DOOR MIRROR SWITCH ASSEMBLY
(CONTROL SWITCH, FOLDING
SWITCH
AND DEFOGGER SWITCH)
(FIG. 8-305)
The door mirror switch is made up of the control
switch that controls the vertical and horizontal move­
ment of both mirrors, the folding switch, and the
defogger switch.
The control switch consists of six switches, two of
which are used to select a mirror on either the left or
the right side, and the remaining four switches control
vertical or horizontal mirror movement.
The folding switch contains two switches, and their
contacts are changed over each time these switches
are depressed. The direction of the current flow to the
motor in the mirror is controlled to perform the fold­
ing and returning action of the mirror.
When depressing the defogger switch, the defogger
indicator lights up to inform the driver that the mirror
built-in heater is operating.

[!) INSPECTION
IL•I Check to see if there is any continuity between
the connector terminals while operating the
door mirror switch. (Fig. 8-306)
Repair or replace the switch when the result of
inspection is found abnormal.
