đź“‹ Before You Begin
- 🔸 Park on level ground and shift to Park.
- 🔸 Turn the ignition OFF and remove the key/fob from the vehicle.
- 🔸 Open the passenger door for easier access to the glove box.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Empty and open the glove box
- Remove items from the glove box so nothing falls out.
- Use a flashlight to look along the right side of the glove box for the small “damper” arm (a little shock/strap that slows the glove box).
Step 2: Disconnect the glove box damper
- Use a plastic trim removal tool (specialty) to gently pop the damper arm off its pin (don’t pry hard).
- Damper = the small arm that soft-opens the glove box.
Step 3: Drop the glove box down farther
- Using both hands, press the left and right sides of the glove box inward to clear the “stops.”
- Let the glove box swing down toward the floor for access behind it.
Step 4: Remove the cabin filter access cover
- Behind the glove box you’ll see a rectangular cover for the filter housing.
- Squeeze the tabs and remove the cover by hand; if tight, use the plastic trim removal tool (specialty) gently.
Step 5: Remove the old cabin air filter
- Pull the filter tray/old filter straight out by hand.
- Keep it level to avoid dumping leaves/debris inside the housing.
Step 6: Install the new cabin air filter (correct direction)
- Check the airflow arrow printed on the filter.
- Install it the same way the old one came out—on your Odyssey it typically goes with the arrow pointing DOWN (toward the floor), but always match the arrow direction to the markings on the housing or the old filter.
- Wrong direction can reduce airflow.
Step 7: Reassemble the glove box
- Reinstall the filter access cover until the tabs click in.
- Lift the glove box back up, press the sides inward again, and set it back past the stops.
- Reconnect the damper arm by pressing it back onto its pin by hand (use the flashlight to line it up).
âś… After Repair
- 🔸 Start your Odyssey and run the HVAC fan at different speeds to confirm normal airflow and no rattles.
- 🔸 If you hear tapping/rubbing behind the glove box, recheck that the filter cover is fully clipped in.
