. You can use power washer for cleaning, but make sure that its at low pressure setting, as high pressure can easily damage the delicate fins on the condenser.

A clogged or leaking condenser can also be the reason for air-conditioning not working properly on your A leaking condenser can lead to a loss of refrigerant and reduced cooling performance of the system. In order to find leaks in the air conditioning system, a leak search is carried out in the workshop using forming gas &#; even the smallest leaks can be detected. In this way, it can be determined whether the loss of refrigerant is due to a defective condenser. If this is the case, the only option is to replace the broken part.

3. Refrigerant Leak

Insufficient amount of refrigerant is still the main cause of a non-functioning AC system. A loss of up to 15% of the refrigerant per year is normal due to the design. If you don&#;t have the system serviced regularly on your , the refrigerant level will eventually get so low that the system loses its cooling capacity. Just have it refilled and you can drive with pleasant temperatures again. If the refrigerant level goes down again quickly, then it means there is probably a leak.

In addition to the normal loss, component defects are usually responsible for the escape of the refrigerant gas on Fiat A defective sealing ring, a worn line or a condenser that has been damaged by a stone chip are the most common causes.

Finding these mostly very small leaks is often not easy. The system is filled with forming gas (nitrogen with a little hydrogen) in the workshop. Larger leaks may already be heard or you can find them with a leak detection spray. Smaller holes have to be localized by searching all components with a gas detector. Once the leak has been found, this must be closed again by replacing the respective component.

4. Dirty evaporator

Dirty evaporator can also be the reason for AC problems on your Fiat Cabin air filter captures most of the dirt or other airborne particles, but some escape and fall on to the evaporator. Over time, these dust particles can builds up on the fins and block the air flow through the evaporator, resulting in poor cooling.

The two most prominent symptoms of a clogged up evaporator on your are:

  • The air flow from the vents is choppy and not smooth.
  • The inside of the vehicle is developing a bad moldy smell.

Cleaning the evaporator on is not a simple task. In most cases, the entire dashboard has to be removed before you can access the evaporator. Therefore it is recommended to do this at a workshop.

There can also be a refrigerant leak in the evaporator, in that case the evaporator will have to be replaced.

5. Compressor failure

The compressor is the heart of the entire air conditioning system on Fiat It consists of moving parts that convert what is actually a gaseous coolant into liquid &#; this is how your vehicle is cooled.

A broken compressor is usually irreparable. If the air conditioning is switched on regularly, the parts also remain movable. However, if you don&#;t turn on the air conditioning on your for a long time, the parts will stick. The result is a defective compressor that can no longer be repaired. The only thing that helps is swapping with a new one.

The worst damage, however, is a failure of the AC compressor when it “eats” itself due to insufficient lubrication or a production error, metal chips form, which are distributed throughout the &#;s AC system. If you only install a new compressor here, another failure is inevitable, as the chips immediately destroy the new component. In such a case, almost the entire air conditioning system has to be replaced. A maximum of the metal pipes can be rinsed here. Since the two heat exchangers (condenser and evaporator) are designed in cross-flow design, the detergent finds the path with the least resistance and leaves the chips behind. However, the high-pressure refrigerant pulls these chips back with it during operation and the next damage is inevitable.

6. Bad blower motor

If there is no air flow or reduced air flow from the vents on your Fiat , bad blower motor could be the culprit. A worn out or weakened blower motor can also produce abnormal sounds when in operation.

You cannot repair a broken blower motor, the part must be replaced with a new one.

Note: If the blower motor suddenly fails from one second to the next, you must first check whether a blown fuse is responsible for the failure.

7. Faulty blend door actuator

Blend door actuator plays a role in controlling the air flow and temperature inside your Anytime there is a problem with the temperature of the air conditioning system, it could be a problem with the blend door actuator.

The most common symptom of faulty blend door actuator on Fiat is a slight clicking sound repeatedly coming from under the dashboard. The sound will be most prominent for a few seconds when you turn on the air conditioning or adjust the temperature. Sometimes changing the temperature can temporarily stop the sound.

A knocking noise could be another indicator of a bad blend door actuator on your , although its quite rare. The sound is something like a light tapping on the door and it happens when you turn on the air conditioning system or turn off the engine.


There are many reasons why air conditioning may not be working properly on your Fiat When looking for the reason, you should always start with the most obvious cause, low refrigerant level in the system.

In any case, it is advisable for laypersons to visit a workshop. In the event of a defect, the mechanic can directly initiate the repair.

