🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and empty the glove box

• Use your nitrile gloves and remove all items from the glove box so nothing falls into the dash.
• Use a flashlight to look along the right side of the glove box for a small “damper” arm (a little strap that slows the glove box).

Step 2: Disconnect the glove box damper (if equipped)

• Use the trim removal tool to gently pop the damper arm off its small peg on the glove box side. Gentle pressure beats prying hard.

Step 3: Drop the glove box down

• Use your hands (and a trim removal tool if needed) to press the glove box sides inward so the “stops” clear the dash opening.
• Let the glove box swing downward toward the floor so you can access the HVAC housing behind it.

Step 4: Locate the cabin filter access cover

• Use the flashlight to find a rectangular cover directly behind where the glove box was (it usually has small squeeze tabs).

Step 5: Remove the filter cover

• Use your nitrile gloves and squeeze the tabs on the cover, then pull the cover straight off.
• If the tabs are stubborn, use the trim removal tool to help gently—don’t snap them.

Step 6: Remove the old cabin air filter (if present)

• Use your nitrile gloves to slide the filter straight out.
• Use the flashlight and note the direction of the airflow arrow on the filter frame (you’ll match this on the new one).

Step 7: Install the new cabin air filter

• Use your nitrile gloves to slide the new filter in the same way the old one came out.
• Make sure the filter’s airflow arrow matches the housing direction. Wrong direction can reduce airflow.

Step 8: If there is NO filter slot (some base setups)

• Use the flashlight to confirm: you may see a blank panel or no usable filter track behind the cover area.
• In that case, use the parts from a cabin air filter retrofit kit (housing/door pieces) per the kit instructions, then install the cabin air filter.

Step 9: Reinstall the cover and glove box

• Use your nitrile gloves to reinstall the filter cover until it clicks.
• Lift the glove box back up, press the sides inward, and let the stops snap back into place.
• Reconnect the damper arm using the trim removal tool to guide it onto the peg if needed.

✅ After Repair
