The cabin air filter is located behind the glove box on the passenger side, inside the HVAC housing. Access is gained by lowering the glove box, releasing a damper, and removing the filter cover to replace the filter.
Location and access
The following steps describe how to locate the filter, open the housing, and swap in a new filter with minimal tools. In most 2012 Avengers, the filter sits in a rectangular slot at the far end of the passenger-side HVAC plenum.
- Open the glove box and let it drop down. You may need to press inward on the sides to free the stops.
- Look toward the right-hand side of the glove box cavity for a small rectangular access door or cover on the HVAC housing.
- Release or remove the cover; some models use a couple of clips or screws to secure it.
- Gently pull out the old cabin air filter, noting the orientation of the cardboard frame and any airflow arrows.
- Insert the new filter with the arrows pointing toward the cabin air intake (same orientation as the old one). Reattach the cover and secure any clips or screws.
With the new filter in place, close the glove box and ensure it latches. If there was a damper on the glove box, reattach it as needed.
