Heated Glass Element Relay: Description and Operation
Description
DESCRIPTION
The rear window defogger (EBL) relay (Figure 1) is an International Standards Organization (ISO)-type relay. Relays conforming to the 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 integrated power module (IPM) to the rear window defogger grid and switches battery current through a
positive thermal coefficient (PTC) in the IPM to the outside mirror heating grids. 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.
