Take charge of a fogged-over back window with the Standard Ignition switch DFG43, a rear window defogger (defroster) switch that lets the driver turn the rear glass defogger on and off. It is a direct-fit OE replacement for many vehicles, among them the 1999-2001 Ford Explorer, 2002 Ford Explorer Sport, and 2001 Ford Explorer Sport Trac.
The switch is the driver's control for the rear defogger circuit, which warms the heating grid in the back glass to help clear fog and frost. If the defogger no longer comes on when the switch is pressed, or works only some of the time, a failed switch may be the cause. A fuse, wiring, or grid fault can cause the same symptoms, so check the circuit before replacing the switch.
