The many prevalent reasons that hinders normal procedure of air conditioning device on your Chevy Malibu are dirty cabin air filter, refrigerant leak, dirty or clogged condenser, dirty or clogged evaporator, poor breduced motor, defective compressor, faulty blend door actuator or any fault in the electric system.

1. Dirty cabin air filter

The pollen filter, likewise well-known as the cabin filter or microfilter, is a main component of the ventilation system in your Chevy Malibu. A dirty filter reasons the as a whole ventilation of the internal to deteriorate bring about reduced cooling, heating and also air circulation. It likewise puts unessential strain on the entire AC device which negatively results your Malibu’s fuel consumption.

Tbelow is no prescribed time for altering cabin air filter, however the majority of manufacturers recommfinish a readjust after 10,000-20,000 miles. If you drive your automobile in dusty or polluted atmosphere, the filter deserve to obtain dirty much sooner than manufacturer’s recommendation.

Start by inspecting the problem of the cabin air filter on your Malibu. Instead of transforming it directly, it is often recommfinished to first clean the pollen filter. This have the right to be done, for instance, via a vacuum cleaner or a compressed air device, rerelocating at least a large component of the visible dirt pwrite-ups. Unfortunately, this procedure does not allow you to obtain into the deeper layers of the filter. Because of this, the filter performance will not rise significantly also after cleaning. As a preeminence, tright here is no avoiding a readjust.

You don’t necessarily need to visit a workshop to clean or relocation the pollen filter on your Malibu. You deserve to access the filter by adhering to a couple of simple actions, as presented in the video.

Note: Dirty cabin air filter largely only leads to lessened cooling. If just warm air comes out of the air vents in your Malibu, then the difficulty more than likely lies elsewhere.

2. Dirty or clogged condenser

Like the radiator, the air conditioning condenser on Chevy Malibu sits at the front of the car and is responsible for releasing the heat from the refrigerant into the ambient air. With time, grime, bugs and also other small pshort articles have the right to construct up on its surchallenge and in the gaps of its mesh. This hinders the condenser’s ability to release warm as less air passes with the mesh, which outcomes in negative cooling in the internal.

If the condenser is dirty on your Malibu, the most basic solution is to clean it. For this you commonly have to rerelocate the front bumper to gain accessibility to the condenser. You have the right to use power washer for cleaning, however make sure that its at low press establishing, as high press deserve to quickly damage the delicate fins on the condenser.


A clogged or leaking condenser can additionally be the reason for air-conditioning not working correctly on your Malibu. A leaking condenser can cause a loss of refrigerant and also decreased cooling performance of the device. In order to find leaks in the air conditioning system, a leak search is carried out in the workshop utilizing forming gas – also the smallest leaks can be detected. In this means, it can be figured out whether the loss of refrigerant is due to a defective condenser. If this is the instance, the just option is to replace the damaged component.

3. Refrigerant Leak

Inenough amount of refrigerant is still the primary reason of a non-functioning AC mechanism. A loss of as much as 15% of the refrigerant per year is normal because of the architecture. If you don’t have actually the mechanism serviced regularly on your Malibu, the refrigerant level will certainly inevitably obtain so low that the system loses its cooling capacity. Just have actually it refilled and also you have the right to drive with pleasant temperatures again. If the refrigerant level goes dvery own aacquire easily, then it means there is most likely a leak.

In addition to the normal loss, component defects are normally responsible for the escape of the refrigerant gas on Chevy Malibu. A defective sealing ring, a worn line or a condenser that has actually been damaged by a stone chip are the the majority of widespread causes.

Finding these largely exceptionally small leaks is regularly not simple. The mechanism is filled via creating gas (nitrogen through a small hydrogen) in the workshop. Larger leaks might already be heard or you can uncover them via a leak detection spray. Smaller holes have to be localized by searching all components via a gas detector. Once the leak has been found, this have to be closed aobtain by replacing the respective component.

4. Dirty evaporator

Dirty evaporator have the right to additionally be the factor for AC troubles on your Chevy Malibu. Cabin air filter captures the majority of of the dirt or other airborne pwrite-ups, however some escape and loss on to the evaporator. Gradually, these dust pshort articles can builds up on the fins and also block the air circulation through the evaporator, bring about negative cooling.


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

The air circulation from the vents is choppy and not smooth.The inside of the car is emerging a poor moldy smell.

Cleaning the evaporator on Malibu is not an easy task. In many situations, the entire dashboard has to be removed prior to you deserve to accessibility the evaporator. Thus it is recommfinished to do this at a workshop.

Tright here can likewise be a refrigerant leak in the evaporator, in that situation the evaporator will certainly need to be reinserted.

5. Compressor failure

The compressor is the heart of the whole air conditioning device on Chevy Malibu. It is composed of relocating components that transform what is actually a gaseous coolant right into liquid – this is exactly how your vehicle is cooled.


A damaged compressor is generally irreparable. If the air conditioning is switched on consistently, the components likewise remajor movable. However before, if you don’t rotate on the air conditioning on your Malibu for a long time, the parts will stick. The result is a defective compressor that can no longer be repaired. The just point that helps is swapping with a brand-new one.

The worst damage, however, is a faitempt of the AC compressor as soon as it “eats” itself due to insufficient lubrication or a manufacturing error, metal chips form, which are distributed throughout the Malibu’s AC device. If you only install a new compressor here, another faiattract is unpreventable, as the chips automatically ruin the brand-new component. In such a instance, practically the whole air conditioning mechanism hregarding be reput. A maximum of the metal pipes deserve to be rinsed here. Due to the fact that the two warm exchangers (condenser and also evaporator) are designed in cross-circulation style, the detergent finds the route with the least resistance and leaves the chips behind. However before, the high-press refrigerant pulls these chips ago via it in the time of operation and also the following damage is inescapable.

6. Bad breduced motor

If tright here is no air flow or reduced air flow from the vents on your Chevy Malibu, negative blower motor can be the culprit. A worn out or weakened blower motor can also develop abnormal sounds once in operation.


You cannot repair a damaged blower motor, the part need to be reinserted with a new one.

Note: If the blower motor unexpectedly stops working from one second to the next, you must first check whether a blvery own fusage is responsible for the faiattract.

7. Faulty blfinish door actuator

Blfinish door actuator plays a duty in regulating the air circulation and temperature inside your Malibu. Anytime there is a trouble with the temperature of the air conditioning mechanism, it can be a trouble with the blfinish door actuator.

The the majority of widespread symptom of faulty blfinish door actuator on Chevy Malibu is a slight clicking sound consistently coming from under the dashboard. The sound will be the majority of prominent for a couple of secs when you revolve on the air conditioning or readjust the temperature. Sometimes changing the temperature can temporarily soptimal the sound.

A knocking noise might be another indicator of a bad blfinish door actuator on your Malibu, although its rather rare. The sound is somepoint favor a light tapping on the door and also it happens once you rotate on the air conditioning device or rotate off the engine.


Tright here are many kind of factors why air conditioning may not be functioning correctly on your Chevy Malibu. When looking for the reason, you have to constantly start through the a lot of obvious reason, low refrigerant level in the mechanism.
