181. Remove the trim panel from the rear door
which has an inoperative power window.
2. Move a vehicle battery close enough to the
door so that the window motor can be pow-
ered directly from the battery with jumper
wires.
3. Disconnect the the two–pin window motor
connector in the door.
Important : To prevent the fuse in the jumper wire
from blowing, do not touch the jumper wires togeth-
er.
1. Attach a jumper wire between the negative
battery terminal and one of the terminals in
the two–pin window motor connector.
2. Attach a fused jumper wire between the posi-
tive battery terminal and the remaining termi-
nal in the two–pin power window motor con-
nector. Unless the motor is at the end of its
travel, the power window should move with
the jumpers attached.
3. To move the power window in the opposite
direction, reverse the jumper wire connec-
tions at the power window motor connector.
Does the power window operate in both direc-
tions when the motor is operated directly from
a battery?–Go to

19Replace the power window motor.
Is the repair complete?–System
OK–
201. Make sure the window lock on the main
switch is off.
2. Turn the ignition ON.
3. At the rear power window switch connector,
check the voltage at terminal 1.
Is the voltage equal to the specified value?11–14vGo to

Step 29
211. At the power window motor two–pin connec-
tor, use an ohmmeter to measure the resist-
ance of the power window motor. Record the
resistance.
2. Re–connect the two–pin power window motor
connector.
3. Disconnect the rear power window switch
connector.
4. Use an ohmmeter to measure between termi-
nals 2 and 6 of the rear power window switch
connector.
Is the resistance measured at the rear power
window switch connector equal to the resist-
ance previously measured at the rear power
window motor connector?–Go to

Step 22
22Repair the open circuit between the rear pow-
er window switch and the rear power window
motor connector.

StepActionValue(s)YesNo
1Check fuse F8.
Is either fuse blown?–Go to Step 2Go to Step 3
21. Check for a short circuit and repair it, if neces-
sary.
2. Replace the blown fuse.
Is the repair complete?–System OK–
31. Turn the ignition on.
2. Check the voltages at fuse F8.
Are both voltages equal to the specified value?11 – 14 vGo to Step 5Go to Step 4
4Repair the power supply to the fuse which did not in-
dicate battery voltage with the ignition on.
Is the repair complete?–System OK–
51. Disconnect the interior courtesy lamp/power
sunroof control switch connector.
2. Turn the ignition on.
3. Check the voltage at terminal 5 of the interior
courtesy lamp/power sunroof control switch
connector.
Is the voltage equal to the specified value?11–14 vGo to Step 7Go to Step 6
6Repair the open circuit between fuse F8 and the inte-
rior courtesy lamp/power sunroof control switch con-
nector.
Is the repair complete?–System OK–
71. Reconnect the interior courtesy lamp/power
sunroof control switch connector.
2. With the sunroof switch in the OPEN position,
check the voltage at terminal 4 of the interior
courtesy lamp/power sunroof control switch
connector.
3. With the sunroof switch in the CLOSE position,
check the voltage at terminal 6 of the interior
courtesy lamp/power sunroof control switch
connector.
Do both voltages equal the specified value?11 – 14 vGo to Step 9Go to Step 8
8Replace the interior courtesy lamp/power sunroof
control switch.
Is the repair complete?–System OK–
91. Disconnect the sunroof module connector.
2. With the sunroof switch in the OPEN position,
check the voltage at terminal 1 of the sunroof
module connector.
3. With the sunroof switch in the CLOSE position,
check the voltage at terminal 6 of the sunroof
module connector.
Are the voltages equal to the specified value?11–14 vGo to Step 11Go to Step 10
