Mirrors: Description and Operation

The Power Mirror System has voltage applied from the PWR ACCY Fuse 7 to the Power Mirror Switch. Each Outside Mirror has two reversible motors. One adjusts the mirror up and down, and the other adjusts the mirror right and left. These motors are controlled by the Power Mirror Switch. The Mirror Position Switch controls the polarity of the voltage to the motors. The Power Mirror Switch also contains a Mirror Select Switch, which directs the voltage to either the RH or LH Outside Mirror.

The Power Mirror Switch receives battery voltage from the PWR ACCY Fuse 7 through CKT 640 and is permanently grounded at G200. When the LH Outside Mirror is selected, the Mirror Position Switch will control the motors of the LH Outside Mirror. When the Mirror Position Switch UP position is selected, voltage is applied to the Up/Down Motor of the LH Outside Mirror through CKT 88. Ground will he provided to the Up/Down Motor by the Outside Mirror Switch through CKT 82 (Chevrolet) or CKT 89 (Pontiac). The Up/Down Motor in the LH Outside Mirror will run and turn the LH Outside Mirror up. When the Mirror Position Switch DOWN position is selected, voltage is applied to the Up/Down Motor of the LH Outside Mirror through CKT 82 (Chevrolet) or CKT 89 (Pontiac), and ground is provided through CKT 88. This will cause the Up/Down Motor to rotate in the opposite direction and turn the LH Outside Mirror down. The Left/Right Motor of the LH Outside Mirror operates in a similar manner. When the Mirror Position Switch LEFT position is selected, voltage is applied to the Left/Right Motor of the LH Outside Mirror through the CKT 81. Ground will he provided to the Left/Right Motor by the Outside Mirror Switch through CKT 82. The Left/Right Motor will run and turn the LH Outside Mirror to the left. When the Mirror Position Switch RIGHT position is selected, voltage is applied to the Left/Right Motor of the LH Outside Mirror through the CKT 82 and ground is provided through CKT 81. This will cause the Left/Right Motor to rotate in the opposite direction and turn the LH Outside Mirror to the right.

The RH Outside Mirror is adjusted in the same way when the Mirror Select Switch is moved to the RH position, and the appropriate position switch is operated.
