🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and support the glove box

• Open the glove box all the way.
• Use a flashlight to look at both sides of the glove box for the stops (small plastic “ears” that keep it from dropping).

Step 2: Release the glove box stops

• Press the glove box sides inward by hand to clear the stops, then let the glove box swing downward.
• If a side panel or small retainer blocks access, gently pry it using a plastic trim tool set. (A trim tool is a plastic pry tool that helps prevent scratches.)

Step 3: Disconnect the glove box damper (if equipped)

• On the right side, you may see a small “damper” arm (a little shock/strap that slows the glove box).
• Pop it off its pin using your fingers or a plastic trim tool set.

Step 4: Remove the cabin filter access door

• Behind the lowered glove box, find the rectangular cabin filter housing.
• Press the tabs and remove the cover by hand.
• If a screw is present on the cover, remove it with a Phillips #2 screwdriver.

Step 5: Remove the old cabin air filter

• Slide the filter straight out.
• Keep it level to avoid dumping debris.
• Note how the old filter is oriented before pulling it out.

Step 6: Install the new cabin air filter

• Check the airflow arrow on the filter frame.
• Install it in the same direction as the old one (typically the arrow points down toward the blower, but match what you removed).
• Slide it in without forcing it; it should seat smoothly.

Step 7: Reassemble the glove box

• Reinstall the housing cover until the tabs click (or tighten the screw with a Phillips #2 screwdriver if equipped).
• Reconnect the damper arm (if equipped) by pressing it back onto its pin.
• Lift the glove box and press the sides inward again to pass the stops back into place.
• Close the glove box and reinstall everything you removed.
