This automotive maintenance tutorial was specifically written to assist owners of the "JL" fourth generation (2017, 2018, 2019, 2020, 2021, 2022 & 2023) Jeep Wrangler SUV in cleaning or changing the A/C system's cabin air filter element located in the HVAC blower motor housing.

Owners of other Jeep, Dodge and RAM vehicles such as the Grand Cherokee, Compass, Renegade, Gladiator, Cherokee, Grand Wagoneer, Wagoneer, Charger, Challenger, Durango, RAM 1500, Promaster, 2500 and 3500 may also find these DIY instructions to be helpful.

The OEM (original equipment manufacturer) cabin air filter part number in this 2020 Wrangler was a Mopar 68301863 (also known as 68301863AA or Mann-Filter CU 24 019).

A few compatible replacement aftermarket filters with their part numbers are as follows: Fram CF12450, Omix-Ada 17719.27, Hastings PA10396, Fun-Driving FD450, TYC 800231P, Champion Labs / Luber Finer CAF10022P.

No tools are required to access and replace the cabin air filter.

The first two steps are to open the glove box and empty out the contents.

Slide the old filter straight out of its slot in the HVAC blower motor housing.

Keep the old filter level to avoid dropping large debris on to the interior of your vehicle.

Inspect Both Sides
OEM Part Number
Check Slot For Debris
Inspect both sides of the old filter.

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

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

Check the filter slot for any large debris such as leaves or dragonflies.

Use the crevice attachment of your shop vacuum to clean out any large debris in the slot.

Then push on the left side of the filter cover to secure the two retaining clips.

You should feel or hear the retaining clips "click" securely into place.

Raise Glove Box
Line Up Damper Arm
Insert Button Into Hole
Raise the glove box towards the dashboard.

You may need to use a bit more force to pop the black plastic tab past the retaining piece at the top of the glove box.

Move the damper arm into place on the left side of the glove box.

Insert the mounting button into the larger hole.

Snap Into Smaller Hole
