Does this SUV have any cabin air filters

GM only lists an A/C refrigerant filter which is inline between the condenser and accumulator. In 2003 they took away the cabin air filter as an option. With the redesigned HVAC case, there is no longer a cavity for the filter. The GM parts catalog indicates there is replacement filter available; however there is no provision for it.

Here is a video of the job being done if your car has one as an option.

Hi,

In 1999, GM did not equip these vehicles with a cabin air filter. I will tell you that most newer vehicles are located on the passenger side of the vehicle and behind the glove box.

I hope this helps.

Take care,

Hi,

The original post is for a 2008 Suburban. Although these vehicles didn't come with a cabin air filter, one can be installed. Also, there is actually a technical service bulletin regarding how to install one.

Here are the directions. It will require a section of the air duct to be cut. The attached pics correlate with the directions.

This is for customer satisfaction; this is not a warranty procedure.

Condition/Concern

Some customers may comment that dust is intruding into the cabin interior. If the vehicle is driven primarily in high dust conditions, it may be possible for some residual dust to enter the cabin of the truck through the fresh air intake in the plenum, then through the HVAC case.

Recommendation/Instructions

At request of customer, install a cabin air filter following instructions below.

These vehicles did not come with a cabin air filter from the factory. First-time installation of the cabin air filter will require an installation kit. There are two different types of filter media offered; particulate or carbon/particulate. Refer to the part numbers listed in the Parts Information following the procedure below.
