Door Switch: Description and Operation
DOOR AJAR SWITCHDESCRIPTION
There are three door ajar switches, one at each door and one in the liftgate latch. The door switches are located in the B-pillar directly below the latch striker plate, and the liftgate switch is integral to the liftgate latch assembly. A door or body harness connector with a service loop connects each switch to the vehicle electrical system. The door ajar switches cannot be adjusted or repaired, and if faulty or damaged, the switch itself or the liftgate latch must be replaced as an assembly. For complete door ajar switch removal procedures, see the appropriate removal procedure.
OPERATION
The door ajar switches are actuated by either door, or the liftgate being opened. When either door or the liftgate is closed and properly latched, its ajar switch is open. When either door or the liftgate is partially latched, its ajar switch is closed. The ajar switches are connected via a harness connector to a body ground and the Central Locking Pump/Security System Module.
