It is easy to replace a window
lift motor. However, you must take proper precautions to assure
a safe, trouble free installation. Park the vehicle in a level,
well ventilated area. Set the parking brake to avoid inadvertent
movement. There must be enough room to fully open the doors for
easy access to the window regulator and window lift motor.
CAUTION: If the vehicle is equipped with a seat belt
(safety belt) system which is attached to the door, refer to a
suitable repair manual to make sure you have the tools, skill
and knowledge to remove and correctly install such systems. If
you do not, then seek the services of a professional technician.
|
REMOVING THE ORIGINAL
WINDOW LIFT MOTOR:
|
1. Make sure the power to operate the door
locks, window lift motors and radio speakers or other electrical
devices is off to prevent personal injury, short circuits or
other damage.
2.Carefully remove interior door handles and trim which might
interfere with removing the inner door trim panel.
3. Remove any screws which secure the inner trim panel to the
door. Such screws are often hidden by carpeting at the lower
area of the panel, behind arm rest, concealed by plastic cover
plugs or assist grips. |
 |
4. Working carefully to avoid
visible damage to painted surfaces use a thin, broad, flat tool
such as a gasket scraper or stiff putty knife to release
fasteners which hold the trim panel to the door. Work close to
each fastener to avoid damage to the trim panel.
5. Lift the trim panel off of the door observing any retaining
tabs on the back of the panel which may be inserted in slots in
the door. Also take special care to avoid damage to any wires or
switches which may be attached to the trim panel. Unplug the
wires and/or remove switches as required.
6. Carefully peel off the plastic waterproofing membrane used to
seal all of the openings exposed when the panel is removed. This
membrane must be installed intact during the final stages of
replacing the window lift motor. |
7. Using a wax crayon, marking pen or
similar method, mark the exact location of the window regulator
mechanism where it is bolted or riveted to the door.
NOTE: Unless the regulator can be reinstalled at its
exact location you will have to align and adjust the mechanism.
If the regulator uses a sector gear and levers to move the glass
continue with Step 8. However, if it uses cables or a plastic
tape with gear teeth on it go to the instructions for "REMOVING
& INSTALLING TAPE - TYPE REGULATORS". |
 |
| 8. Inspect regulator to
determine if its arm will readily slide off the track on the
glass to permit removal of the regulator assembly or if it
should be disconnected from the glass by removing fasteners from
the glass. If possible, operate the regulator to lower the glass
to a location where the tracks or fasteners on the glass can be
reached through one of the openings in the inner door panel. |
9. Using duct tape, secure the glass to the
door frame so that it will not move or drop when it is
disconnected from the regulator.
NOTE: If the regulator cannot be operated to position the
glass to a convenient location, it will be necessary to lower
the glass along with the regulator within the door to a position
where the glass can be separated from the regulator. |
 |
10. Make sure the power window
circuit is turned off (ignition switch OFF, fuse removed from
the circuit). Disconnect the window lift motor electrical
connector within the door.
11. Unbolt the regulator mechanism from the glass on vehicles so
equipped. If glass has not been taped in position (as shown in
Step 9), raise the glass to about mid-position and use duct tape
to secure it there.
12. While supporting the mechanism, remove all fasteners which
hold the regulator and window lift motor assembly in the door.
CAUTION: DO NOT attempt to remove the window lift motor
from the regulator within the door as this would release the
spring-loaded arm possibly causing severe personal injury and/or
mechanical damage. |
 |
13. Remove the regulator and motor assembly
through the appropriate access opening in the inner door panel.
Disconnect motor breather tube if so equipped.
14. Using a "C" clamp, securely clamp the sector gear
to the regulator frame.
If the gear cannot be clamped, drill a ¼ inch hole through the
sector gear and the regulator frame. DO NOT drill close
to the gear teeth or other critical places. Insert a ¼ inch
bolt through the drilled hole and tighten a nut on the bolt to
lock the sector gear and regulator arm from moving.
15. Remove the three bolts which attach the window lift motor to
the regulator and remove the motor from the regulator. |
 |
 |
INSTALLING THE
REPLACEMENT WINDOW LIFT MOTOR:
|
| 1. If necessary, transfer the
wiring harness connector from the original motor to the
replacement unit. Use two crimpon splices to make the
connections. |
Be careful to match the colors of the wires
before crimping the splices.
2. Put the original window lift motor in the replacement
unit’s carton to assure proper core credit upon return.
3. Position the replacement window lift motor on the regulator
and loosely install the three mounting screws. Make sure the
gear on the motor engages the sector gear on the regulator with
a small working clearance. |
 |
 |
4. Evenly tighten the motor mounting
screws. Remove the safety bolt previously installed in the
sector gear. Make sure the motor is flat against the regulator
and that a small working clearance remains between the gears.
5. Apply a small amount of high quality grease to all gears and
sliding parts of the regulator. A drop of oil should be applied
to each pivot point. |
6. Work with the motor and regulator
assembly through the access opening in the inner door panel and
move it into approximate position while engaging the regulator
with the door glass lower track where appropriate.
7. Install but do not tighten all of the fasteners that mount
the window lift motor and regulator assembly in the door.
8. Position the regulator assembly so that the alignment marks
made in removal Step 7 are exactly matched. Then tighten the
fasteners securely. |
 |
| 9. If the glass is secured to
the regulator by means of fasteners, lower the glass if
necessary (after removing the duct tape) and install the
regulator to glass fasteners. Make sure that any spacers or
other insulating parts are re-installed when re-attaching the
glass. |
 |
10. Connect the wiring
connector on the motor to the wiring harness in the door.
Connect motor breather tube if so equipped.
11. Install the fuse if previously removed and turn on the
ignition to permit operation of the window lift motor. |
 |
12. Test the operation of the
motor. If it fails to move in the correct direction, reverse the
two motor wires. Then verify correct operation.
13. Power the window to the full up and full down positions.
Make sure that the glass moves easily without binding or
sticking.
IF THE MOTOR IS DAMAGED DUE TO OVERLOAD
RESULTING FROM A BINDING WINDOW THE WARRANTY IS VOID. |
 |
14. Make sure the glass is correctly
aligned in both the full up and full down positions. Also make
sure that any stops provided to control the up or down limits of
glass travel are correctly positioned.
15. Install the plastic membrane over all openings in the inner
door panel. If necessary apply a small amount of trim adhesive
to hold the membrane securely in place.
16. Reconnect any disconnected wires and switches. Install the
door trim panel and any hardware previously removed.
NOTE: If window lift system fails to work correctly,
refer to the troubleshooting chart.

6. Remove fasteners which attach the door glass to the vertical
slide on the regulator.
7. Remove the fasteners which attach the regulator and vertical
slide to the door panel. |
8. Remove fasteners which secure the window
lift motor to the door panel. Support the motor to avoid bending
or damaging the cable/tape housing between the motor/gearbox
assembly and the vertical slide.
9. Remove the motor and regulator assembly through the
appropriate opening in the inner door panel. Use great care to
avoid bending the housing parts which connect the motor/gearbox
assembly to the vertical slide(s). |
 |
| 10. Remove fasteners which
attach the window lift motor to the gearbox. Remove the motor
from the gearbox while watching for any thrust washers or
bearings located at the inner end of the worn gear on motors so
equipped. Save these parts for use on the replacement motor.
