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.
