Heated Glass Element Switch: Description and Operation

Rear Window Defogger Switch Location:

The rear window defogger switch is a control switch and timing circuit integrated into a single panel mounted assembly. The switch is located on the instrument panel center, just below the radio. The rear window defogger switch and the rear window defogger switch LED indicator cannot be repaired and, if faulty or damaged, the entire switch assembly must be replaced.

Actuating the switch energizes the circuit which allows current to flow through the grid lines. Upon initial actuation for approximately eight to ten minutes, or until either the switch or ignition is turned OFF. An indicating lamp illuminates a Light Emitting Diode (LED) inlaid in the control switch.
