Outside Mirrors Circuit

Each power mirror has 2 reversible motors. One motor adjusts the mirror view left and right. The other motor adjusts the mirror up and down. First the driver must select which mirror is to be moved by placing the mirror select switch in either the LEFT MIRROR position or the RIGHT MIRROR position. The driver then operates the mirror switch in one of the following positions in order to control the polarity of the battery voltage applied to the mirrors:
^ UP
^ DOWN
^ LEFT
^ RIGHT

The battery voltage is applied from the engine compartment fuse relay MIRROR fuse to either the left or right power mirror. As the mirror is operated, the battery voltage is supplied through the contacts of that direction to the motor. The motor is grounded through the contacts of the opposite direction.

The memory mirrors are controlled by the Memory Mirror Module (MMM). The MMM controls the movement of the 4 mirror motors: 2 motors for the left mirror and 2 motors for the right mirror. All of the motors operate independently of each other. Each motor has an attached position sensor.

The engine compartment fuse/relay center MIRROR fuse supplies the battery positive voltage (B+) via CKT 1740 (ORN) in order to power the MMM and the mirror motors. Ground for the MMM is provided via CKT 151 (BLK) to G205.
