🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and empty the glove box

• Open the glove box fully and remove any items.
• Use a flashlight to look along the right side for the glove box “damper” (a small arm that slows the glove box).

Step 2: Disconnect the glove box damper

• Use a small flat trim tool to gently pry the damper arm off its pin/clip on the glove box side. Go slow—don’t twist hard.
• Damper = the little arm that soft-opens the glove box.

Step 3: Release the glove box stops and lower the glove box

• With both hands, push the glove box sides inward to clear the built-in “stops.”
• Let the glove box rotate downward until it hangs open, giving access behind it.

Step 4: Remove the cabin filter cover

• Behind the glove box, locate the rectangular cabin filter door.
• Press the locking tabs and pull the cover off by hand (use the flashlight to see the tabs clearly).

Step 5: Remove the old cabin air filter

• Put on nitrile gloves and safety glasses.
• Slide the filter straight out. Keep it level so debris doesn’t fall into the housing.
• Tip: Vacuum nearby dust if needed.

Step 6: Install the new cabin air filter

• Check the airflow arrow on the new filter and match it to the direction marked on the housing/door.
• Slide the new filter in straight, without bending it.

Step 7: Reinstall the cover and glove box

• Reinstall the filter cover until the tabs click in place.
• Lift the glove box back up and push the sides inward again to pass the stops.
• Reconnect the damper arm (press it back onto its pin/clip by hand; use the small flat trim tool only if needed to guide it).

✅ After Repair

• Start your Telluride and run the blower on medium-high to confirm strong airflow.
• Switch between fresh air and recirculate to verify normal operation and no rattles from the glove box area.
• If you still have a musty smell, consider an A/C evaporator cleaner service next.
