2004 Silverado 1500: cabin filter..a 4.8 V8? It

This answer was rated:

How do I install a cabin filter in a 2004 Silverado 1500 4x4 WT with a 4.8 V8? It's reported to be a single, approximately 9.5"x 10.5" x 1" filter.

My truck does not appear to provide me with a visible site under the dash on the passenger side to unfasten a clip and swing a door aside as every guide depicts; but there is a compartment shape about this size observable end-on with no clear evidence of a door or even a seam in the plastic.

Hi, This vehicle does not have a factory installed Cabin Air Filter

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.
