DESCRIPTION





The rear window defogger switch (1) is integrated into the A/C-heater control (2) located in the instrument panel. When the rear window defogger switch is activated, the A/C-heater control requests the body control module (BCM) to operate the rear window defogger (EBL) relay.

When the EBL relay is activated, current is directed to the rear defogger grid lines and the heated side view mirrors (if equipped). The grid lines heat the glass to help clear the surface of fog or frost.
