🔧 GS - Cabin Air Filter Replacement

Your GS cabin air filter cleans the air coming through the HVAC system (heat/AC), catching dust, pollen, and debris. Replacing it helps airflow, reduces musty odors, and keeps the blower motor from working harder than it needs to.

Difficulty Level: Beginner | Estimated Time: 0.25-0.5 hours

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Empty and open the glove box

• Open the glove box and remove any items so nothing falls behind the dash.
• Use a small flashlight to locate the glove box side “damper” (a small arm that slows the glove box as it opens) on the right side.

Step 2: Disconnect the glove box damper

• Use a plastic trim removal tool (specialty) to gently pop the damper arm off its pin/clip on the glove box side.
• Work slowly—light pressure is enough.
• Damper definition: a small arm that prevents the glove box from dropping fast.

Step 3: Drop the glove box down

• With the glove box open, press in on both glove box side walls (near the back) with your hands to clear the stops.
• Let the glove box swing downward gently.
• Use nitrile gloves to keep dust off your hands.

Step 4: Remove the cabin filter access door

• Behind the glove box, find the rectangular cabin filter housing.
• Use the plastic trim removal tool (specialty) to help release the tabs, then remove the access door by hand.

Step 5: Remove the old filter and note airflow direction

• Slide the old cabin filter straight out by hand.
• Look for the airflow arrow on the old filter’s frame (often marked “UP” or “AIR FLOW”).
• Use the small flashlight to check for leaves/debris in the housing and remove loose debris by hand.

Step 6: Install the new cabin filter

• Install the new filter in the same orientation as the old one (match the arrow direction).
• Make sure it seats fully and sits flat—no curling or folding.

Step 7: Reinstall the access door and glove box

• Reinstall the filter access door by hand until the tabs click in place.
• Lift the glove box back up and press the sides inward again so the stops pass into place.
• Reconnect the damper arm using the plastic trim removal tool (specialty) to guide it onto the pin/clip.
