What is a Window Regulator and where is it Located?

Window regulators are key components in the proper operation of your vehicle’s windows. Since we use our windows so often, they are also some of the most actively used parts in any vehicle. Window regulators help to raise and lower the door glass of an automotive, and are located behind the door panels. Depending on the type of windows a vehicle is equipped with, it will either have manual or power window regulators.

If a vehicle has manual windows, then it will have manual window regulators. This type of regulator lifts the door glass up and down when someone physically rotates the window crank handle located on the door, which is connected to the regulator assembly. If a vehicle is equipped with power windows, which are what most come with nowadays, then it will have power window regulators. In this case, electricity is the power behind the opening and closing of the vehicle’s door window glass. A power window regulator assembly has a window motor attached to it which is controlled by a power window switch, which is usually located on the door panel or the vehicle's console. When someone pushes the switch, the window motor is activated and the motor then powers the linkage of the window regulator, moving the windows up or down.

For an in-depth explanation of the different kinds and styles of window regulators that there are, maintenance tips, and more, check out our replacement window regulator guide.

5. What caused my old window regulator to fail?

Your window regulator may need to be replaced for many reasons. The more common causes of window regulator failure are excessive strain and breakage caused by forcing the window, old or worn pulley and cable lines, and general wear and tear. For these reasons, it is important to choose a quality designed and manufactured window regulator.

Problems that may contribute to broken regulators:

  • - Damaged window track
  • - Worn or compromised weatherstripping
  • - Misaligned window
  • - Misplaced window stops
  • - Obstructions in the windows or doors
  • - Weakened balance springs
  • - Ground wiring fault

6. Tips on how to replace a window regulator:

  • - Obtain a copy of the dealer service manual procedure. Many dealer customer service or parts
      counters will let you copy this information if you ask nicely. Some may charge for it, but either way,
      having the correct procedure and diagrams is invaluable.
  • - Understand how your window aligns. Windows have many adjustment points that control how far up,
      how far down, angle when the window is down, angle when the window is up, forward and rearward
      pitch of the window. Making sure your window is aligned properly and goes up and down without
      obstruction (when attached to the mechanism) is crucial in extending the life of your new window
      motor.
  • - Choose an appropriate work area and have patience.
  • - Make sure you have a large protected space to work in.
  • - Allow yourself plenty of time and don't hurry. A window lift motor installation can be a day long
      project.
  • - Don't start the project on a night where you need the car the following morning.
  • - Don't let yourself be rushed by the weather.
  • - Before you reassemble the door, do many slow tests of the window motor. Move it up and
      down, looking for potential problems with the newly installed window motor.
