🔧 Forte - Cabin Air Filter Replacement

Your A/C and heater pull air through the cabin air filter before it comes out of the vents. Replacing a dirty filter improves airflow, reduces odors, and helps keep dust/pollen out of the cabin.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and empty the glove box

• Open the glove box and remove anything inside so nothing falls out.
• Use a flashlight to look at the right side of the glove box for a small “damper” arm (a little slow-down strap that controls how the glove box drops).

Step 2: Disconnect the glove box damper arm

• Carefully pry the damper arm off its pin using a small flathead screwdriver or a trim removal tool.
• Tip: Pry gently—it's just a plastic clip.

Step 3: Release the glove box side stoppers

• On both sides of the glove box, there are built-in “stoppers” (plastic bumps) that prevent it from dropping all the way down.
• Push the glove box sides inward by hand to clear the stoppers, then let the glove box swing downward.
• Use work gloves to improve grip and protect your hands.

Step 4: Remove the cabin filter access door

• Behind the lowered glove box, locate the rectangular cabin filter cover.
• Press the tabs and remove the cover by hand; if it’s tight, use a trim removal tool to help start it.

Step 5: Remove the old cabin air filter

• Slide the old filter straight out.
• Keep it level so trapped leaves/dust don’t dump into the housing.
• Tip: Vacuum loose debris if needed.

Step 6: Install the new cabin air filter (correct direction)

• Check the airflow arrow on the filter frame.
• Install it in the same direction as the old filter. Most filters are marked AIR FLOW; typically it points down toward the blower fan in the housing.
• Slide the filter fully in so it sits flat and doesn’t buckle.

Step 7: Reinstall the cover and glove box

• Reinstall the cabin filter cover by hand until the tabs click.
• Lift the glove box back up and push the sides inward again to get past the stoppers.
• Reconnect the damper arm to its pin by hand; if needed, guide it with a small flathead screwdriver.

✅ After Repair

• Start the car and run the fan on high for 30 seconds.
• Confirm airflow is stronger and there are no rattles from the glove box area.
• If you hear fluttering, the filter may not be seated flat—recheck the cover and filter position.
