Power Mirror

DESCRIPTION
All Eldorados and Sevilles are equipped with dual outside power mirrors that are adjusted from inside the car by moving the Power Mirror Switch in the desired direction.

Each outside mirror has two reversible motors. One motor adjusts the mirror view left and right and the other motor adjusts the mirror up and down. the driver operates either an up-down switch or a left-right switch to control the polarity of the voltage applied to the mirrors. The Mirror Select Switch, which is part of the Power Mirror Switch, directs the applied voltage from the fuse to either the LH or RH Outside Mirror Assembly.

CIRCUIT OPERATION

Up-Down Operation
With the Mirror Select Switch in the LH position and the Up-Down Switch in the up position, battery voltage from Fuse C5 is applied to the LH Outside Mirror Assembly's UP-DN Motor through circuit 88 and the Up contacts of the mirror control switch. The LH Outside Mirror Assembly's UP-DN Motor's ground path is applied through circuit 89, the Mirror Select Switch, the UP contacts of the Power Mirror Switch and circuit 804. the UP-DN Motor runs and turns the mirror up.

When the Up-Down Switch is moved to the down position, the voltage polarity to the UP-DN Motor is reversed. The motor is now grounded through circuit 88 and the Power Mirror Switch and voltage is applied to the motor through circuit 89. The motor will now turn in the opposite direction and move the mirror down.

Left-Right Operation
The L-R Motor operation is similar to the Up-Dn Motor operation. When the Left-Right Switch is in the left position, battery voltage from Fuse C5 is applied to the LH Outside Mirror Assembly's L-R motor through circuit 82 and the left contacts of the mirror control switch. The LH Outside Mirror Assembly's L-R Motor's ground path is applied through circuit 81, the Mirror Select Switch, the left contacts of the Power Mirror Switch and circuit 804. The L-R Motor now runs and turns the mirror to the left.

If the Left-Right Switch is pushed to the Right position, the same motor has power applied to it but the polarity is reversed at the motors terminals. This causes the motor to run in the opposite direction moving the mirror to the right.

The RH Outside Mirror works the same way as the LH Outside Mirror when the Mirror Select Switch is moved to the right position.
