Cabin Air Filter is Dirty
The cabin filter (microfilter or pollen filter), is an important part of the air conditioning system in a Chevy Traverse. When a filter gets dirty, the interior airflow in your Chevy Traverse will become less efficient, causing you to need to lower the cooling or heating systems or move less air. It puts a strain of unneeded energy on your AC system, which inevitably increases your cost of fuel.

How to Fix
Start by checking the cabin air filter in your Chevrolet Traverse. It is often more efficient to first clean the cabin air filter before you change the filter itself. You can do this by using a vacuum cleaner or a system that uses a lot of air to blow the dust away. This will allow you to get into the inner layers of the pollen filter and completely clean it. If the performance of filters does not improve much after the cleaning, then you need to change them.

Dirt-filled evaporators are sometimes the reason you find that you have no air conditioning in the cabin of a Chevy Traverse. Cabin filters catch most dirt and other air particles that are blown in from the outside, but some particles get away and fall onto the evaporator fins. Over the years, dust can collect on the fins of the evaporator and cause poor cooling. The most obvious signs that you have a clogged evaporator in your Chevrolet Traverse are:
- The vent airflow is choppy and not very consistent.
- The interior of your car has started to have a bad mould smell.
How to Fix
It is not easy to clean the evaporators on a car like a Traverse. In many cases, you will need to remove the whole dashboard to reach the evaporator. This requires you to go to a workshop to do this. A leak of refrigerating fluid in the evaporator can also cause the evaporator to fail. In that case, you need to replace the evaporator.
Refrigerant Leaks
Insufficiency in refrigerant can lead to a completely malfunctioning AC system. It is also typical that the system will lose up to 50% of its refrigerant every year. If you do not properly service the AC on your Chevrolet Traverse, the refrigerants in the unit will start to lose their cooling capacity. When the coolant level in your system goes down quickly, you are driving a very hot car. If there is a sudden drop in the refrigerants, it is likely that there is a leak.

Failure of a component or two may cause the refrigerant’s gas to escape from a Chevrolet Traverse. Most commonly, a faulty seal ring, squeaky lines that are rusted or a condenser that has been severely affected by a stone chip are the causes of this.
How to Fix
Sometimes it is very difficult to find leaks that are very small. In a workshop, they mix a chemical called nitrogen with a bit of hydrogen to form a gas. Large leaks can be easily detected by using a spray leak detector. Once a leak is found, it must be resolved again by either removing or repairing the defective component, or by putting a new one in place.
