Step-by-Step Instructions

Follow these steps carefully

Know which G80 generation you have

This guide covers 2017–2024 G80s — both the 2017–2020 DH and the 2021-and-up RG3 generations. Both put the cabin filter behind the glove box, so the procedure below is the same either way. Your generation only matters when ordering the filter, not during the job.

Empty the glove box and open it wide

Clear out the glove box — it drops past its normal stops, and anything left inside will tumble out or jam the hinge. Shine a flashlight on its side walls to spot the stop pins and damper. Move the passenger seat back for kneeling room.

Release the stop pins and unhook the damper

Release the stop pins on the glove box's inside — press or slide them inward. Unhook the damper arm from its side pin, or the box can't drop far enough. Rest the box against the dash — never let it hang by the unhooked damper.

🔧 Mechanic's note — Ray Delgado

I've seen the damper arm snap from the box hanging by it one too many times. Always rest the glove box against the dash the second you unhook that arm — never let it dangle.

Unclip the filter door

Unclip the filter door from the HVAC case behind the lowered glove box — small tabs hold it, so release each in its designed direction. Note how the door seated; it must go back exactly the same way to seal.

Pull the old filter and note the arrow

Slide the old filter out and note its airflow arrow — the new filter goes in pointing the same way. Check the housing for debris and wipe it out; grit left behind can cause a faint rattle at high fan speeds.

🔧 Mechanic's note — Ray Delgado

I do this every single time: The airflow arrow trips up more DIYers than anything else on this job. The new filter goes in with the arrow pointing exactly the way the old one came out — snap a phone photo before you pull it.

Install the new filter and re-clip the door

Slide the new filter in with its airflow arrow matching the old one, pressing it home until the frame sits square in the rails. Press the filter door back on until every tab clicks, then run a fingertip around its edge to confirm it's flush.

Lift the glove box home and test the HVAC

Lift the glove box past the stop pins until it seats, then rehook the damper arm — if the box slams down, the damper isn't engaged. Run the fan through all speeds and listen for whistling behind the dash.

All Done!

Test your repair before closing everything up. If something doesn't work right, double-check your steps.

⚠️ Common Mistakes to Avoid

• Forcing the glove box down without releasing the stop pins — the pins crack.
• Forgetting to rehook the damper arm — the glove box then slams open every time.
• Installing the filter with the airflow arrow reversed.
• Ordering without confirming the generation — DH and RG3 take different filter shapes.
