How to Troubleshoot a Power Window Motor

Window motors are found on every car with power windows. The window motor is located inside the door panel. It moves the window up and down. After years of use, the window motor cam become damaged and worn down. If your window is moving extremely slow or is getting stuck, then there could be a problem with the window motor. The first step toward fixing the window motor is to find out what the exact problem is with the window.

Things You'll Need

  • Flat head screwdriver
  • Phillips head screwdriver
  • Pry bar
  • Super glue
  • Slide a flat head screwdriver into the cover over the top of the window switch. Move the screwdriver underneath and pull up to remove the cover. Loosen all of the screws holding the door panel in place with a Phillips head screwdriver and set them aside.

  • Slide a pry bar between the door and the door panel. Run it along the inside of the door panel and snap off all of the clips holding the panel in place. Pull up on the door panel and remove it from the door.

  • Peel off the plastic weather shield covering the entire inside of the door and locate the motor near the bottom of the door. Find out if there is an electrical problem. Follow along the wires on the motor to see if everything is connected. Check for damaged wires. Inspect the fasteners to make sure they are all tight.

  • Look over the window gasket to make sure it is sealed properly. The gasket is the rubber strip that is around the frame of the window. Run a flat head screwdriver through the gasket and clean out anything that may be in the way of the window. Make sure the gasket is not loose or torn and add super glue to repair the tears.

  • Check under the fuse box for a blown fuse. Pry open the box located under the dashboard with a flat head screwdriver and check the fuses in the box. Look for blown fuses that could be causing the motor not to run properly.
