đź”§ QX50 - Cabin Air Filter Replacement
Your QX50’s cabin air filter cleans the air coming through the HVAC vents (A/C and heat). Replacing it helps reduce dust, odors, and weak airflow, and can prevent blower motor noise from a clogged filter.

đź“‹ Before You Begin
- Park on level ground and set the parking brake.
- Move the front passenger seat back to give yourself room.
- Assumption: filter access is behind 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.
- Open the glove box fully.
- Use a flashlight to look along the right side of the glove box area.
Step 2: Release the glove box damper strap
- On the right side, find the small damper strap (it’s a little arm that slows the glove box).
- Use a trim removal tool (plastic) to gently pop the strap off its pin.
- Tip: Pry close to the pin, not the strap.
Step 3: Drop the glove box down
- Press in on both glove box side walls to clear the stops (the “stops” are plastic tabs that prevent it from dropping too far).
- Let the glove box swing downward carefully.
- If a small panel/cover is in the way near the filter area, remove it using a Phillips screwdriver #2.
Step 4: Remove the cabin filter access door
- Locate the rectangular cabin filter door behind the glove box area.
- Release the door tabs by hand, or gently with the trim removal tool (plastic), then pull the door off.
Step 5: Pull out the old cabin filter
- Wear nitrile gloves (old filters can be dusty).
- Slide the filter straight out. If it resists, wiggle it gently—don’t yank.
- Note the airflow arrow (or “UP” marking) on the old filter so the new one goes in the same direction.
Step 6: Install the new cabin filter
- Compare the new filter to the old one to confirm the same size.
- Install the new filter with the airflow arrow oriented the same way as the old filter.
- Push it fully in until it sits flat (no bending or bunching).
Step 7: Reinstall the access door and glove box
- Reinstall the cabin filter door by hand until the tabs click in.
- Lift the glove box back up and press the sides in to re-seat the stops.
- Reattach the damper strap to its pin by hand.
- If you removed any screws/panels, reinstall them using the Phillips screwdriver #2.
âś… After Repair
- Start the engine and run the blower on all speeds to confirm good airflow and no rattles.
- Switch between fresh-air and recirculate modes to confirm normal operation.
- If you notice a whistle noise, the filter may not be seated flat—recheck the access door and filter alignment.
