2014 Impala Glove Box
Open - Empty Out
Glove Box Damper Arm
This automotive maintenance tutorial was specifically written to assist owners of the tenth generation (2014, 2015, 2016, 2017 and 2018) GM Chevy Impala 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 Malibu, Cruze, Camaro, Sonic, Spark, Volt, Corvette, Trax, Equinox, Traverse, Tahoe, Suburban, SS Sedan, Bolt, Colorado, Silverado, Buick Verano, Regal, LaCrosse, Cascada, Encore, Envision, Enclave, Canyon, Sierra 1500, Terrain, Acadia, Yukon, Savana, ATS, CTS, XTS, CT6, XT5, SRX and Escalade may also find these DIY instructions to be helpful.

A few compatible replacement filters with their part numbers are as follows: ACDelco CF184, Cleenaire CAF184, Wix 24211, Original Engine Management CAF297C, UAC FI 1232C, Bosch P3720WS, MAHLE LAK 758, ATP CF-247, and Hastings AFC1624.

The only tool needed to complete this procedure is a standard Phillips head screwdriver.

Pull Damper Arm Off Peg
Firmly Push In Side Walls
Release Side Stops
The first few steps are to sit in the front passenger seat, open the glove box and empty out the contents.

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

Gently pop the glove box damper arm off its two pronged mounting peg.

Firmly push in the two side walls of the glove box until the plastic side stops can be removed from behind the dashboard.

Lower the glove box down to the floor mat.

Three Bottom Screws
Loosen Counterclockwise
3 Lower Screws Removed
To access the HVAC blower motor housing and the cabin air filter, you'll need to remove the plastic panel located behind the glove box.

There are seven screws holding the panel in place.

Remove the 3 screws near the bottom edge of the panel by turning them counterclockwise with the Phillips head screwdriver.

Remove the four upper Phillips head screws by turning them counterclockwise.
7 Screws Removed
Gently Pull Out Panel
Plastic Access Panel
Set the top screws aside with the other screws.

At this point, you should have removed a total of seven Phillips head screws.

Gently pull out the plastic access panel to reveal the HVAC blower motor housing.

Set the plastic panel aside in a safe place.

Slide Out Old Filter
Old Filter Removed
Empty Filter Slot
Slide the old cabin air filter straight out of the slot in the HVAC blower motor housing.

If your vacuum cleaner has a crevice attachment, clean out any debris that might be stuck inside the filter slot.

Inspect Both Sides

Clean With Vacuum
Inspect both sides of the old air filter.

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

I recommend buying the ACDelco CF184 cabin air filter since it has excellent reviews on Amazon.

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

GM Part # 13356914
"Down" Air Flow Arrow
Slide In New Air Filter
If the new filter has an "Air Flow" or "Down" arrow on it, make sure it is pointed down towards the floor mat.

Slide the new air filter straight in to the slot.

Cover Under Wire Loom
Close Filter Cover
Push To Secure Clips
Line up the filter access cover with the slot.

Slide the right side of the filter cover under the black wire loom.

Firmly push on both sides of the filter access cover to secure the two retaining clips.

Double check that the filter cover is securely in place before moving on to the next steps.

(If you need to change a burnt out glove box light bulb or upgrade it to a brighter LED, now is the easiest time to do it.)

Re-Insert Plastic Panel
Snap Panel In Place
Tighten Clockwise
Re-insert the plastic panel in front of the HVAC blower motor housing.

Replace the top four screws and tighten them in the clockwise direction with the Phillips head screwdriver.
