Yeah there is lol its under glove box I think every car/truck has it
Flex filter is / should be under driver door inline with fuel filter should throw a code when it needs it and my old flex fuel only turned on filter when I used e85

As cleveland63 stated there is no cabin filter. The fuel filter is not serviceable as it is part of the fuel pump. Despite what was posted above there are lots of vehicles without cabin filters. The serviceable fuel filter has become a thing of the past on most makes and models.

As for the A/C compressor behavior, it'll run when the HVAC controls are in the recirc, defog, or defrost mode unless it's freezing outside.

chevy pickups,tahoes,suburbans all stopped coming factory with cabin filters in 02 and suvs/passenger cars are hit and miss and although i disagree with it not many flex fuel vehicles have serviceable fuel filters

I mostly use the recirc mode to keep the dust and exhaust fumes out.
