Outside Mirror Description and Operation
Power Mirror System Components
The power mirror system consists of the following
components:
• |
Outside rearview mirror
switch |
• |
Driver outside rearview
mirror |
• |
Passenger outside rearview
mirror |
Each of the outside rearview mirror contains two motors. The
vertical motor operates the mirror in the up and down directions,
and the horizontal motor operates the mirror in the left and right
directions.
Power Mirror System Controls
The outside rearview mirror switch is a four position
directional switch: Up, Down, Left and Right.
The mirror select switch is a three position switch: left,
neutral/fold, and right.
Power Mirror System Operation
The outside rearview mirror switch receives battery voltage from
the underhood fuse block The power mirror switch also receives a
constant ground.
The four positions of the direction switch have dual switch
contacts. Each of the contacts are connected to opposing sides of
the appropriate power mirror motors through the selector switch.
The selector switch completes these circuits depending on the
position of the selector switch, L or R.
If the selector switch is placed in the L position and the up
switch is pressed, battery voltage will be supplied to the left
outside rearview mirror vertical motor through the left mirror
motor vertical control circuit and ground through the left mirror
motor common control circuit. If the down switch is pressed,
battery voltage will be supplied to the left outside rearview
mirror vertical motor through the left mirror motor common control
circuit and ground through the left mirror motor vertical control
circuit.
The remainder of the mirror functions operate in the same manner
as described above. Placing the power mirror switch in opposing
positions, left/right or up/down, will reverse the polarity to the
mirror motor, reversing the direction of movement.
Folding Mirrors (If Equipped)
The folding mirror system is controlled through an electronic
switch that can be activated when the mirror select switch is in
the neutral position. When the mirror select switch is in the
neutral position, the fold/retract function is activated by
pressing the down arrow. The fold/retract switch will fold or
retract the mirrors depending on their current state. When a power
fold or retract function is activated, battery voltage is supplied
to the fold motor by the appropriate fold or retract control
circuit and the motor will be grounded by the opposite control
circuit.
Heated Mirrors (If Equipped)
The heated mirrors are controlled through the rear defog relay.
Whenever the rear window defogger is turned on battery voltage is
supplied to the mirror heater elements through the left and right
mirror heater element control circuits.
