🔧 Elantra - Cabin Air Filter Replacement

Your Elantra’s cabin air filter cleans the air coming through the HVAC vents (heat/AC). Replacing it restores airflow, reduces odors, and helps the blower motor work less.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the glove box

• Open the glove box fully and remove any items inside.
• Use a flashlight to look along the right side of the glove box for a small “damper” arm (a little strap that slows the glove box). Damper = slow-drop strap.

Step 2: Disconnect the glove box damper

• Use your hands (wear clean nitrile gloves) to gently pop the damper arm off its pin on the glove box.
• If it feels stuck, wiggle it gently—do not pry hard.

Step 3: Drop the glove box down

• Press inward on both sides of the glove box to clear the side “stops” (the bumps that keep it from falling).
• Lower the glove box down slowly until it hangs open, giving access behind it.

Step 4: Remove the cabin filter cover

• Behind the glove box, find the rectangular cabin filter housing cover.
• Use your hands to press the locking tabs and pull the cover straight off.

Step 5: Remove the old cabin air filter

• Slide the old filter straight out.
• Use the flashlight to note the airflow direction arrow on the filter (or on the housing).
• Tip: Keep it level to avoid spilling debris.

Step 6: Install the new cabin air filter

• Slide the new filter into the slot in the same orientation as the old one.
• Make sure the airflow arrow matches the housing direction (typically “DOWN” in the Elantra).
• Do not crush or fold the filter—push it in evenly.

Step 7: Reinstall the housing cover and glove box

• Reinstall the filter cover by pushing it on until the tabs click.
• Lift the glove box back up, press the sides inward again, and guide the stops back past the opening.
• Reconnect the glove box damper arm onto its pin by pushing it on until it snaps in place.
• Torque to N/A (hand-secure plastic clips; no torque spec)

✅ After Repair

• Start your Elantra and run the fan at speeds 1–4 to confirm strong airflow.
• Switch between fresh air and recirculation to ensure the glove box area has no rattles.
• If there’s a new noise, recheck that the filter cover is fully clipped in.
