How to Replace a Power Window Regulator How to Replace a Power Window Regulator

When power windows first showed up on automobiles, it was a luxury that changed the way we felt about driving around town. But, when you press the button for the window to roll down and nothing happens, you curse the day that luxury was ever conceived. What was ever wrong with having to wind the window down by hand anyway?

Driving around with an immovable window can go a long way toward turning a once pleasant driving experience into an anxiety-ridden and inconvenient headache, especially whenever you stop for gas, order through the take out window, pay a toll, and so on and so on. Here’s how you can fix your own power windows and save yourself a bundle.

  1. On the door with the immovable window, remove the door panel. This will require you to do some sleuth work to find all of the screws that are holding it in place, but once you do, the panel should come off easily.
  2. Carefully peel back the moisture barrier that is stuck to the inside of the door.
  3. Look for the regulator on the door. It is normally held in place by two bolts. Depending on the make of your car, you may have to manually lower the window to have access to these bolts.
  4. Disconnect the wiring on the regulator. Pay attention to how the wires or harness are attached to the unit.
  5. Remove the bolts and take out the old regulator.
  6. Install the new power window regulator using the two bolts you removed earlier.
  7. Connect the wires/harness to the new regulator.
  8. Reinstall the moisture barrier.
  9. Make sure all of the wires are back in place and secure the panel back to the door frame.
  10. Turn the key in the ignition and test your power windows.

If you follow these steps and the power window still does not operate properly, you may want to then take it to a professional for troubleshooting.