Fiat L A/C Repair Near You

Fiat L A/C Repair

Few things are worse than a broken car air conditioner on a hot summer day. Is that a hot stove? Nope, just your steering wheel. Your skin sticks to the driver’s seat. You wipe your brow and wonder, "Who can fix the A/C in my Fiat L?" Firestone Complete Auto Care can! We know Fiat vehicles, and our technicians are qualified to diagnose and repair Fiat L A/C systems. Come to your local Firestone Complete Auto Care in your Fiat L

During an A/C performance check, we'll determine the condition of your Fiat L A/C system to see if repair work is required. We’ll test overall system performance, check for any leaks, and measure the system pressure. If we suspect a leak, we’ll send a U/V dye through your A/C system or use a “sniffer” to find the leak. A "sniffer" is a machine that's run along parts of your Fiat L A/C system that can identify points where refrigerant fumes could be escaping the system. If your system has a leak, we can get it fixed.

Recharge the A/C in Your L

While your Fiat L’s air conditioner is being serviced, we’ll also do an A/C evacuation and recharge. To do this, one of our technicians will remove the refrigerant in your A/C system (if there is even any left to remove). Then, they’ll use Fiat’s specifications to evacuate the system. Finally, we’ll recharge the A/C system with new refrigerant and once the technician tests the cool blast for themselves, you’re all set. We want you to be comfortable in your car, so we train our technicians to perform Fiat L A/C recharges.

Common Fiat L A/C Problems

Warm air isn't the only Fiat L A/C problem you may encounter. Other common A/C problems include weak airflow, which could indicate an old ventilation fan, a seal or hose that needs replacing, or mold buildup in your A/C system. If you notice that your A/C system’s air is cold at first, then quickly goes warm, this may suggest a leak, a blown fuse, or a damaged compressor clutch. What about those (somewhat unpleasant!) smells coming through the A/C vents in your Fiat L? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. Our trained technicians will do what they can to solve your A/C problems. So, chill out. We're here to help you get the blast back in your L’s A/C!

Frequently Asked Questions for Fiat L A/C Systems

  • Can I make my L air conditioner colder? Park in the shade whenever you can, and use a reflective sunshade in the windshield when you’re parked. If you’re the only one in the car, close all the vents except the ones that point toward you. Give the system the final boost it needs with an A/C performance check and recharge from Firestone Complete Auto Care.

  • Why is my L A/C blowing hot air? If your car’s air conditioning isn’t blowing cold air at all (or it tries, then turns warm), you could have a clogged expansion valve, a faulty compressor clutch, a leak, or a malfunctioning fuse in the system.

  • What can cause an A/C system leak? To put it simply, age and moisture are some of the main causes of leaks in your A/C. Over time, rubber gaskets and seals can wear out, which pushes much-needed refrigerant out of your L’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.

My Fiat X air conditioning (A/C) is not working

The air conditioning have become one extremely fundamental element in all of our vehicles, maybe caused by the global warming or due to our interest for more significant aspect of coziness.

Consequently, you can be truly attached to this type of functionality in your Fiat X and simply can&#;t expect traveling not having it.

Although one day, the air conditioning begins to express several bad signals or more painful, fails to operate!

Let&#;s determine mutually the points which usually demonstrate this breakdown and simply how to repair the air conditioning of your vehicle.

Before we commence analyzing the solutions to fix the air conditioning of your car, understand that this component breaks down as comes after:

  • Compressor: This mechanical component put the refrigerant gas under pressure
  • Condenser: Located in front of the car, the condenser release the heat coming from the compressor
  • Evaporator: Located into the car, it provides fresh air to the driver and passengers
  • Thermal expansion valve: This component changes the hot hair into a fresh one
  • Drier/accumulator: These components are essential for the cleanliness of the air conditioning of your car

My Fiat X air conditioning is not working

Troubleshoot Air Conditioning of your Fiat X

The air conditioning (AC) of my car is leaking

The most familiar cause of an air conditioning issue with a car is refrigerant leakage. Generally there are two causes that often demonstrate this type of loss of refrigerant in your ac: the age of your car and the existence of mold.

One more vital element to detect a plausible leak: the existence of oil stain full of Freon, the compressed gas which specifically serves as power for the air conditioning of your car.

In the event you have any sort of doubt, consider taking your vehicle to the garage. The air conditioning of vehicles includes harmful items for your well being!

The air conditioning (AC) of my Fiat X smells bad

If it turns out your car&#;s air conditioning secretes rank odors, you most certainly have mold and various other organisms! If you suppose it&#;s no big deal, rethink it. Moreover to the bad scent, these kinds of microorganisms may be harmful to your body!

Often, only changing the air filter systems in your automobile&#;s interior will certainly erase the undesirable odor of the air conditioning

The air conditioning of my Fiat X is making noises

In case that your car makes a strange sound every time you activate air conditioning, you may be facing major issue. Frequently, a sound at this level shows that the air conditioning compressor will certainly soon be screwed and that you&#;re going to end up with no air conditioning in your car.

