Topics: How To Fix Electric Car Window?

If your car’s power windows are stuck or closed, this is a significant inconvenience. If they’re stuck open, you won’t be able to close them in the event of rain or safe valuables. If they’re stuck, you can’t open them when you need to let in fresh air or hand over money one toll at a time.

If this happens, the root of the problem could be mechanical or electrical. This guide from Vermin-Club will help you locate and solve the problem so that your windows can function correctly.

Step 1: Mechanical Diagnosis

If you flip the window switch and hear or see the window try to move, it is more likely a mechanical problem than an electrical problem. To solve a mechanical issue, you will need:

  • Butyl rubber tape
  • Door panel screws (typically 8mm, 10mm, T30, or Phillips)
  • Window cleaner
  • Gloves
  • Digital multimeter
  • Panel popper tool
  • Safety glasses
  • Silicone spray
  • Cutting block
  • White lithium grease

Once you have gathered these materials, you are ready to troubleshoot the mechanical problem.

Step 2: Mechanical Repair

Follow these steps to repair a mechanical problem with your car windows:

  • Remove the door panel. Locate retaining screws, usually behind covers or gaskets, and unscrew. The process of removing the door panel varies depending on your particular car.
  • Remove the vapor barrier, which is usually held in place with butyl tape.
  • Visually inspect the cables or window guides for broken or misaligned parts. If you see a loose or broken wire and hear the motor move when you press the window switch, you may need to replace the window regulator.
  • If the cables are intact and the guides aligned, the window motor may have bare gears. Remove the governor motor to check.
  • Replace or repair any broken or stuck parts.
  • Lubricate moving parts and window guides, and clean glass.
  • Reinstall the door panel by following the reverse process of how you removed it.

Step 3: Electrical Diagnosis

If you flip the window switch and if nothing moves or if you don’t hear any noise coming from inside the door, it’s probably an electrical problem. Diagnosing an electrical problem requires the same materials that are listed to solve a mechanical problem. Once you’ve gathered them, you’re ready to move on to diagnosis.

Step 4: Electrical Repair

Follow these steps to repair an electrical problem with your car windows:

  • Locate and check the faulty window motor fuse. If it has blown, replace the fuse. A blown fuse can indicate increased power consumption due to a stuck or worn mechanical component, so you should continue with the automatic repair process after replacing the fuse.
  • Remove the door panel. Locate retaining screws, usually behind covers or gaskets, and unscrew. The process of removing the door panel varies depending on your particular car.
  • Check the electrical entry on the power and ground wires, usually the two largest wires connected to the window motor. Connect the multimeter to the leads, then turn on the window switch with the car key in the on position. If you are receiving power both ways from the switch, the motor’s electrical wiring is in good condition, and the motor needs to be replaced. If you are not providing power to the motor wiring, you need to check if the window switch has power.

If the power goes to the window switch but does not go out, replace the window switch. Failure to turn on the window switch could indicate a major electrical problem that a qualified mechanic should inspect.

Once you’ve located the source of the problem, follow the same steps to clean, lubricate, and replace the parts that you previously scrapped.
