🔧 Grand Cherokee - Cabin Air Filter Replacement

The cabin air filter on your Grand Cherokee cleans the air that comes through the vents into the interior. You’ll replace the filter behind the glove box so your A/C and heater blow cleaner air and reduce odors.

📋 Before You Begin

• 🔹Empty the glove box so nothing falls out when you move it.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and lower the glove box

• 🔹Open the glove box fully on the passenger side.
• 🔹On the right side of the glove box, locate the small arm or cord (this is the glove box damper that slows its movement).
• 🔹Use your hands to gently unclip or slide the damper arm off its pin on the glove box side.
• 🔹On both sides of the glove box, gently squeeze the sides inward so the side stops clear the dash opening and the glove box can swing down further.
• 🔹Let the glove box hang down carefully; support it with one hand so it doesn’t drop suddenly.
• Torque spec: Not applicable (no bolts yet).

Step 2: Remove the glove box rear panel (if equipped)

• 🔹Behind the lowered glove box, you may see a thin plastic panel or trim piece covering the HVAC area.
• 🔹Use the trim removal tool (plastic) to gently pry the edges of this panel free if present.
• 🔹If there are any small screws holding a trim piece, remove them with the Phillips screwdriver and set them aside in a safe place.
• Take a quick photo before removing parts.
• Torque spec: Not applicable (hand-tight screws only on reassembly).

Step 3: Locate the cabin air filter door

• 🔹Shine the flashlight behind the glove box area.
• 🔹Look for a rectangular black plastic cover running left-to-right; this is the cabin filter access door on the HVAC housing.
• 🔹You’ll see small clips or tabs on the sides or bottom of this cover.
• Move slowly and look carefully; space is tight.
• Torque spec: Not applicable (snap-on cover).

Step 4: Open the cabin filter door

• 🔹Use your hands to press or pull the tabs on the filter door; some doors hinge downward, others slide out.
• 🔹Gently swing or slide the cover off and set it aside.
• 🔹Confirm you can see the edge of the old cabin filter inside the opening.
• Torque spec: Not applicable (no fasteners).

Step 5: Remove the old cabin air filter

• 🔹Put on your mechanic’s gloves and safety glasses in case of dust or debris.
• 🔹Grasp the exposed edge of the old filter with your fingers and slowly slide it straight out towards you.
• 🔹If it catches, wiggle it gently side to side without forcing it; don’t bend it too sharply.
• 🔹Once removed, keep the dirty side facing away from you and place it directly into a trash bag.
• Torque spec: Not applicable.

Step 6: Clean the filter housing area

• 🔹Use the small shop vacuum to carefully vacuum any leaves, dust, or debris at the opening and just inside the housing.
• 🔹Do not stick any hard tools deep into the housing; just clean the visible area.
• 🔹If using HVAC deodorizer spray, lightly mist into the filter opening following the product instructions.
• A small paint brush can loosen stuck dust.
• Torque spec: Not applicable.

Step 7: Install the new cabin air filter (correct direction)

• 🔹Take the new cabin air filter out of its packaging.
• 🔹Look for an arrow on the side of the filter that says "AIRFLOW" or shows a direction.
• 🔹On the Grand Cherokee, air typically flows from top to bottom, so install the filter with the arrow pointing down (match any markings you saw on the old filter).
• 🔹Gently slide the new filter into the housing, keeping it square so it doesn’t bend; it should fit snugly but not require force.
• If it won’t go, flip it 180° and try.
• Torque spec: Not applicable.

Step 8: Reinstall the cabin filter door

• 🔹Align the cabin filter access door with its opening on the housing.
• 🔹Use your hands to snap the tabs or clips back into place; you should feel or hear them click.
• 🔹Double-check that all sides of the cover are fully seated so unfiltered air cannot bypass the filter.
• Torque spec: Not applicable (snap fit).

Step 9: Reinstall the glove box trim and glove box

• 🔹If you removed a plastic panel, align it and press it back into place by hand; if it had screws, reinstall them with the Phillips screwdriver snugly, but do not overtighten.
• 🔹Lift the glove box back up into its normal position.
• 🔹On both sides, gently squeeze the glove box again so the side stops slide back inside the dash opening, then release.
• 🔹Reattach the damper arm on the right side by hand, snapping it back onto its pin.
• 🔹Open and close the glove box a few times to confirm smooth movement.
• Torque spec: Hand-tight only on any screws; do not overtighten.

✅ After Repair

• 🔹Start the engine and turn on the blower fan at low speed first, then higher speeds, and check for normal airflow from the vents.
• 🔹Switch between different vent modes (face, feet, defrost) to confirm air is flowing correctly.
• 🔹Listen for any unusual noises near the glove box area; if you hear rubbing, the filter may not be seated correctly and should be checked.
• 🔹If you used deodorizer spray, run the fan for a few minutes with windows slightly open to vent any strong smell.
• 🔹Refill the glove box and make sure it latches securely.
