This automotive maintenance tutorial was specifically written to assist owners of the third generation (2018, 2019 and perhaps also the updated 2020, 2021 and 2022 model years) GM Chevrolet Equinox SUV 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 Chevy, Buick, GMC, Cadillac and Holden such as the Trax, Blazer, Traverse, Tahoe, Suburban, Cruze, Malibu, Impala, Camaro, Cascada, LaCrosse, Encore, Envision, Enclave, Regal, Canyon, Sierra, Terrain, Acadia, Yukon, Savana, XT4, XT5, XT6, Escalade, CTS, XTS, CT6, Astra, Commodore and Trailblazer may also find these DIY instructions to be helpful.

A few compatible replacement cabin air filters with their part numbers include the following: Spearhead BE-966, Fram CF11966, EcoGard XC10022C, ACDelco CF185, Premium Guard PC4211C, TYC 800181P and Wix 24211.

The tools needed to access and replace the filter include a 5.5mm socket, a short extension bar and a 1/4" drive ratchet.

A wet/dry shop vacuum may also be useful if you plan on cleaning and re-using the old filter.

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

Then locate the damper arm on the outer right side wall of the glove box.

Push In Side Walls
Gently pop the damper arm off the two prongs on the end of the plastic mounting peg.

Next, firmly push in the two side walls of the glove box towards the middle until the two plastic side stops can be released from behind the dashboard.

Blower Motor Housing
Once the two side stops have been released, gently lower the glove box down towards the floor mat.

The plastic hinges may separate when you swing the glove box down.

They can easily be re-attached later on.

After the glove box is out of the way, you'll be able to see the rectangular filter access cover on the HVAC blower motor housing.

Left Screw Removed
There are two screws and two retaining clips holding the filter service cover in place.

Loosen the screws by turning them in the counterclockwise direction with a 5.5mm socket and a 1/4" drive ratchet.

I found it easiest to also use a short extension bar on the ratchet to keep my knuckles from scraping on the filter cover.

Old Air Filter Removed

Inspect Both Sides
Slide the old filter straight out of the slot.

Inspect both sides of the old filter.

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

I recommend buying the Spearhead BE-966 cabin air filter since it has excellent reviews on Amazon from other Equinox owners.

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

(The OEM [original equipment manufacturer] filter part number was marked as GM 13508023 or MicronAir GS600001.)

Check the filter slot in the HVAC blower motor housing for any large debris such as leaves, twigs or bugs.

If you have a crevice attachment for your vacuum, clean out the slot.

Orientate the new filter with the "Air Flow" arrow pointing down towards the floor mat.

Slide the new filter straight into the slot.

Tighten Clockwise
Spin in the two screws a turn or two by hand to prevent them from falling down into the dashboard and becoming lost.

Tighten the two screws by turning them in the clockwise direction with the 5.5mm socket and a 1/4" drive ratchet until they are snug.
