1. GENERAL I NFORMATION
Electrically adjustable exterior rear-view mirrors are fitted as standard equipment on all VY Series Models.
Each exterior mirror assem bly has two reversible m otors: one to tilt the mirror face up and down (vertical position)
and one to tilt the mirror face left and right (horizontal position).
The ex terior rear-view m irrors are adjusted electr ically from ins ide the vehicle using the mirror control switch, whic h
is mounted in the driver’s door pull-handle.
Replacement exterior rear-view mirror assemblies are available in Black. These are made of acrylate styrene
acrylonitrile (ASA) plastic. Replacement assemblies requiring a colour-coded contrast need to be masked and
painted using correct refinishing procedures as outlined by the paint manufacturer.
The interior rear-view mirror is manually adjusted to suit the driving position. Models fitted with production option
UE1 (Comm unication System Te lem atics) have som e c om ponents of this system installed into the rear-view mirror.
Refer to Section 12K, TELEMATICS for service information relating to the interior rear-view mirror of these models.

1.1 INTERIOR MIRROR OPERATION
For vehicle models fitted with production option UE1 (Communication System Telematics), refer to
Section 12K, TELEMATICS.
DAY/NIGHT SETTING
A lever is fitted at the base of the interior rear-view
mirror. When the lever is pulled to the forward
position, the fac e of the m ir ror tilts slightly upwar ds.
This maintains rear vision but reduces the glare of
reflected light for night-time driving. The lever
should be reset to the rearward position for all
daytime driving.
Figure 12H-2
1.2 CONTROL SWITCH OPERATION
The exterior-mirror control switch has two controls:
a slide-select switch (1) (with left mirror and right
mirror positions) and a directional toggle switch (2)
to control the direction of adjustment.
The dire ctional toggle switch is designed to operate
in only one direction at a time and is activated by
pressing the edge of the toggle in the required
direction.
Figure 12H-3
TILT DOWNWARDS
With the switches positioned as shown in
Figure 12H-4, the LH exterior mirr or is selected and
the toggle switch is set to activate the vertical
position motor to tilt the mirror DOWNWARDS.
The following circuit is activated.
Battery voltage is supplied to the toggle switch
contacts via fuse F15. This voltage is applied via
circuit 330 (Brown wire) to one side of the vertical
position motor. The circuit is completed on the
other s ide of the LH ver tic al pos ition motor, with the
following path to ground:
• through circuit 89 (Grey wire)
• to the LH side select-switch contacts
• through the toggle switch directional contacts
and
• circuit 650 (Black / Blue wire) to ground.
This activates the vertical position motor until the
directional toggle switch is released.
TILT UPWARDS
When the toggle switch is pressed to move the
mirror UPWARDS, it switches the circuit so that
voltage is applied to the same motor, but in the
opposite direction.
That is, from fuse F15 to the toggle switch then
through the select s witch c ontacts and via c irc uit 89
to the motor.
The path to ground is now via circuit 330 to the
toggle switch contacts, then through circuit 650 to
ground.
Figure 12H-4
TILT OUTWARDS
When the directional switch is pressed in the
OUTWARD position, the circuit in Figure 12H-5 is
activated as follows:
Battery voltage from fuse F15 is supplied through
the directional centre contacts of the toggle switch
and circuit 330 (Brown wire) to one side of the
horizontal mirror motor.
The LH mirror horizontal position motor has a path
to ground through:
• circuit 82 (Purple wire)
• the LH side select switch contacts
• the directional contacts
• circuit 650 (Black / Blue wire) to ground.
This energises the LH m irror horizontal m otor to tilt
the mirror OUTWARDS until the toggle switch is
released.
TILT INWA RDS
W hen the directional toggle switch is pressed to tilt
the mirror INWARDS, the LH mirror horizontal
motor is supplied voltage in the opposite direction.
Power to the motor is supplied through the
directional and LH side select switch c ontacts, then
through circuit 82 (Purple wire). The motor is
grounded though circuit 330 (Brown wire) and the
directional switch c ontacts, then through circuit 650
(Black / Blue wire).
LH vs. RH MIRROR OPERATION
The RH motors operate by the same principles as
the LH motors (outlined previously).
By moving the side-select switch to adjust the RH
side mirror, power and ground connections are
made as for the LH side, but using different wires
(different circuit numbers).
To tilt the RH mirror DOW N, power is supplied via
circuit 889 (Light Blue wire) and grounded via
circuits 330 (Brown wire) and 650 (Black wire).
To tilt the RH m irror UP, power is supplied through
circuit 330 and grounded via circuits 889 and 650.
To tilt the RH mirror OUT, power is supplied
through circuit 90 and grounded via circuits 330
and 650.
To tilt the RH mirror IN, power is supplied through
circuit 330 and grounded via circuits 90 and 650.

2. SERVICE OPERATIONS
IMPORTANT
All fasteners are important attaching parts as they affect the performance of components and failure
could result in major repair. Where specified in this section, fasteners MUST be replaced with parts of
the same part number or a GM approved equivalent. Do not use fasteners of an inferior quality or
substitute des ign.
Torque values must be used as specified during reassembly to ensure proper retention of the
components.
Throughout this section, fastener torque specifications may be accompanied by the following
identification marks:
