Rear Defogger Relay - Description
DESCRIPTION
The rear window defogger (EBL) relay (1) is an International Standards Organization (ISO) relay. Relays conforming to the ISO specifications have
common physical dimensions, current capacities, terminal functions and patterns (2). The EBL relay is a electromechanical device that switches battery
current through a fuse located in the integrated power module (IPM) 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 front control module (FCM).
The EBL relay is located in the IPM in the engine compartment.
