🔧 Grand Cherokee - Cabin Air Filter Replacement

On many Grand Cherokee models, the cabin air filter (if equipped) sits behind the glove box and filters dust/pollen before air comes through the vents. Some Grand Cherokee trims/years were built without a cabin filter from the factory—so the first step is a quick check for the filter access door.

Difficulty Level: Beginner | Estimated Time: 10-30 minutes

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Check if your Grand Cherokee has a cabin filter

• Use a flashlight to look under/behind the glove box area for a small rectangular HVAC access door (a removable cover on the air box).
• If you see an access door or a slot where a filter slides in, continue to Step 2.
• If you do not see any filter door/slot, skip to Step 6 (your A/C system may be built without a cabin filter).

Step 2: Lower the glove box

• Open the glove box.
• Use your hands (no tools) to gently push the glove box sides inward to clear the stoppers, then let it swing down.
• If a small damper strap is attached on the right side, use a plastic trim removal tool to carefully pop it off. Go slow—plastic gets brittle.

Step 3: Remove the cabin filter access door

• Use the flashlight to locate the access door on the HVAC housing behind the glove box.
• Release the cover tabs using your fingers; if tight, use a small flathead screwdriver to gently lift the tab while pulling the cover off.
• Set the cover aside where it won’t get stepped on.

Step 4: Remove the old cabin air filter

• Put on nitrile gloves and pull the filter straight out.
• Note the airflow direction arrow printed on the filter frame (this must match during install).

Step 5: Install the new cabin air filter

• Slide the new filter in the same direction as the old one, matching the airflow arrow.
• Reinstall the access door by pressing it in until the tabs click.
• Lift the glove box back up, reattach the damper strap (if removed), and push the glove box sides inward again to pass the stoppers and close normally.

Step 6: If no cabin filter is equipped (common on some builds)

• If you cannot find a filter access door/slot after lowering the glove box, your A/C system may be built without a cabin air filter.
• The only way to add one is with a cabin air filter retrofit kit that includes a door/holder (installation varies by kit).
• If you want, tell me whether you found a filter door/slot behind the glove box, and I’ll walk you through either the exact filter swap or the retrofit path.

✅ After Repair

• Start the engine and run the blower on all speeds to confirm good airflow and no rattles.
• Switch between fresh air and recirculation to confirm the airflow stays steady.
• If you smell musty odor, consider replacing the filter again sooner and checking for leaves/debris in the cowl area.
