Moonroof (cont'd)
- How the Circuit Works
Moonroof Open
When you push the moonroof switch to the OPEN
position, the moonroof open switch applies ground
to the moonroof "open" relay through the YEL wire.
The moonroof "open" relay applies battery voltage
to the moonroof motor through the GRN/RED wire.
The moonroof "close" relay supplies ground to the
moonroof motor through its normally closed relay
conlacls. When the moonroof moves out of the fully
closed oosition. the tilvclose switch moves to the
OPEN position; the open/close switch moves to the
OPEN oosition.
Moonrool Tilt
When you push the moonroof switch to the TILT
position, the moonroot tilt switch applies ground to
the moonroof "close" relay through the BLU wire,
tilvclose switch and RED wire. The moonroof"close" relay applies battery voltage to the
GRNff EL wire to the moonroof motor. The
moonroof "open" relay supplies ground to the
moonroof motor through its normally closed relay
contacts. When the moonroof is in the tilt oosition,
the trlvclose switch moves to the TILTED position;
the open/close switch moves to the TILTED
Dosition.
Moonroof Close trom the Open Position
When you push the moonroof switch to the CLOSE
position, the moonroof "close" switch applies ground
to the moonroof "close" relay through the YEURED
wire, tilvclose switch and GRN/RED.wire. The
moonroof "close" relay applies battery voltage to the
GRNI/EL wire to the moonroof motor. The
moonroof "open" relay suppfies ground to the
moonroof motor through its normally closed relay
contacts. When the moonroof is fully closed, the
tilvclose switch moves to the closed position; the
open/close switch moves to the CLOSED position.
122-2
Moonroot Close from the Tilt Position
When you push the moonroof switch to the CLOSE
posilion, the moonroof "open" switch applies ground
to the moonroof "close" relay through the YEURED
wire, open/close switch and moonroof "open" relay.
The moonroof "open" relay applies battery voltage to
the moonroof motor through the GRN/RED wire. The
moonroof "close" relay supplies ground to the
moonroof motor through its normally closed relay
contacts. When the moonroof is fully closed, the
tilvclose switch moves to the closed oosition and the
open/close switch moves to the CLOSED position.

How the Circuit Works
The two outside mirrors are controlled by the power
mirror switch. Each mirror has two reversible
motors: one motor moves the mirror up and down
and the other motor moves the mirror lett and right.
The power mirror switch contains four switches to
control mirror adjustment, and two switches to
select the left or right mirror With the ignition in ON
(ll), battery voltage is supplied to the power mirror
swrtch. The mirror selector switch directs voltage
from two of the direction switches to either the left
or the right mirror.
Mirror Up
When you press the "up" edge of the mirror
adjustment button, ground is supplied from one of
the up/down switch contacts to both mirrors; battery
voltage is supplied from the opposite up/down
switch contact through the mirror select switch. lf
the mirror select switch is in the left or right position,
battery voltage is supplied to the corresponding
mirror uo/down motor which then tilts the selected
mtrror uD.
Mirror Down
When you press the "down" edge of the mirror
adjustment button, battery voltage is supplied Irom
one of the up/down swilch contacts to both mirrors;
a ground is supplied from the opposite up/down
switch contact through the mirror select switch. lf
the mirror select switch is in the left or right position,
battery voltage is supplied to the corresponding
mirror up/down motor which then tilts the selected
mrrror oown.
Mirror Left
When you press the "|eft" edge of the mirror
adjustment button, battery voltage is supplied from
one of the lefuright switch contacts to both mirrors;
a ground is supplied from the opposite lefuright
switch contact through the mirror select switch. lf
the mirror select switch is in the left or right position,
battery voltage is supplied to the corresponding
mirror lefvright motor which then tilts the selected
mirror to the lett.
Mirror Right
When you press the "right" edge of the mirror
adjustment button, ground is supplied from one of
the lefvright switch contacts to both mirrors; battery
voltage is supplied from the opposite left/right switch
contact through the mirror select switch. lf the mirror
select switch is in the left or right position, battery
voltage is supplied to the corresponding mirror
lefuright motor which then tilts the selected mirror to
the right.

adjustment button, ground is provided through one
of the DOWN switch contacts to both mirrors.
With the mirror select switch in the LEFT or RIGHT
position, voltage is supplied to the corresponding
up/down motor through the opposite DOWN switch
contact. Battery voltage is supplied to the mirror
up/down motor which then tilts the selected
mtrror down.
Mirror Left
When the mirror select switch is in the LEFT or
RIGHT position, and you press the "lett" edge of the
mirror adjustment button, voltage is supplied to both
corresponding mirror motors through one of the
LEFT switch contacts. Ground is provided for the
corresponding lefvright motor through the opposite
LEFT switch contact, 8attery voltage is supplied to
the mirror left /right motor which then tilts the
selected mirror left.

Mirror Right
When the mirror select switch is in the LEFT or
RIGHT position, and you press the '?ight" edge of
the mirror adjustment button, ground is provided to
both corresponding mirror motors through one of
the RIGHT switch contacts. Voltage is supplied to
the corresponding leruright motor through the
opposite RIGHT switch contact. Battery voltage is
supplied to the mirror left /right motor which then
tilts the selected mirror right.
Mirror Detoggers
With the ignition switch in ON (ll), battery voltage is
supplied to the mirror defogger switch. When you
press the mirror defogger switch ON, voltage is
supplied to both mirror defoggers, causing them to
heat up and remove any fog from the mirrors. The
opposite side of each defogger grid is connected to
g rou no.
