This automotive "how-to" guide was specifically written to assist owners of the sixth generation (2011, 2012 & 2013) Hyundai Sonata in cleaning or replacing the A/C system's cabin air filter element.

Owners of other Hyundai or Kia vehicles such as the Elantra, Accent, Veloster, Tucson, Santa Fe, Veracruz, Genesis, Forte, Optima, Rio, Soul, Sedona, Sorento, Tiburon and Sportage may also find these DIY instructions to be helpful.

A few compatible replacement cabin air filter elements for the Hyundai Sonata include the following with their respective part numbers: ACDelco CF177, Wix 24013, Hyundai / Kia OEM # F784EB9AA, and NPN # W0133-1897600.

No tools are needed to access the HVAC cabin air filter element in a 2011, 2012 or 2013 Hyundai Sonata.

Pull Off Damper Arm
Rubber Stopper
1/4 Turn Counter Clockwise
The first few steps are to get into the front passenger seat of the vehicle, open the glove box, empty out the contents and locate the damper arm mechanism on the outer right side of the box.

Pull the damper arm straight off its mounting peg. If you have trouble removing it, use a small screwdriver to pry it off while pinching the two prongs on the end of the peg together.

Right Side Stopper
1/4 Turn Counter Clockwise
Remove Side Stopper
Then move to the inside of the glove box and locate the two dials for the side stopper pegs. Rotate each dial 1/4 turn counter clockwise (away from you) and pull them straight out of the glove box's side walls.

Gently lower the glove box down to the passenger floor mat.

Cover Retaining Clip
Behind the glove box, you'll be able to see the rectangular black plastic cabin air filter access cover attached to the front of the A/C blower motor housing.


Pinch Pieces Together
Remove Filter Access Cover
Filter Cover Removed
Pinch the two prongs on the right side of the cover together and swing the filter cover away from the right side until the tab on the left side can be pulled out of its slot.
Slide Out Old Air Filter
Filter Part # F784EB9AA
Air Flow Indicator Arrow
Slide the old cabin air filter out of its slot and make a mental note of how the air flow indicator arrow is orientated. In this 2011 Hyundai Sonata and most other vehicles, the air flow indicator should be pointing down towards the floor mat.
Old A/C Filter Removed
Clean With Wet/Dry Vacuum
Blower Motor Housing
If your old cabin air filter doesn't look too dirty like the one pictured above, just tap out any large debris and/or use a wet/dry shop vacuum to clean the element. Then re-insert it back into the blower motor housing.

If your old filter is dark grey or black and clogged with dirt, dust, hair, leaves, insects, twigs, etc, it should be replaced with a new filter element.

Slide In New HVAC Filter
Air Flow Arrow - Down
Replace Left Side Cover
Slide the cleaned or new cabin air filter element back into the slot with the air flow indicator arrow on the side of the filter pointing down towards the floor mat.
Snap Fastener On Right Side
Filter Access Cover Replaced
Raise Glove Box
Replace the cabin air filter access cover by first inserting the tab on the left side into the slot on the left. Then swing the right side of the cover closed and push it in place until the fastener clicks.
Side Rubber Stopper Hole
Insert Side Stopper Peg
1/4 Turn Clockwise To Secure
Raise the glove box up until the holes for the side stopper pegs are clear of the dashboard.

Insert the side stopper pegs into their holes and rotate them 1/4 turn clockwise to lock them into place.

Replace Other Side Stopper
Re-Attach Damper Arm
Close Glove Box
Move to the right side of the glove box and snap the damper arm back into place on its mounting peg.

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