2022 GMC Sierra 1500 Cabin Air Filter Replacement — 10-Minute DIY Guide
2022 GMC Sierra 1500 Cabin Air Filter Replacement — 10-Minute DIY Guide
I skipped replacing the cabin air filter on my last truck for too long because I assumed it would be a hassle. Then I popped the glove box out of my 2022 Sierra and replaced the filter in under 10 minutes with zero tools. I'd been breathing through a clogged filter for two years and paying the dealer $40 to do it.
Here's how to replace the cabin air filter on the 2022 GMC Sierra 1500.

Which Filter Fits?
The 2022 Sierra 1500 uses the same filter as the 2022 Silverado 1500 — ACDelco CF188. This applies to all cab configurations (Regular, Double, Crew) and all trims (Pro, SLE, SLT, AT4, Denali).
If you have a 2022 Sierra 1500 with the Premium HVAC system (available on AT4 and Denali), the filter is the same part. If you're buying aftermarket, cross-reference your VIN to confirm — some aftermarket fitment guides get the 2022 wrong.
Step-by-Step
1. Open the Glove Box
Open the glove box fully. On the 2022 Sierra, you'll see the glove box held by a damper strap on the right side and the box itself sitting on its hinges.
2. Release the Glove Box Stops
On both sides of the glove box opening, there are small plastic bumpers or tabs. Squeeze the sides of the glove box gently and push them inward past the stops. The glove box will swing down past its normal stop position.
No tools needed. This is a squeeze-and-lower operation. Don't force it — if it's not moving, you haven't squeezed enough.
3. Locate the Filter Housing
With the glove box lowered, you'll see the rectangular filter housing on the back wall of the HVAC box. It has a tabbed access door secured by one or two clips.
4. Open the Filter Door
Unclip the door tab(s) and swing the door open. Pull the old filter straight out toward you.
5. Note the Airflow Direction
Before installing the new filter, look at the arrows on the filter frame and on the housing. The airflow direction matters — install the filter with the arrow pointing toward the blower (generally upward or rearward, depending on orientation). Installing it backward reduces filtration efficiency and can cause the filter to flex and bypass air around the edges.
6. Install the New Filter
Slide in the new ACDelco CF188 (or equivalent) in the correct orientation. The filter should slide smoothly — don't force it. If it catches, check that you have the right part number.
7. Close the Door and Restore the Glove Box
Snap the filter door closed. Then lift the glove box back into position, squeeze the sides, and let it click back past the stops. The box should sit normally.
8. Test the HVAC
Turn on the AC or heat. You should notice improved airflow immediately if the old filter was clogged. If you hear any new rattling from the HVAC box, the filter may be seated off-center — recheck.
How to Tell If Your Filter Needs Replacing
Pull the old filter out and hold it up to a light. A new filter is nearly white and light passes through easily. A filter due for replacement looks gray or brown, and light may not pass through well at all. If you see visible debris — leaves, insects, dirt — it's overdue.
On high-mileage trucks or trucks kept in dusty or rural environments, check the filter annually regardless of mileage.
Cost Comparison
| DIY | GM Dealer | |
|---|---|---|
| ACDelco CF188 filter | ~$15–$22 | — |
| Labor | $0 | $25–$45 |
| Total | ~$15–$22 | $55–$80 |
This is one of the highest-ROI jobs in all of car maintenance. You're paying $40–$60 in labor for a job that takes 10 minutes and zero tools.
Does It Affect Performance?
Yes, but not the engine. The cabin air filter affects:
- HVAC airflow volume — a clogged filter reduces air output from your vents
- AC efficiency — restricted airflow makes the AC work harder to cool or heat the cabin
- Odors — a charcoal-lined filter (like the K&N VF2052) helps with road and exhaust smells
Replacing a clogged cabin filter often fixes a complaint of "weak AC" that has nothing to do with refrigerant levels.
Common Mistakes
1. Installing the filter backward. The airflow direction arrow must point the correct way. Check the housing markings.
2. Buying the wrong size. The 2022 Sierra uses a different filter than the 2021 (different HVAC box). Confirm fitment by VIN, not just year/model.
3. Skipping this job because the car "seems fine." A severely restricted cabin filter reduces airflow gradually — you adapt to weaker AC output without realizing the filter is the cause.
