BACKUP LAMPS
The backup lamps are located in the rear combination
lamps They will come on when the transaxle is shifted into
reverse. On a vehicle with an automatic transaxle, the
backup lamps are activated by the neutral safety backup
(NSBU) switch. On a vehicle with a manual transaxle, they
are activated by a reverse switch which is part of the trans-
axle.

181. Remove the trim panel from a 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 battery
negative terminal and one of the terminals in
the two–pin window motor connector.
2. Attach a fused jumper wire between the bat-
tery positive terminal and the remaining ter-
minal in the two–pin window motor connec-
tor. Unless the motor is at the end of its trav-
el, the window should move with the jumpers
attached.
3. To move the window in the opposite direc-
tion, reverse the jumper wire connections at
the window motor connector.
Does the power window operate in both direc-
tions when the motor is operated directly from
a battery?–Go to

201. Before reconnecting the two–pin window mo-
tor connector, connect an ohmmeter between
the terminals to check the resistance of the
motor.
2. Record the ohmmeter reading for motor re-
sistance.
3. Reconnect the motor connector and reinstall
the door trim panel.
4. Disconnect the electrical connector from the
dual power window switch.
5. At the dual power window switch connector,
use an ohmmeter to check the resistance
between the terminals which lead to the mo-
tor that was tested in Step 15
Is the resistance at the switch connector
approximately equal to the resistance that
was previously measured at the motor con-
nector?–Go to
