🔧 Wrangler - Cabin Air Filter Replacement

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Empty and Open the Glove Box

• Use your hands to open the glove box fully.
• Remove all contents from the glove box.
• Use a flashlight to look at both sides of the glove box opening.
• Keep screws and small items in a cup.

Step 2: Release the Glove Box Stops

• Use your hands to gently squeeze both sides of the glove box inward.
• The glove box stops are small molded tabs that prevent the glove box from dropping too far.
• While squeezing the sides inward, lower the glove box down toward the floor.
• If the plastic feels stiff, use a small flat-blade screwdriver gently at the stop area, but do not pry hard.

Step 3: Locate the Cabin Filter Door

• Use a flashlight to look behind the lowered glove box.
• Find the rectangular cabin filter access door on the HVAC housing.
• The HVAC housing is the black plastic box that holds the heater and A/C air passages.

Step 4: Remove the Cabin Filter Access Door

• Use your fingers to press the release tab on the cabin filter door.
• If the tab is tight, use a small flat-blade screwdriver to gently depress the tab.
• Pull the access door straight off and set it aside.
• There is no torque spec for this cover because it clips on by hand.

Step 5: Remove the Old Cabin Air Filter

• Use your fingers to slide the old cabin air filter straight out of the housing.
• Watch the airflow arrow on the old filter before removal.
• The airflow arrow shows which direction air moves through the filter.
• Keep the old filter level as you remove it so debris does not spill inside the dash.

Step 6: Clean the Filter Area

• Use a shop vacuum to remove leaves, dust, and loose debris from the filter opening.
• Use a flashlight to check that nothing is blocking the slot.
• Do not push the vacuum nozzle deep into the HVAC housing.
• Gentle cleaning prevents rattles later.

Step 7: Install the New Cabin Air Filter

• Use your hands to slide the new cabin air filter into the housing.
• Match the airflow arrow direction to the marking on the housing or to the direction of the old filter.
• Slide the filter in slowly so it does not fold or crush.
• The filter should sit flat and fully inside the slot.

Step 8: Reinstall the Filter Door

• Use your hands to place the cabin filter access door back onto the HVAC housing.
• Press until the tab clicks into place.
• Gently tug the door by hand to confirm it is secure.
• No torque spec applies because this is a plastic snap-fit cover.

Step 9: Reinstall the Glove Box

• Use your hands to raise the glove box back into position.
• Squeeze both sides inward slightly so the stops pass back through the dash opening.
• Release the sides once the glove box is back in place.
• Open and close the glove box by hand to confirm smooth movement.
