Heated Glass Element Relay: Description and Operation






DESCRIPTION





The relay (1) for the rear window defogger system, also known as the Electric Back Light (EBL), is an International Standards Organization (ISO) type relay. Relays conforming to ISO specifications have common physical dimensions, current capacities, terminal functions and patterns. The EBL relay is a electromechanical device that switches battery current through a fuse in the Power Distribution Center (PDC) to the rear window defogger grid. The EBL relay is energized when the relay coil is provided a ground path by the control circuitry within the Body Control Module (BCM).

The EBL relay is located in the PDC, in the engine compartment.
