CIRCUIT OPERATION

CIRCUIT OPERATION
When the Ignition Switch (X134) is in position II,
voltage is supplied 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 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.
