2016 Mazda6 Glove Box

This automotive maintenance tutorial was specifically written to assist owners of the third generation (2014, 2015, 2016, 2017 and 2018) Mazda Mazda6 sedan in cleaning or changing the A/C system's cabin air filter element in the HVAC blower motor housing.

Owners of other Mazda vehicles such as the Mazda2, Mazda3, Mazda5, CX-3, CX-5, CX-7, CX-9, and the MX-5 Miata may also find these DIY instructions to be helpful.

A few compatible replacement A/C cabin air filters with their part numbers include the following: Mazda KD45-61-J6X, EcoGard XC10189, Cleenaire CAF4561, Wix 24103, Hastings AFC1588, TYC 800185P, ATP RA-151, Beck Arnley 042-2217, Denso 453-6044 and Universal Air FI 1262C.

No tools are needed to access and replace the filter.

Push Forward To Release
Push In Side Walls
Release Side Stops
The first few steps are to sit in the front passenger seat of the car, open the glove box and empty out the contents.

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

Gently pull the glove box damper arm towards you until it pops off its mounting bar.

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

Lower Glove Box
HVAC Blower Motor Housing
Grab Small Plastic Tab
Gently lower the glove box down to the floor mat.

Once the glove box is out of the way, you'll see the white plastic HVAC blower motor housing.

Grab the small plastic tab at the middle of the old filter and slide it straight out of the slot.

(Most cars have a plastic access panel that covers the front of the blower motor housing and needs to be removed in order to remove the old cabin air filter. There is not a cabin air filter access cover in the Mazda 6.)

Slide Out Old Filter
Inspect Both Sides
Clean With Vacuum
Inspect both sides of the old filter.

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

I recommend buying the OEM Mazda KD45-61-J6X 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.


Empty Filter Slot
"Air Flow" Arrow - Down
Slide In New Air Filter
If the new cabin filter has an "Air Flow", "Up", or "Down" arrow, make sure it is pointing in the correct direction.

The OEM filter has an "Air Flow" arrow that should be pointing down to the floor mat.

Slide the new filter straight in to the slot until it is fully seated.

New Cabin Filter Installed
Raise Glove Box To Dash
Push In Side Walls
Raise the glove box towards the dashboard.

Firmly push in the two side walls until the plastic side stoppers can be re-inserted behind the dashboard.

Re-Insert Plastic Side Stops
Snap On Damper Arm
Close Glove Box
Move to the right outer side wall of the glove box.

Push the damper arm forward to pop the "C" shaped socket on to its mounting bar.

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

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