🔧 ProMaster - Cabin Air Filter Replacement

Difficulty Level: Beginner | Estimated Time: 10-20 minutes

Assumption: Your ProMaster is equipped with a cabin filter access door behind the glove box.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Empty and open the glove box

• Open the glove box and remove anything inside so it doesn’t fall out.
• Use a flashlight to look behind/under the glove box area.

Step 2: Lower/remove the glove box (if needed)

• If the glove box has side stops, gently push the glove box sides inward by hand so it can swing down farther.
• If a trim panel is in the way, carefully pry it with a trim removal tool (plastic).
• Go slow—plastic clips release with steady pressure.

Step 3: Locate the cabin filter access door

• Use a flashlight to find a small rectangular access cover behind the glove box (HVAC housing area).
• The cover typically has locking tabs on the sides.

Step 4: Remove the filter cover

• Use your fingers or a trim removal tool (plastic) to press the locking tabs and pull the cover off.
• Set the cover aside where it won’t get stepped on.

Step 5: Remove the old cabin air filter

• Put on nitrile gloves and pull the filter straight out.
• If it’s packed with leaves, pull it out slowly to avoid dumping debris into the blower housing.

Step 6: Install the new cabin air filter

• Check the airflow direction arrow on the filter frame.
• Install the new filter in the same direction as the old one came out (match the arrow).
• Slide it fully into place—don’t bend or crush it.

Step 7: Reinstall the cover and glove box

• Reinstall the access cover by hand until it clicks into place.
• Lift the glove box back up and re-engage the side stops (push sides inward again if needed).
• If you removed any trim, press it back in by hand until clips snap in.

✅ After Repair

• Start the engine and run the blower on all speeds to confirm strong airflow and no rattles.
