A customer may inquire about the availability of the passenger compartment air filter.
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.
