The cabin air filter in a 2021 Jeep Grand Cherokee is located behind the glove box on the passenger side. Access requires lowering the glove box and removing an access panel to replace the filter.
Location and access
In the 2021 Grand Cherokee (WK2), the filter sits in a rectangular housing on the passenger side, behind the glove box. To reach it, you’ll drop the glove box by releasing its stops or damper, which exposes the filter housing.
How to replace the cabin air filter
Follow these steps to access and replace the cabin air filter in your Grand Cherokee:
- Park the vehicle, turn off the engine, and engage the parking brake.
- Open the glove box and remove its contents.
- Gently squeeze the sides of the glove box to release the stops and lower the box fully.
- Look for the rectangular filter housing panel at the back of the glove box area and remove the cover or clips.
- Take out the old cabin air filter and note the airflow direction indicated on the filter frame.
- Insert a new filter, aligning it so the arrows point in the direction of airflow through the system (from outside air toward the blower).
- Reattach the housing cover or clips, ensuring it is securely fastened.
- Lift the glove box back into place and restore its damper/ends so it stops correctly.
After replacing, test the climate control to ensure air flows normally from the vents and there are no unusual noises from the glove box area.
Maintenance tips
To keep the HVAC system operating efficiently, replace the cabin air filter roughly every 12,000–15,000 miles or once a year, whichever comes first, and more often in dusty or polluted environments. If you notice reduced airflow, unusual odors, or increased cabin noise, inspect or replace the filter sooner.
Summary
In a 2021 Jeep Grand Cherokee, the cabin filter is located behind the passenger-side glove box. Replacing it involves dropping the glove box, removing the filter housing cover, and installing a new filter with the correct airflow orientation, then reassembling. Regular replacement helps maintain interior air quality and HVAC performance.
