are Inoperative
CAUTION : When powering the window motors directly from a battery with jumper wires, make sure one of the
jumper wires contains a fuse. If the jumpers are accidentally touched together, the fuse will prevent sparking
and burns from sudden terminal heating.

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.

tions when the motor is operated directly from
a battery?–Go to

sistance.
3. Reconnect the motor connector and reinstall
the door trim panel.
4. Disconnect the electrical connector from the
dual power window switch.
