Does my 03 Sierra 1500 have a cabin air filter

[Deerassassin]

I went to auto zone and the said they have one. I've heard that they stopped in 03. Why would they sell a filter if there's not a spot for it. .

The following diagnosis might be helpful if the vehicle exhibits the
symptom(s) described in this PI.

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

Recommendation/Instructions:
Starting in the 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.

Please follow this diagnostic or repair process thoroughly and complete
each step. If the condition exhibited is resolved without completing
every step, the remaining steps do not need to be performed.
