Condition/Concern:
A customer may inquire about the availability of the passenger compartment air filter.

Recommendation/Instructions:
Starting in 2003 model year, the passenger compartment air filter is no longer available as a factory option. With the redesigned HVAC case, there is no longer a cavity for the filter. The GM parts catalog indicates there is a replacement filter available; however, there is no provision for it.

Hi there ,

GM stopped using cabin air filters in 2003 and up. I attached a warranty article from GM below.

However, here is a video to show you how to do the filters if your truck is so equipped.
