🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and empty the glove box

• Remove items so nothing falls out while the glove box is lowered.
• Use a small flashlight to locate the glove box sides and damper area.

Step 2: Lower the glove box to access the filter door

• Gently press in on both sides of the glove box to release the stops so the glove box can swing down farther.
• If your Armada has a small “damper” arm on the right side (a little slow-down strap), carefully unhook it by hand or with a trim clip removal tool.
• Tip: Press one side at a time if tight.

Step 3: Remove the cabin filter access cover

• Behind the glove box, find the rectangular cabin filter cover.
• Release the cover tabs by hand; if a screw is present on your cover, remove it using a Phillips #2 screwdriver.
• Set the cover aside where it won’t get stepped on.

Step 4: Pull out the old cabin air filter

• Wear nitrile gloves and safety glasses.
• Slide the old filter straight out. Keep it level to avoid dumping debris.
• Check the filter slot for leaves/dirt; wipe out gently by hand (no tools needed).

Step 5: Install the new cabin air filter (correct direction)

• Look for the airflow arrow on the new filter’s frame.
• Install it so the arrow matches airflow direction (typically pointing down toward the blower on this style housing).
• Slide the filter in fully—do not crush or fold it.
• Tip: If it won’t slide, re-check orientation.

Step 6: Reinstall the cover and raise the glove box

• Reinstall the filter access cover until the tabs click in place.
• If removed, reinstall the screw using a Phillips #2 screwdriver (snug only—do not over-tighten).
• Reattach the glove box damper arm (if equipped) by hand.
• Lift the glove box and press the sides in again to pass the stops back into place.

✅ After Repair

• Turn on A/C and heat briefly to ensure no unusual noise from the blower.
