This automotive maintenance tutorial was specifically written to assist owners of the first generation (2010, 2011, 2012, 2013, 2014, 2015 & 2016) GMC Terrain in cleaning or changing the A/C system's cabin air filter element in the HVAC blower motor housing.

Owners of other General Motors vehicles such as the Buick Verano, Regal, LaCrosse, Cascada, Encore, Enclave, Envision, GMC Canyon, Sierra 1500, Acadia, Yukon, Denali, Savana, Spark, Sonic, Cruze, Malibu, Impala, Volt, Camaro, Corvette, SS, Trax, Equinox, Traverse, Tahoe, Suburban, Colorado, Silverado and Express may also find these DIY instructions to be helpful.

No tools are needed to access and replace the filter.

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

Locate the large black plastic tab at the top of the opening in the dashboard for the glove box.

Gently push back the plastic tab and pull down the top edge of the glove box until it can be lowered past the tab.

Lower the glove box and disengage the plastic "C" shaped sockets from the plastic mounting bars on the bottom of the opening in the dashboard.

Inspect Both Sides

Clean With Vacuum
Inspect both sides of the old filter.

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

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

I recommend buying the FRAM CF11819 "Fresh Breeze" cabin air filter since it has excellent reviews on Amazon.

I also like how it has Arm & Hammer baking soda and carbon in the filter to help stop the A/C system from smelling musty or moldy.

New Cabin Filter Installed
If your vacuum has a crevice attachment, clean out any debris that might be stuck in the filter slot within the HVAC blower motor housing.

If the new filter has an "Air Flow", "Up" or "Down" arrow, orientate it in the correct direction.

An "Air Flow" arrow should be pointing down towards the floor mat.

Slide the new filter straight in to the slot.
