Door Switch
Terminal Block
Fig. 16-131 Checking for Current at Door Window Switch
b. Checking Feed Circuit Continuity
at Window Control Switch
1. Connect one light tester lead to feed terminal
of switch block and ground other tester lead to
body metal, Fig. 16-131.
2. If tester does not light, there is an open or
short circuit between switch and power source.
c. Checking Window Control Switch
1. Insert one end of a #12 gage jumper wire to
the switch feed terminal and other end to one of
the motor lead terminals in the switch block.
Repeat this check on remaining motor lead ter-
minal, Fig. 16-132.
2. If motor operates with jumper wire, but does
not operate with switch, switch is defective.
Fig. 16-133 Checking Between Switch and Motor
2. Insert one end of a #12 gage jumper wire to
switch feed terminal and the other end to one of
the m o t o r lead terminals in switch block,
Fig. 16-132.
3. With light tester check for current at ter-
minal being checked. If tester does not light,
there is an open or short circuit in harness be-
tween control switch and m o t o r connector,
Fig. 16-133.
e. Checking Door Window Motor
1. Check window regulator and channels for
possible mechanical bind of window.
d. Checking Wires Between Door Window
Switch and Door Window Motor
1. Disengage harness connector from window
motor connector. The thumb release on harness
connector must be depressed before it can be
disengaged from the motor.
2. Check attachment of window motor to inner
panel to insure an effective ground.
3. Connect one end of a #12 gage jumper wire
to power source and the other end to one of the
terminals on window motor.

4. If motor fails to operate with a jumper wire,
the motor is defective and should be repaired
or replaced as required. Check the other motor
lead in same manner.
98. Typical Failures of Power Window
The following typical failures and corrections
have been listed as an aid for eliminating elec-
trical failures in the power window electrical
circuit. It should be noted that multiple failures
in the circuit may lead to a combination of con-
ditions, each of which must be checked sepa-
rately. See circuit diagram shown in Fig. 16-134.
