The 2000 Lincoln Navigator uses an automatic suspension system that adjusts the shocks and suspension components during driving to improve handling. The system works by monitoring front and rear sensors that measure the distance from the surface to the vehicle, usually referred to as ride height. The air suspension switch allows the owner to turn off the automatic system to perform maintenance on the suspension components. The air suspension switch is easy to find and a novice mechanic can easily accomplish the procedure.
Remove the scuff plate that covers the carpet seam from the passenger door frame. Pull the scuff plate straight up to pop it out, or use a screwdriver if necessary.
Remove the right kick panel on the passenger side of the vehicle under the dash with your fingers by pulling it toward the center of the vehicle.
Look for the switch behind the right kick panel, labeled "Air Suspension Switch."