At the smallest suspect sound, move quickly to your auto technician who will definitely fix that for you!

It is now clear, presently there are different plausible causes for a malfunctioning air conditioning of your car. We would really like to tell you. Almost like battery replacement of your Fiat X , the air conditioning system as well comes with unhealthy products. Do not put your well being in peril for a car, it&#;s not necessary!

At least but not least, a free tip to you: do not let a problem of air conditioning hang. If you delay troubleshooting, your your Fiat X won t start, which is extremely more challenging!

Although air conditioning may not be a necessity to get from point A to point B, it sure contributes to the quality of the trip. If you find yourself in the less-than-ideal situation of driving a vehicle with non-functioning or under-performing AC, it serves you well to book a mechanic to fix it, so you can comfortably get through the heat.

How this system works:

At its most basic level, a vehicle’s air conditioning system works by intentionally manipulating the temperature and pressure of refrigerant and the direct relationship they have. The process begins with creating high-pressure gas by compressing the refrigerant inside your vehicle’s AC system to raise its pressure and temperature. The refrigerant then flows through the condenser, which turns it into a hot high-pressure liquid before going into the receiver. The receiver – sometimes referred to as a dryer – removes moisture and unwanted particles from the refrigerant. After that, it passes into the expansion valve, or orifice tube, which reduces the refrigerant’s pressure and causes the liquid refrigerant to change its physical state into a cold low-pressure gas.

To perform this change of state from liquid to gas, the refrigerant must have “latent heat,” and it must take that latent heat from the surrounding area inside the evaporator. As the latent heat is pulled from the evaporator core to almost below freezing, the blower motor sends the cold air through your vehicle’s vents. Think of a hot summer day, and you just got out of the pool: The liquid water on your skin starts to evaporate and turn into water vapor. The cooling of your skin is the result of the water pulling the latent heat away from your body to change its state into a vapor.

The air conditioning system is chiefly comprised of the following components:

  • Compressor: This is the core of your AC system. Powered by your vehicle’s serpentine belt, the compressor pressurizes the refrigerant. It is turned on and off by way of the compressor clutch.

  • Compressor clutch: Before the compressor turns on, a special electro-magnetic clutch called the compressor clutch is necessary to engage and disengage the compressor cycle. The compressor clutch tells the compressor when to turn on and off so the refrigerant is correctly pressurized for use by the condenser.

  • Condenser: Located in the front of the radiator, the condenser takes the hot refrigerant and cools it down while also reducing the pressure. This turns the refrigerant into a liquid that can pass to the next stage of the AC system.

  • Receiver/Dryer: Present in vehicles equipped with a thermal expansion valve, the receiver – or dryer – protects the compressor and other parts of the AC system from damage from unwanted particles and liquids. It separates gas from liquid (because the compressor can only handle gas), removes moisture by way of a desiccant, and discards contaminants.

  • Accumulator: Found in vehicles with an orifice tube, the accumulator has roughly the same function as a receiver. In fact, your A/C system will have either a receiver or accumulator – not both. In addition to filtering out debris and moisture, this part controls the amount of refrigerant that flows into the evaporator. The accumulator also stores excess refrigerant so that it cannot enter and damage the compressor. If you have an accumulator, then you don’t have a thermal expansion valve.

  • Thermal expansion valve or orifice tube: The thermal expansion valve and orifice tube have roughly the same function. In fact, your A/C system will have either an orifice tube or expansion valve – not both. Situated between the condenser and evaporator, either the expansion valve or orifice tube is responsible for regulating the amount of refrigerant that enters the evaporator, greatly reducing its pressure and temperature.

  • Evaporator: This component does the actual "cooling" in the vehicle. Set just behind your dash, the evaporator removes humidity from cabin air and cools the air that passes over it. A clutch cycling switch monitors and controls the temperature inside the evaporator’s core to prevent it from freezing, which can greatly damage your AC system as a whole.

  • Blower motor: This part moves the cool air that has passed over the evaporator through your vehicle’s vents. It is controlled by a central control head (or resistor) for fan speed. Also in the distribution system are a series of mode doors that control the direction of flow of cold air.

Note that all of these parts are universal for any vapor-cycle AC system, but the way the refrigerant is metered, controlled, and restricted will vary from manufacturer to manufacturer.

Common reasons for this to happen:

Although a malfunction in any part of your AC system can cause it to underperform or stop working altogether, there are certain issues that are common culprits. Low refrigerant is a common concern. However, since the refrigerant is recycled through the air conditioning system, the most likely way it can be lost is through a leak in one of the parts. Simply replacing the refrigerant will not solve the root of the problem.

The most frequent causes of a faulty air conditioning unit are:

  • Worn compressor: If your air conditioning suddenly stops working or starts making strange noises, the compressor may need to be replaced. A faulty compressor can also cause oil or refrigerant leaks, which a qualified mechanic can detect with dyes or a special infrared sniffer that can identify chlorofluorocarbon (CFC)-based gases.

