System with Only Front Power Windows, One or Both Windows Are Inoperative

CAUTIONWhen 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.

Waterleak Repair

Some waterleaks around the glass can be repaired without removing the glass.

Note. This type of repair may be used only for urethane-installed glass.

  1. Remove the reveal molding in the area of the leak. It may be necessary to remove the garnish molding or the trim strip lace in order to locate the leak.
  2. While spraying water over the leak area, carefully push the glass outward in order to determine the size of the leak.
  3. Mark the location of the leak.
  4. Use water to clean any dirt from the area. Dry the area with an air hose.
  5. Using a sharp knife, trim off the uneven edges of the adhesive caulking material around the leak for a distance of 75 - 100 mm (3 - 4 in.) on both sides of the leak.
  6. Using a sharp knife, trim off the uneven edges of the adhesive material around the leak 75 - 100 mm (3 - 4 in.) on both sides of the leak.
  7. Prime the trimmed area with the primer.
  8. Allow the primer to dry for 5 minutes.
  9. Apply the adhesive over the leak and for a distance of 75 - 100 mm (3 - 4 in.) on both sides of the leak.
  10. Immediately after applying the adhesive, use a flat stick or a similar tool to work the adhesive into the leak area and into the joint between the original material and the vehicle body in order to ensure a watertight seal.
  11. Spray warm or hot water over the repaired area in order to determine if the leak was repaired. Do not run a heavy stream of water directly on the freshly applied adhesive.
  12. Install the trim strip lace if it was removed.
  13. Install the garnish molding if it was removed.
  14. Install the reveal molding.

Windnoise Repair

Windnoise leak repairs are very similar to waterleak repairs. Refer to Waterleak Repair . The actual procedure depends on the type of seal being repaired.

Leaks around the door opening weatherstrips do not always indicate a faulty weatherstrip. A door or window adjustment may resolve the condition. Refer to Windshield Removal and Installation or DOOR ASSEMBLY REMOVAL AND INSTALLATION .

Rear Window Defogger Braided Lead Wire Repair

The rear window defogger bus lead wire or the terminal can be reattached by resoldering. Use a solder containing 3% silver and a rosin flux paste.

Scheme 43

Scheme 43: Rear Window Defogger Braided Lead Wire Repair
  1. The repair area should be buffed with fine steel wool before soldering the bus lead wire.
  2. Apply the paste-type rosin flux in small quantities to the wire lead and the bus lead wire repair area using a brush.
  3. Coat the soldering iron tip with solder. Use only enough solder to ensure a complete repair.
  4. Use only enough heat to melt the solder. Do not overheat the wire when resoldering to the bus lead wire.

Scheme 44: Removal
  1. Remove the door seal trim. Refer to «DOOR SEAL TRIM REMOVAL AND INSTALLATION»(ref-257113-S30781810252007062900000) .
  2. Remove the outside channel molding. Refer to «OUTSIDE CHANNEL MOLDING REMOVAL AND INSTALLATION»(ref-257113-S09191317892007062900000) .
  3. Remove the screws that secure the glass to the window regulator.
  4. Remove the glass from the door.
