General Tech Tips

• Use painter’s tape rather than duct tape to secure the window. It will not damage paint or leave a sticky residue.
• A plastic pry tool is useful. It will not easily damage delicate trim like a screwdriver or metal pry bar.
• The replacement regulator should have a liberal amount of grease on slide area. If there is not much grease present, white lithium grease works well to lubricate the slide area.
• Aftermarket window tinting can cause the window to travel slower and put additional strain on the window regulator assembly.
• Window run channels should be cleaned and lubricated before the installation of a new window regulator assembly. Silicone spray works well.

INSTALL/REMOVAL INSTRUCTIONS: WINDOW LIFT MOTOR

Removal Instructions

• STEP 1: Using a trim panel removal tool, remove the plastic interior door trim panel retainer.

• STEP 2: Using a trim panel removal tool, place the tool between the interior door trim panel and the power switch bezel assembly and gently pry to release the bezel assembly.

• STEP 3: Using a Phillips head screwdriver, remove the master power switch assembly.

  • STEP 3a: Disconnect the power mirror switch assembly.
    NOTE: Not all vehicles are equipped with this option.

• STEP 4: Using a Phillips head screwdriver, remove the interior door trim retaining screw.

• STEP 5: Using a trim panel removal tool, place the tool between the interior door trim panel and the door and gently pry the panel so that you can place your fingers between the interior door trim panel and the door. At this point, you should be able to lift the interior door trim panel in an upward motion while at the same time pulling toward you. There are NO interior door trim panel retaining clips. This is an interference interior door trim panel, meaning that there are key positions in the door to align the interior door trim panel.

• STEP 6: Once the interior door trim panel has been removed, use your interior trim removal tool to disconnect the door wiring sub-harness.

• STEP 7: Once the door wiring sub-harness has been disconnected from the door, partially remove the water vapour barrier.
  NOTE: It is not necessary to completely remove the water vapour. You will be able to access the window lift motor connector without removing the entire water vapour barrier.

• STEP 8: Using your power window switch, lower the window glass to expose the door glass mounting rivets.

• STEP 9: Once the window regulator has been lowered (exposing the window glass attaching rivets), attach your 1/8” drill bit to your drill to remove the centre of the rivet. Once you have finished this step, go up to a 3/8” drill bit and repeat the process. Your goal is to remove the rivet head. It may be necessary to go up to a 1/2” drill bit to remove the rivet head.
  CAUTION: USE EXTREME CAUTION WHILE PERFORMING THIS STEP. FAILURE TO DO SO WILL RESULT IN GLASS BREAKAGE. YOUR MAIN OBJECTIVE IS ONLY TO REMOVE THE RIVET HEAD. DO NOT DRILL THROUGH THE RIVET, OR YOU WILL DAMAGE THE GLASS.

• STEP 10: Once the rivets have been removed manually, slide the window glass into the closed position. Hold the glass in place with either a saddle cup assembly, painter’s tape, or a wedge.
  NOTE: If you are using a wedge, use care around the door glass weather stripping.

• STEP 11: Disconnect the window lift motor connector.

• STEP 12: Remove the window regulator attaching hardware.

• STEP 13: Remove the window regulator assembly through the main access hole.

• STEP 14: To remove the window lift motor, you must first remove the window regulator pre-tensioner spring. Place the window regulator in a vice. Once the window regulator is in a vice, use a pair of slip joint pliers to pull the bottom leg of the pre-tensioner off of the pre-tensioner mounting post.
  CAUTION: THE PRE-TENSIONER SPRING IS UNDER EXTREME PRESSURE. FAILURE TO REMOVE THE PRE-TENSIONER SPRING PROPERLY COULD RESULT IN PHYSICAL INJURY.