  • Broken condenser: When your air conditioner blows air but it’s not cool enough, this can indicate problems with the condenser, although issues with the electric cooling fan or fan clutch could also be responsible. Typically, road debris causes damage to the condenser’s cooling fins and passage tubes, while internal debris prevents proper condenser function by restricting the flow of refrigerant and increasing high-side pressure. All of these cases result in a diminished ability for the condenser to transfer heat.

  • Faulty blower motor or resistor: If the AC system makes noise when you turn it on, but doesn’t push air through your vents, or if the blower only operates at maximum speed, the blower motor or resistor may be responsible.

  • Damaged receiver/dryer: If, in addition to your air conditioner not blowing cold air, moisture is accumulating on your windows that isn’t resolved by defrosting, the receiver is likely in need of replacement. This should be done as soon as possible because an excess of moisture will quickly damage other AC system components. 

  • Blown fuse: Sometimes, the simplest thing to fix can wreak the most havoc. So, it’s wise to check the fuse that controls your air conditioning before assuming the worst. However, simply replacing the fuse without exploring other symptoms can mask the root problem and cause further damage. If you find a blown fuse, take your car in. The mechanic working on your car may need to perform electrical tests to find the high resistance in the circuit and solve the problem that resulted in the blown fuse.

With that said, air conditioning problems can be summarized within 4 basic categories:

  • Hydraulic problems under the hood, such as a lack of refrigerant, too much refrigerant, a lack of adequate compression, or a lack of a refrigerant control device.

  • Electric problems under the hood, such as with the AC clutch coil, clutch relay, high-pressure cut-off switch, low-pressure cut-off switch, or circuit protection device.

  • Electrical problems in the dash, such as the AC switch not working, the computer control head or module going bad, or issues with the blend door command motor.

  • Mechanical problems in the dash, such as the blend door being physically broken, which prevents it from forcing air across the evaporator; the mode door being broken, which prevents it from forcing air though the vents; or the recirculation door being broken and falling into blower motor.

What to expect:

A top-rated mobile mechanic will come to your home or office to determine the source and cause of the AC malfunction. After the inspection, the mechanic will provide a detailed report that describes the air conditioning issue, along with the scope and cost of the necessary repairs.

How it's done:

The mechanic will perform a visual inspection of the air conditioning system, check the refrigerant for the proper charge, use a sniffer to identify any leaks of CFC gas, test the heater controls to make sure the air is being directed across the evaporator and sealing off the heater core, and then check other system components as specific symptoms and issues are identified.

How important is this service?

Air conditioning systems use extremely high pressures and temperatures. If any of the above symptoms happen, please do the safe thing: have your system inspected by one of our expert mechanics.

One of the most inconvenient vehicular problems is when the A/C won&#;t blow cold air.  If your Fiat isn&#;t keeping you cool, we&#;ve outlined some of the most common reasons why this might be happening.

The only thing that the air conditioning system has in common with the heater is that they both use the climate controls and the blower motor.  It is entirely possible for your &#;s heater to work just fine even when the air conditioner is not blowing cold at all.  That&#;s why troubleshooting the air conditioner is totally different than troubleshooting the heater.


Fiat Air Conditioning Not Blowing Cold Causes

Not Blowing Cold Air Fiat

  • Lack of Refrigerant&#;  Your &#;s air conditioner will not work if the refrigerant has disappeared due to a leak.  In fact, most won&#;t even cycle on without the right amount of refrigerant pressure.  This is far and away the most common reason that your &#;s air conditioner is not functioning.  It can be tempting to just get more coolant and get back on the road, but unless you find where the leak is coming from it&#;ll eventually happen again.
  • Bad Condenser&#;  If your condenser has taken damage or been clogged up, the coolant can&#;t transform the 
  • Clutch Cycling Switch&#;  A/C systems use an electromagnetic clutch to activate the compressor.  When this switch fails your air conditioning is dead in the water.
  • Blower Motor&#;  If there is no air blowing from your at all, the blower motor is at fault.  They are not that expensive and are easy to replace (most of the time).
  • Blend Door&#;  The blend door controls how much air conditioned and heated air enters the cabin.  If it gets jammed or locks up, your can&#;t respond to your temperature change request.

These are a few of the most common issues that could cause your to not blow cold enough.  There are other issues that can cause this as well.


Conclusion:  A/C Not Blowing Cold Fiat

Most of the time, when your &#;s air isn&#;t blowing cold enough, it is going to be a lack of refrigerant causing the problem.  We recommend having a professional recharge your A/C if it does end up being a coolant issue.  If you put too much coolant into the system, you can really do some damage.
