GENERAL INFORMATION
Front and rear door window lift motors are of the
permanent magnet type. A positive and battery nega-
tive connection to either of the two motor terminals
will cause the motor to rotate in one direction. Re-
versing current through these same two connections
will cause the motor to rotate in the opposite direc-
tion.
Each individual motor is grounded through the
master switch by a black wire attached to the left
cowl panel.
WIRING VOLTAGE TEST
The following wiring test determines whether or not
voltage is continuous through the body harness to
switch.
After removing switch for testing purposes, care-
fully separate multiple terminal block on wiring har-
ness from switch body. Ignition switch in the ON
position, connect one lead of test light to black (or
gray) wire terminal and touch other test light lead to
tan wire terminal. If the test light comes on, the
wiring circuit between the battery and switch is func-
tional. If light does not come on, check 30 amp main
fuse (circuit breaker) or for a broken wire. For wiring,
specific connector type and location, refer to Group
8W, Wiring Diagrams.
WINDOW LIFT SWITCH TEST
For switch testing, remove the switch from its
mounting, refer to Switch Removal. Using an ohmme-
ter, refer to Window Switch Continuity Charts to
determine if continuity is correct (Fig. 1 and 2). If the
results are not obtained, replace the switch.
The master window switches has a Auto-Down fea-
ture. Actuation of the master switch to the second
down position will move the drivers side window com-
pletely down. The electronic switch will automatically
disconnect the motor approximately 1 second after
the window bottoms out. Failure of the electron
switch to detect stall current, will cause the switch to
disconnect after approximately 13 seconds. The auto
down function can be canceled by any movement of
the switch.
