1988 Power Mirrors
JEEP
DESCRIPTION
Outside power rear view mirrors consist of door-mounted
mirrors with internal motor drive and backing plate. The Ford
electronic day/night mirror will change from normal to non-glare
position when glare reaches mirror. The non-glare functions only at
night.
TESTING
Mirror Motors & Switches
1) Ensure fuse is okay by operating interior lights. If
neither mirror operates, check for battery voltage at power mirror
switch assembly. Connect a voltmeter between terminal "G" (Red with
White stripe) and ground. If battery voltage is present, connect
voltmeter between terminals "G" and "F" (Black). If battery voltage is\
not present, check circuit at Red with White stripe wire and Black
wire.
2) If one mirror does not operate, connect a voltmeter across
power mirror switch assembly terminals. See Fig. 1. Voltage will be
present when control switch and mirror select switch are operated for
that motor.

3) If voltage is present but mirror does not operate, check
motor and wiring. If voltage is not present when 2 switches are on,
