In brief, the cabin air filter sits behind the glove box on the passenger side, inside a rectangular housing that you access by lowering the glove box and removing a small panel. You’ll typically replace it about every 15,000 miles or once a year, depending on driving conditions and climate, per the owner’s manual.
More detail: The Telluride’s cabin air filtration system pulls outside air through a filter located behind the passenger-side glove box. Access usually requires releasing the glove box stops and damper to drop the box, then removing the filter housing cover to reach the filter. Replace with a filter that matches your model year, orienting it so the arrows point in the direction of airflow into the HVAC system.
Location and access
What you’ll need
Before you start, know that the filter is behind the glove box on the passenger side. Typically no tools are required beyond your replacement filter; have the correct size on hand before you begin.
- Open the glove box and remove its contents.
- Squeeze the sides of the glove box to release the upper stops and allow the box to drop down, using the damper on the right to control the movement.
- Find the rectangular cabin air filter housing behind the glove box and remove the housing cover or panel.
- Slide out the old filter and inspect the area for debris or mold.
With the old filter removed, you’re ready to install the new one and finish the reassembly.
Replacement steps in detail
Install and reassemble
Make sure you have the correct replacement filter for your Telluride model year. Check the part number or size on the packaging and compare it to your vehicle’s specification before installation.
- Insert the new filter into the housing with the airflow arrows pointing toward the HVAC unit (as indicated on the filter).
- Reattach the housing cover or panel, ensuring all clips or tabs snap securely into place.
- Raise the glove box back into position and reengage the stops so the box sits flush; verify the damper re-engages properly.
- Return contents to the glove box and run the HVAC on fresh air to confirm even airflow and that there are no odors.
After replacement, recheck that the glove box opens and closes smoothly and that the HVAC system is drawing air normally from the vents.
