The cabin air filter in a 2020 Dodge Ram is located behind the glove box on the passenger side, inside the HVAC housing. Accessing it requires lowering or removing the glove box to reach a rectangular filter carrier. This article explains where to find it and how to replace it.
For Ram trucks from the 2020 model year, including the 1500, 2500, and 3500, the filter helps clean air that enters the cabin through the HVAC system. Replacing it regularly can improve airflow and reduce odors. The following steps describe the typical access method and replacement process.
Location and access
In most 2020 Ram models, the cabin air filter sits behind the passenger-side glove box, within the HVAC housing. You’ll need to lower the glove box to expose a filter cover and the filter itself. Variations by trim exist, but the general access point remains the same.
What you’ll need
Before you begin, gather these items so you can complete the replacement without interruption.
- New cabin air filter compatible with your 2020 Ram (check the vehicle’s owner manual or parts store for the correct part number).
- Optional: flashlight for inspecting the housing and orientation arrows on the filter.
Having the correct filter size and type on hand makes the replacement faster and ensures a proper seal in the housing.
Steps to access and replace the filter
Use the following steps to locate, remove, and replace the cabin air filter. The process centers on lowering the glove box to access the filter housing.
- Park the vehicle, switch off the engine, and engage the parking brake to prevent movement while you work.
- Open the passenger-side glove box and let it hang down. On Ram models, you may need to gently press the sides to release the stops that hold the box in place.
- Locate the cabin air filter housing behind the glove box. Remove the cover by releasing the tabs or removing any small screws holding it to the housing.
- Take out the old filter and note the airflow direction indicated by arrows on the filter frame. If the housing is dirty, wipe it clean before installing the new filter.
- Install the new filter with the correct orientation, ensuring it sits fully inside the housing and the airflow arrows point in the proper direction (toward the cabin).
- Reattach the filter housing cover, then close and secure the glove box so it latches properly.
Reassembly complete. Start the engine and run the AC on a few minutes to confirm proper airflow. If the glove box doesn’t close smoothly, double-check that the housing and filter are seated correctly.
Notes and tips
Maintenance recommendations can vary by trim and whether the Ram uses a single- or dual-zone climate control. If your truck has a cabin air filter indicator, follow the manual’s reset steps after replacement. Always verify you have the correct filter part number for your exact configuration.
Summary
For a 2020 Dodge Ram, the cabin air filter is located behind the passenger-side glove box inside the HVAC housing. Access it by lowering or removing the glove box, unscrewing or uncliping the filter cover, and replacing the filter with the correct orientation. Regular replacement helps maintain air quality and HVAC performance.
