Defogger relay
The rear window defogger relay is a International Standards Organization (ISO)-type relay. The rear window defogger relay is a electromechanical device that switches fused battery current to the rear glass and outside mirror heating grids, and the indicator lamp of the defogger switch, when the instrument cluster rear window defogger timer and logic circuitry grounds the relay coil. See Defogger Relay in the Diagnosis and Testing section of this group for more information.
The rear window defogger relay is located in the junction block, on the right cowl side inner panel below the instrument panel in the passenger compartment.
The rear window defogger relay cannot be repaired and, if faulty or damaged, it must be replaced.
