General Description - Rear Window Defogger & Heated Mirrors

PURPOSE
The rear window and outside mirror defoggers are a standard feature on all vehicles. The system is designed to remove fog and ice from the rear window and outside mirrors, providing the driver with clear rearward vision.

OPERATION
To operate the rear defogger, the engine must be running and the rear defogger button on the Climate Control Panel must be momentarily depressed. System activation is indicated by the illumination of the rear defogger annunciator symbol on the Climate Control Panel display and the LED in the rear defogger button. Momentarily depressing the rear defogger button again after the system has been turned on will turn the defogger off.

When the system is turned on, power is supplied to heating elements which are imbedded in the rear window and outside mirrors glass. The heating elements warm the glass, causing the fog or ice to dissipate. The first time the system is activated during an ignition cycle it will operate for 10 minutes. Subsequent activations of the rear defogger after the initial 10 minute cycle will last approximately 5 minutes.
