• ⚠️ Empty the glove box first so items do not fall out when it swings down.
• ⚠️ No battery disconnect is required for this repair.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and Empty the Glove Box

• Use your hands to open the glove box fully.
• Remove all items from the glove box so nothing falls when it drops down.
• Use the flashlight to look along the right side of the glove box for the small damper arm.
• Tip: Take a quick photo first.

Step 2: Disconnect the Glove Box Damper

• Use your fingers to slide the glove box damper arm off its small peg on the right side of the glove box.
• If it feels tight, use the trim removal tool to gently help lift it off the peg.
• Do not pull hard; the damper is a small plastic slow-drop arm.

Step 3: Lower the Glove Box Past the Stops

• Use both hands to press inward on the left and right sides of the glove box.
• While pressing inward, slowly lower the glove box until the side stops clear the dashboard opening.
• Let the glove box hang down gently.
• No bolts are removed, so there are no torque specs for this step.
• Tip: Press evenly on both sides.

Step 4: Remove the Cabin Filter Cover

• Use the flashlight to locate the rectangular cabin air filter cover behind the glove box opening.
• Use your fingers to squeeze the tabs on the filter cover.
• Pull the cover straight out and set it aside.
• If a tab is stubborn, use the trim removal tool gently at the edge of the cover.

Step 5: Remove the Old Cabin Air Filter

• Use your fingers to pull the old cabin air filter straight out of the slot.
• Keep the filter level so dust and leaves do not spill into the blower housing.
• Look at the airflow arrow or orientation marking on the old filter before removing it completely.
• Tip: Match the arrow direction exactly.

Step 6: Clean the Filter Opening

• Use the flashlight to inspect inside the filter slot.
• Use your gloved fingers to remove leaves or large debris you can easily reach.
• Do not push debris deeper into the HVAC box.
• Do not run the blower motor with the filter removed.

Step 7: Install the New Cabin Air Filter

• Use your hands to slide the new cabin air filter into the slot.
• Install it with the airflow arrow facing the same direction as the original filter.
• Slide it in slowly so the pleats do not fold or crush.
• Make sure the filter sits flat and fully inside the housing.

Step 8: Reinstall the Filter Cover

• Use your hands to position the cabin filter cover over the opening.
• Press the cover in until the tabs click into place.
• Use the flashlight to confirm the cover is seated evenly on both sides.

Step 9: Raise and Reattach the Glove Box

• Use both hands to lift the glove box back toward the dashboard opening.
• Press inward on both sides of the glove box so the side stops pass back into place.
• Reconnect the damper arm onto the small peg on the right side by pushing it on with your fingers.
• Open and close the glove box once to confirm it moves smoothly.

Step 10: Test the HVAC System

• Use your hand to start the engine or turn the ignition to accessory mode.
• Turn the fan on low, then medium, then high using the climate controls.
• Listen for rattles, rubbing, or clicking sounds.
• If you hear noise, turn the system off and recheck that the filter is fully seated.
