How the Circuit Works
The two outside mirrors are controlled by the power
mirror switch. Each mirror has two reversible
motors: one motor moves lhe mirror uo and down
and the other motor moves the mirror left and right.
The power mirror switch contains four switches to
control mirror adjustment, and a switch lo select
the left or right mirror. With the ignition ON (ll),
battery voltage is supplied to the power mirror
switch. The mirror selector switch directs voltage
Irom the direction switches to either the left or rioht
mtrror.
Mirror Up
When you press the "up" edge of the mirror
adjustment button, voltage is supplied from one of
the UP switch contacts to both mirrors. With the
mirror select switch in the LEFT or RIGHT Dosition.
ground is provjded for the corresponding up/down
motor through the opposite UP switch contact.
Battery voltage is supplied to the mirror up/down
motor which then tilts the selected mirror uo.
Mirror Down
When you press the "down" edge of the mirror
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.
I,J
141-3
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.
Refer to the Service Manual (Section 23,
Body Electrical) for specific tests and
troubleshooting procedures.
