Where is the cabin air filter in a 2001 Pontiac grand am?

The 2001 Pontiac Grand Am cabin air filter is located behind the glove box. You'll need to remove or partially remove the glove box to access it. There's no single universal access method, as some Grand Ams might have slightly different glove box designs, but generally, it involves removing screws or clips holding the glove box in place. Consult your owner's manual for the most precise instructions specific to your vehicle's year and trim level.
