AC filter

Removal
Locate the air filter door on the bottom of the lower evaporator housing just outboard of the passenger side of the instrument panel center stack. See Fig. 1.
Slide the air filter door latch toward the rear of the vehicle until it engages the opened stop on the door.
Pull the air filter door straight downward to disengage it from the air filter opening of the lower HVAC housing.
Use your fingers to reach through the air filter opening of the HVAC housing far enough to grasp the air filter.
Pull the air filter straight down and out of the HVAC housing and remove it from the vehicle.
