2006 Chevy HHR
Open Glove Box - Empty
Right Side - Damper Arm
This automotive maintenance tutorial was specifically written to assist owners of the 2006, 2007, 2008, 2009, 2010 and 2011 GM Chevrolet HHR in cleaning or changing the A/C system's cabin air filter element located in the HVAC blower motor housing.

Owners of other General Motors vehicles from Chevrolet, Buick, GMC and Cadillac such as the Spark, Sonic, Malibu, Trax, Cavalier, S-10, SSR, Cobalt, Cruze, Captiva, LeSabre, Regal, Verano, Lucerne, LeSabre, DeVille, CTS, STS and Canyon may also find these DIY instructions to be helpful.

A few compatible replacement cabin air filters with their part numbers are as follows: Bosch 6060C, Fram CF10361, EcoGard XC35676, Premium Guard PC5676, ACDelco CF125 and Wix 24882.

The tools needed to access and replace the filter include a 7mm socket and a 1/4" drive ratchet.

The first few steps are to sit in the front passenger seat, open the glove box and empty out the contents.

Move to the right outer side wall and locate the glove box damper arm.

The damper arm is secured in place by a single 7mm screw.

If you have a 7mm wrench, you can remove the screw at this time.

I had trouble getting my 7mm socket and 1/4" drive ratchet into the small space, so I instead went with releasing the two side stops first.


Tight Fit - Can't Loosen
Push In Two Side Walls
Lower Glove Box
Firmly push in the two side walls of the glove box until the plastic side stops can be released from behind the dashboard.

Gently lower the glove box down towards the floor mat.

Don't worry if the plastic hinges on the bottom of the glove box come apart.

They can be re-attached later on.

Loosen Counterclockwise
Detach Damper Arm
HVAC Blower Motor
If you haven't already detached the damper arm, use the 7mm socket and a 1/4" drive ratchet to loosen the screw in the counterclockwise direction.

Set the screw aside in a safe place.

Pull the damper arm off the mounting peg on the right outer side wall of the glove box.

Allow the glove box to lower down to the floor mat.

3 Tabs - Retaining Clips
Pull Out To Release
Release Third Clip
Once the glove box is out of the way, you'll be able to see the rectangular shaped black plastic filter access cover.

There are three tabs on the top edge of the filter access cover.

Gently pull the tabs out towards yourself to release the three retaining clips.

Swing Down, Open Cover
Slide Out Old Filter
Clean Filter Slot
Swing open the filter cover.

Slide the old filter straight out of the slot.

Check both sides of the old filter.

If the old cabin filter is dark gray or black and clogged with dirt, dust, pollen, soot, leaves, insects, hair, sand and other debris, it should be replaced with a new element.

I recommend purchasing the Bosch P3808WS cabin air filter since it has excellent reviews from other Chevy owners.

If the old filter is relatively clean, just tap out the large debris and remove any fine dust with a wet/dry shop vacuum.

Check the filter slot for any debris.

If necessary, clean out the slot with the crevice attachment of your wet/dry shop vacuum.

The OEM (original equipment manufacturer) part number is GM 52493319.

Install New Filter
Replace Glove Box
Filter Change Done!
Orientate the new filter with the "Air Flow" arrow pointing down.

If the new filter has an "UP" arrow, make sure it is pointing in the up direction.

Slide the new filter straight into the slot.

Make sure it is fully seated in the housing.

Swing up the filter cover and push on it to secure the three retaining clips.

You should feel or hear the three retaining clips "click" securely into place.

Raise the glove box towards the dashboard.

Line up the screw hole on the damper arm with the mounting peg.

Replace the screw by turning it in the clockwise direction with the 7mm socket and a 1/4" drive ratchet until it is snug.

Firmly push in the two side walls of the glove box until the plastic side stops can be re-inserted behind the dashboard.

Replace the contents of the glove box and close it to complete the job.

The service interval specification in the owner's manual for changing the passenger compartment air filter is every 15,000 miles.

If you often drive off-road or on dusty or sandy roads, check, clean and replace the filter more often.

Be sure to record the filter change in your vehicle's service records.

Enjoy the fresh clean air from your A/C system!
