This automotive maintenance tutorial was specifically written to assist owners of the "new" Type 312 (2008, 2009, 2010, 2011, 2012, 2013, 2014 and 2015) Fiat 500 compact car in cleaning or changing the air conditioning system's cabin air filter element located in the HVAC blower motor housing.

Owners of other Fiat, Alfa Romeo, Chrysler, Dodge, Jeep and RAM vehicles such as the 4C, Giulia, 200, 300, Town & Country, Challenger, Charger, Dart, Durango, Journey, Grand Caravan, Compass, Grand Cherokee, Wrangler, Renegade, Cherokee, Patriot, 1500, C/V Tradesman and ProMaster may also find these DIY instructions to be helpful.

A few compatible replacement filters with their part numbers are as follows: Ecogard XC26185, Beck Arnley 042-2186, GKI CF1249, Hastings AFC1580, Wix 24053, Premium Guard PC6185 and Mahle Original LA241/3.

The tools needed to access and replace the cabin air filter include a Torx T25 screwdriver, a flathead screwdriver or pop rivet removal tool, a 5.5mm socket and a ratcheting wrench.

Gently Pull Off Panel
To access the HVAC blower motor housing and the A/C cabin air filter, you'll need to remove the front passenger left side kick panel and the fabric cover under the glove box.

Loosen the single screw near the center of the kick panel by turning it counterclockwise with a Torx T-25 star bit screwdriver.

Set the T25 screw aside in a safe place.

Gently pull out the kick panel to release the metal retaining clips.

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

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

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

I recommend buying the Mahle Original LA241/3 cabin air filter since it has great reviews on Amazon.
