Removal Procedure

The door jamb switch assemblies consist of the following components:

    • Plunger
    • Collar
    • Threaded retainer
    • Terminals

The components are installed in the rear door hinge pillars. The plunger is depressed which creates an open in the ground circuit when the door is closed. The plunger is released and completes the circuit to the ground when the door is opened. When a new jamb switch is installed and the door is closed the first time, the plunger is forced into the sleeve and automatically adjust the jamb switch for that particular door. If a jamb switch fails, do not readjust the switch. Install a new jamb switch.
