The many common causes that hinders normal procedure of wait conditioning device on her Chevy Equinox are dirty cabin wait filter, refrigerant leak, dirty or clogged condenser, dirty or clogged evaporator, bad blower motor, defective compressor, faulty blend door actuator or any type of fault in the electrical system.

1. Dirty cabin wait filter

The pollen filter, likewise known as the cabin filter or microfilter, is a central component that the ventilation device in her Chevy Equinox. A dirty filter causes the in its entirety ventilation of the inner to damage resulting in diminished cooling, heating and also air flow. It also puts unnecessary stress, overload on the whole AC device which negatively effects your Equinox’s fuel consumption.

There is no prescribed time for changing cabin waiting filter, but most manufacturers recommend a adjust after 10,000-20,000 miles. If you journey your auto in dusty or polluted environment, the filter can acquire dirty much sooner than manufacturer’s recommendation.

Start by inspecting the condition of the cabin air filter on your Equinox. Instead of an altering it directly, that is often recommended to very first clean the pollen filter. This have the right to be done, because that example, v a vacuum cleaner or a compressed air system, remove at the very least a big part that the visible dust particles. Unfortunately, this procedure does not permit you to gain into the deeper great of the filter. Therefore, the filter performance will not increase considerably even after cleaning. As a rule, there is no staying clear of a change.

You don’t necessarily need to visit a workshop come clean or replace the pollen filter on her Equinox. Friend can access the filter by adhering to a few simple steps, as displayed in the video.

Note: Dirty cabin air filter mainly only leader to diminished cooling. If only hot air comes the end of the air vents in her Equinox, climate the difficulty probably lies somewhere else.

2. Dirty or clogged condenser

Like the radiator, the air conditioning condenser top top Chevy Equinox sits at the prior of the vehicle and also is responsible because that releasing the warmth from the refrigerant into the approximately air. Over time, grime, bugs and other small particles can construct up on its surface and in the gaps the its mesh. This hinders the condenser’s capacity to release heat as less air passes through the mesh, which results in bad cooling in the interior.

If the condenser is dirty on her Equinox, the most basic solution is to clean it. For this you typically have to eliminate the prior bumper to gain accessibility to the condenser. You deserve to use strength washer because that cleaning, yet make certain that its in ~ low push setting, together high pressure can easily damage the delicate fins top top the condenser.


A clogged or leaking condenser can also be the reason for air-conditioning no working effectively on your Equinox. A leaking condenser deserve to lead come a loss of refrigerant and reduced cooling performance of the system. In stimulate to discover leaks in the air air conditioning system, a leak find is lugged out in the workshop using developing gas – also the the smallest leaks have the right to be detected. In this way, it have the right to be identified whether the ns of refrigerant is because of a defective condenser. If this is the case, the only option is to change the broken part.

3. Refrigerant Leak

Insufficient lot of refrigerant is still the main cause of a non-functioning AC system. A loss of approximately 15% of the refrigerant per year is normal because of the design. If you don’t have actually the mechanism serviced frequently on your Equinox, the refrigerant level will eventually get so low that the system loses the cooling capacity. Just have actually it refilled and also you have the right to drive through pleasant temperatures again. If the refrigerant level goes down again quickly, climate it method there is most likely a leak.

In enhancement to the regular loss, ingredient defects space usually responsible for the escape of the refrigerant gas ~ above Chevy Equinox. A defective sealing ring, a worn heat or a condenser that has actually been damaged by a stone chip are the most usual causes.

Finding these mainly very tiny leaks is frequently not easy. The device is fill with forming gas (nitrogen with a little hydrogen) in the workshop. Larger leaks may already be heard or girlfriend can find them v a leak detection spray. Smaller sized holes have to be localized by browsing all components with a gas detector. As soon as the leak has actually been found, this need to be closeup of the door again by replacing the corresponding component.

4. Dirty evaporator

Dirty evaporator can likewise be the reason for AC problems on her Chevy Equinox. Cabin air filter records most that the dirt or various other airborne particles, yet some escape and fall on come the evaporator. End time, this dust particles have the right to builds increase on the fins and also block the air flow through the evaporator, result in bad cooling.


The 2 most significant symptoms that a clogged increase evaporator on your Equinox are:

The air flow from the vents is choppy and not smooth.The within of the car is arising a bad moldy smell.

Cleaning the evaporator on Equinox is not a straightforward task. In most cases, the whole dashboard has to be removed before you can accessibility the evaporator. As such it is encourage to carry out this at a workshop.

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

5. Compressor failure

The compressor is the love of the whole air conditioning device on Chevy Equinox. It is composed of moving parts that transform what is actually a gas coolant into liquid – this is how your car is cooled.


A damaged compressor is normally irreparable. If the air conditioning is switched on regularly, the parts additionally remain movable. However, if you don’t rotate on the air conditioning on her Equinox for a lengthy time, the components will stick. The an outcome is a defective compressor that can no much longer be repaired. The only thing the helps is swapping through a brand-new one.

The worst damage, however, is a failure of the AC compressor when it “eats” itself as result of insufficient lubrication or a production error, metal chips form, i beg your pardon are spread throughout the Equinox’s AC system. If you only install a brand-new compressor here, an additional failure is inevitable, together the chips instantly destroy the brand-new component. In such a case, virtually the entire air conditioning system needs to be replaced. A preferably of the metal pipes have the right to be rinsed here. Due to the fact that the two heat exchangers (condenser and also evaporator) space designed in cross-flow design, the laundry detergent finds the route with the the very least resistance and leaves the chips behind. However, the high-pressure refrigerant pulls this chips ago with it throughout operation and also the next damage is inevitable.

6. Poor blower motor

If there is no air circulation or decreased air circulation from the vents on her Chevy Equinox, poor blower motor could be the culprit. A worn out or dilute blower engine can also produce abnormal sounds once in operation.


You can not repair a damaged blower motor, the component must be replaced with a brand-new one.

Note: If the blower motor suddenly falls short from one 2nd to the next, friend must first check whether a puffy fuse is responsible because that the failure.

7. Faulty mix door actuator

Blend door actuator theatre a duty in managing the wait flow and temperature inside your Equinox. Anytime over there is a problem with the temperature the the air conditioning system, it could be a trouble with the blend door actuator.

The most usual symptom that faulty blend door actuator top top Chevy Equinox is a slight click sound consistently coming native under the dashboard. The sound will be most influential for a couple of seconds once you turn on the air conditioning or adjust the temperature. Sometimes transforming the temperature have the right to temporarily stop the sound.

A knocking noise can be another indicator the a bad blend door actuator on your Equinox, back its quite rare. The sound is something favor a irradiate tapping on the door and it happens when you rotate on the waiting conditioning mechanism or turn off the engine.


There are plenty of reasons why wait conditioning might not be working effectively on her Chevy Equinox. When trying to find the reason, girlfriend should constantly start through the most noticeable cause, low refrigerant level in the system.

In any case, that is advisable for laypersons come visit a workshop. In the event of a defect, the mechanic can straight initiate the repair.
