🔧 1500 - Cabin Air Filter Replacement

Your 1500’s cabin air filter (if equipped) cleans the air going through the heater/AC before it reaches the vents. Replacing it helps airflow, reduces odors, and keeps dust/pollen down inside the cab.

Assumption: Your 1500 may or may not have the factory cabin filter door; steps below cover both.

Difficulty Level: Beginner | Estimated Time: 0.25-1.0 hours

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Empty and lower the glove box

• Open the glove box and remove anything inside.
• On each side of the glove box, gently push the sides inward with your hands to clear the stops, then let the glove box swing downward.
• Go slow to avoid cracking the glove box.

Step 2: Locate the cabin filter area on the HVAC housing

• Use a flashlight to look behind the glove box at the black HVAC (heater/AC) housing.
• Look for a rectangular filter door/cover (usually with small tabs/latches).

Step 3A: If equipped—remove the filter door

• Press the door tabs by hand, or gently help them with a small flathead screwdriver, then pull the door off.
• If any screws are present on your door, remove them using a 7mm socket with a 1/4" drive ratchet and 6" socket extension.

Step 4A: If equipped—remove and replace the cabin air filter

• Slide the old filter straight out by hand.
• Use a shop vacuum to clean any loose debris around the opening.
• Install the new filter in the same direction as the old one (match the airflow arrow on the filter frame).
• Reinstall the door by snapping it back in place (and reinstall screws with a 7mm socket if your door uses them). Tighten snug by hand (do not over-tighten).

Step 3B: If NOT equipped—confirm the molded cutout area for the retrofit

• If there is no door, look for a rectangular “outline” or flat panel area on the HVAC housing where a filter door would go.
• This is the common retrofit location on the 1500.

Step 4B: If NOT equipped—cut the opening (retrofit)

• Put on safety glasses and nitrile gloves.
• Use a utility knife to carefully cut along the molded outline to create the opening.
• Cut shallow passes and work your way through the plastic. Multiple light cuts are safer.

Step 5B: If NOT equipped—install the new filter and retrofit door

• Use a shop vacuum to remove any plastic shavings and dust.
• Slide the cabin air filter into the opening, following the airflow arrow.
• Install the retrofit door from the kit (it typically clips/screws into place).
• If the kit uses screws, install them with a Phillips screwdriver #2 or 7mm socket (varies by kit) and tighten snug by hand.

Step 6: Reinstall the glove box

• Lift the glove box back up and push the sides inward again so the stops pass, then let it settle into its normal position.
• Open/close it a few times to confirm it moves smoothly.

✅ After Repair

• 🌬️ Start the engine and run the fan on medium-high for 30 seconds to confirm strong airflow and no rubbing noises.
• 👃 If you had musty odors, run A/C for a few minutes and re-check over the next drive.
• 🧾 Write the date/mileage on the filter edge with a marker (easy future reminder).
