CIRCUIT OPERATION
When the Ignition Switch (X134) is in Position II,
voltage is suplied to the power mirrors circuit by
fuse F18.
Left/Right Movement
When a selected mirror is moved to the left by the
Mirror Adjustment Switch (X146) the internal
contacts move to the “Move Down or Left” and the
“Move Left” Positions. The Left/Right Motor of the
selected actuator is grounded at E200 through the
SW wires and the switch contacts. Voltage is
applied to the Left/Right Motor through the BP, BU
wires. The mirror now moves left.
When a selected mirror is moved to the right by the
Mirror Adjustment Switch (X146) the internal
contacts move to the “Move Up or Right” and the
“Move Right” positions. The Left/Right Motor of the
selected actuator is grounded at E200 through the
BU, BP wires and the switch contacts. Voltage is
applied to the Left/Right Motor through the SW
wires. Since the polarity of the voltage to the motor
has been reversed, the mirror now moves right.
Up/Down Movement
When a selected mirror is moved down by the
Mirror Adjustment Switch (X146) the internal
contacts move to the “Move Down or Left” and the
“Move Down” positions. The Up/Down Motor of the
selected actuator is grounded at E200 through the
SW wires and the switch contacts. Voltage is
applied to the Up/Down Motor through the BK, BN
wires. The mirror now moves down.
When a selected mirror is moved Up by the Mirror
Adjustment Switch (X146) the internal contacts
move to the “Move Up or Right” and the “Move Up”
positions. The Up/Down Motor of the selected
actuator is grounded at E200 through the BN, BK
wires and the switch contacts. Voltage is a applied
to the Up/Down Motor through the SW wires. Since
the polarity of the voltage to the motor has been
reversed, the mirror now moves up.
