DESCRIPTION AND OPERATION
Glass, Frames and Mechanisms
Vehicles may be fitted with front power operated
windows (rear windows manually operated) or both
front and rear power operated windows.
Front only Power Windows
The switches located on the front door trims are used
to raise/lower the front windows. Depress and hold
the up/down switch locations to raise and lower the
window.
Front and Rear Power Windows
The five switches, located on the front driver door
trim, control the four windows. Switches are also
provided on the other three door trims for operation of
that window only. The child lock switch on the front
driver door can be used to disable the rear switches.
Auto down - the driver’s window switch can be
pressed and held for approximately 1 second to
automatically fully lower the driver’s window.
All electric windows operate with the ignition switch in
the ‘ON’ or ‘accessory’ positions. When the key is
returned to the ‘OFF’ position, power window
operation is available for one hour (or 45 seconds if a
door is opened).

does not move, the glass coupling or gear teeth
have failed.
5. If the motor does not run, disconnect the wires at
the motor in order to check for voltage attach feed
wire while actuating the window switch. If there is
no voltage at the motorfeed terminals, check for
voltage at the switch feed wire. If there is voltage
at the switch, replace the switch.
Window inoperative in one direction
6. Check the operation with the individual and
master switches. If only one switch is inoperative,
replace the faulty switch.
7. If the window will not function correctly from either
switch, check for defective wiring between the
switch and the motor. If the wiring leads are open,
replace the wiring.
8. If the window operates normally in one direction,
the motor is not defective.
Power window operates sluggishly
9. Check the regulator and window runs for binding.
Adjust the runs, repair and lubricate the regulator.
Lubricate the runs with silicone lubricant.
10. Check for frayed insulation where the window
wires may partially ground. Check for loose
connections which will cause high resistance.
11. Check motor current draw during operation (place
an ammeter in series with the ground lead of the
battery). Motor current draw should not exceed 12
amps during normal operation and should exceed
20 amps at stall. If the current is above 12 amps
during operations of the window, readjust the
glass mechanism. If the stall current is below 20
amperes at stall, look for poor electrical
connections.
12. Motor current draw when disconnected from the
regulator plate should not exceed 5 amps.
