### Power Mirrors

Each outside rearview mirror has two reversible motors. One motor adjusts the mirror up and down. The other motor adjusts the mirror left and right. The motors are controlled by the outside rearview mirror remote control switch. The outside rearview mirror remote control switch consists of two different switches. The mirror select switch is used to select the left or right mirror. The mirror position switch controls the movement of the selected mirror.

When the left mirror is selected with the select switch, the mirror position switch controls the left mirror. When the position switch is pressed to the up position, the mirror moves up. When the position switch is pressed to the down position, the voltage polarity to the left mirror is reversed and the mirror moves down.

The left/right motor of the left mirror operates similar to the up/down motor. When the position switch is pressed to the left position, the left mirror moves to the left. When the position switch is pressed to the right position, the voltage polarity to the left mirror is reversed and the mirror moves to the right.

The right mirror operates the same way when the mirror select switch is moved to the right position.

Each mirror motor contains an internal electronic circuit breaker. If a mirror position switch is held in the up/down position or the left/right position after the mirror movement stops, the circuit breaker opens to protect the motor. The circuit breaker also opens to stop the motor if the mirror becomes obstructed during operation. The circuit breaker resets when the voltage to the motor is interrupted.

### Heated Mirrors

When the rear defogger switch is pressed, voltage is momentarily applied to the solid state timer, sending a ground signal to the rear window defogger relay. This energizes the rear window defogger relay closing the switch in the relay. When the rear window defogger relay is energized, voltage is sent to the LH and RH mirrors causing the mirrors to heat up. This also sends voltage to the rear defogger grid. For rear defogger description refer to Rear Window Defogger Description . The rear window defogger relay remains energized until the defog cycle is complete or the rear defogger switch is pressed a second time.

When the ignition switch is on and the rear defogger switch is pressed for the first time, the defog cycle lasts 10 minutes. However, further operation of the rear defogger will result in 5 minute defog cycles. The defog cycle is reset to 10 minutes when the ignition switch is turned off and back to on.

The defogger ON indicator is an LED that illuminates when the rear defogger and heated mirrors are on.
