🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and empty the glove box

• Open the glove box fully.
• Remove anything inside (manuals, papers, etc.).
• Use a flashlight so you can see the right-side damper.

Step 2: Disconnect the glove box damper

• On the right side of the glove box, find the small “damper” arm (a little plastic strut that slows the glove box). A damper is a small limiter that prevents the glove box from dropping fast.
• Use your hand (gloves help grip) to pop the damper arm off its pin or unhook it from the glove box.

Step 3: Drop the glove box down

• Gently push in on both sides of the glove box to clear the side stops.
• Let the glove box swing downward to expose the cabin filter housing behind it.
• Go slow—don’t bend the sides too far.

Step 4: Remove the cabin filter cover

• Locate the rectangular filter access door (usually near the center behind the glove box).
• Press the locking tabs and pull the cover straight off by hand.
• Use a flashlight to confirm the tab locations before pulling.

Step 5: Remove the old cabin air filter

• Slide the old filter straight out.
• Keep it level to avoid dumping leaves/debris into the blower housing.
• Check the filter for an airflow arrow printed on the side.

Step 6: Install the new cabin air filter

• Insert the new filter in the same orientation as the old one.
• Match the printed arrow on the filter to the housing marking:
  • If it says AIR FLOW, the arrow typically points down toward the floor in your C-HR.
  • If the housing has an UP marking, align the filter’s UP arrow accordingly.
• Make sure the filter seats fully and doesn’t buckle.

Step 7: Reinstall the cover and glove box

• Snap the filter cover back on until the tabs click.
• Lift the glove box back up and push in the sides to get past the stops again.
• Reattach the right-side damper arm to its pin/hook.
• Close the glove box and verify it opens/closes smoothly.

✅ After Repair
