The cabin air filter for a 2005 Chrysler 300 is located behind the glove box on the passenger side of the dash. Access the filter by lowering the glove box and removing the filter cover, then swap in a new filter with the arrows pointing in the direction of the HVAC airflow.
Location and access
In the 2005 Chrysler 300, the cabin air filter sits inside a rectangular black plastic housing mounted behind the glove box on the passenger side of the dash. To replace it, you’ll need to release the glove box stops or dampers, let the box drop down, and then open the filter housing cover to remove the old filter and install the new one.
What you’ll need
Gather a few common items before you begin to ensure a smooth replacement:
- Replacement cabin air filter compatible with a 2005 Chrysler 300 (OE or aftermarket)
- Flashlight (to see the housing clearly)
- Flathead screwdriver or small pry tool (optional, for releasing the filter housing tabs)
- Clean rag or cloth for wiping dust from the housing
Having these items on hand helps you complete the swap quickly and without unnecessary force.
Step-by-step replacement
Follow these steps to locate, remove, and replace the cabin air filter properly. The directions assume a standard passenger-side glove box setup typical of the 2005 300.
- Park the car, engine off, and set the parking brake. Open the passenger-side glove box and clear its contents.
- Gently press in on the sides of the glove box or squeeze the sides to release the dampers/stops, then let the glove box drop down to expose the filter housing behind it.
- Locate the rectangular cabin air filter housing and unclip or unscrew the cover by pressing the release tabs or pulling outward, as applicable.
- Remove the old filter from the housing. Note the orientation (arrow on the filter) to install the new one correctly.
- Clean the housing with a rag if you see dust or debris, then insert the new filter with the arrows pointing in the direction of the airflow (toward the HVAC unit/inside the car).
- Reattach the filter housing cover, ensuring it is firmly seated, then raise the glove box back into place and secure the stops/dampers.
- Close the glove box, start the car, and run the climate control on a few minutes to confirm air is flowing properly through the vents.
By following these steps, you’ll ensure the cabin air filter is correctly positioned and the HVAC system functions as intended.
Tips and maintenance
Regular replacement helps maintain air quality and HVAC performance. In dusty or urban environments, check and replace the cabin air filter more frequently—typically once a year or every 12,000–15,000 miles, whichever comes first. Use filters that match your vehicle’s specifications, and avoid forcing the cover if it doesn’t seat easily.
Summary
The cabin air filter on a 2005 Chrysler 300 is located behind the passenger-side glove box. Replacement involves lowering the glove box, removing the filter housing cover, swapping in a new filter with the airflow arrows toward the HVAC unit, and reseating the housing and glove box. With a bit of care, the process takes about 10–15 minutes and helps keep inside air clean and the climate-control system running efficiently.
