What to Do If Power Windows Suddenly Stop Working?

Power windows are a convenient feature in modern vehicles that provide ease and comfort to passengers. However, sometimes they can stop working, leaving you frustrated and inconvenienced. Don’t worry, though!

If your power windows have stopped working, the first step is to check the fuse box and replace any blown fuses. Power windows may stop working due to a blown fuse, so this is the easiest and most common issue to fix.

Troubleshooting Power Windows

We will guide you through some troubleshooting steps to help you find the issue and get your power windows up and running again.

Check the Fuse

One of the first things you should check when your power windows stop working is the fuse. A blown fuse can cut off power supply to the windows, causing them to malfunction. Follow these steps to check the fuse:

  1. Turn off the ignition and locate the fuse box in your vehicle.
  2. Open the fuse box cover and find the diagram to identify the power windows fuse.
  3. Use a fuse puller tool or a pair of needle-nose pliers to carefully remove the fuse.
  4. Inspect the fuse for any signs of damage, such as a broken filament or discoloration. If the fuse is blown, replace it with a new one of the same amperage rating.
  5. Once the new fuse is in place, close the fuse box cover and test the power windows to see if they are working again.

Inspect the Switches and Buttons

If the fuse is not the culprit, the next step is to inspect the switches and buttons that control the power windows. Sometimes, these components can get dirty or worn out, leading to malfunctioning windows. Follow these steps to inspect the switches and buttons:

  1. Start by cleaning the switches and buttons with a specialized electrical contact cleaner. This can remove any dirt or debris that may be interfering with the electrical connections.
  2. After cleaning, check for any visible damage, such as loose connections or broken parts. If you notice any issues, you may need to replace the faulty switch or button.
  3. Test the power windows after cleaning and inspecting the switches to see if they are functioning properly.

Test the Window Motor

If the fuse and switches are in good condition and the power windows are still not working, it’s time to test the window motor. The motor is responsible for the actual movement of the windows, so if it’s faulty, the windows won’t function properly. Follow these steps to test the window motor:

  1. Locate the window motor, which is usually found inside the door panel. Refer to your vehicle’s manual for specific instructions.
  2. Disconnect the electrical connector that connects the motor to the window switch.
  3. Use a multimeter set to the ohm setting to check the resistance of the motor. If the reading is significantly different from the manufacturer’s specifications, the motor may need to be replaced.
  4. If the motor passes the resistance test, you can also try applying direct power to it using jumper wires. This can help determine if the motor is receiving power and functioning correctly.
  5. If the motor fails any of these tests, it’s likely that it needs to be replaced. Consult a professional mechanic for further assistance.

Preventing Power Window Issues

If your power windows suddenly stop working, it can be frustrating and inconvenient. To avoid this problem and ensure the smooth functioning of your power windows, it’s important to take preventive measures. Here are a few maintenance tips to follow:

  1. Clean the window tracks and mechanisms regularly to remove any built-up dirt or debris that could hinder their movement.
  2. Apply silicone spray or a suitable lubricant to the rubber seals and moving parts to keep them well-lubricated and prevent friction.
  3. Inspect the wiring and connections periodically to ensure there are no loose or damaged wires.
  4. If you notice any signs of wear or damage, such as frayed cables or broken switches, have them repaired or replaced promptly to prevent further issues.

One common reason for power window failure is exerting excessive force while operating them. To prevent this, keep the following points in mind:

  • Do not slam the doors: Avoid slamming the doors, as it can put unnecessary strain on the power window system.
  • Operate the windows gently: Use a smooth and gentle motion when opening or closing the windows, and avoid jerking or yanking them forcefully.
  • Prevent obstructions: Be cautious of any objects, such as ice or debris, that may obstruct the window’s movement. Clear any obstructions before operating the windows.
  • Do not use the power window switches excessively: While it may be tempting to continuously use the power window switches, especially during hot weather, it’s important to give them time to rest and prevent overheating.

Water damage is another common cause of power window issues. To protect your power windows from water-related problems, follow these steps:

  1. Avoid direct exposure to heavy rain or car washes: Whenever possible, park your vehicle in covered areas or use a car cover to shield it from heavy rain and prevent water from seeping into the power window mechanisms.
  2. Keep windows closed during rain: While it may seem obvious, it’s important to ensure your windows are fully closed during rainy weather to prevent water from entering the cabin and reaching the power window components.
  3. Address leaks promptly: If you notice any water leaks around your windows, have them repaired quickly to prevent water from damaging the power window system.


If your power windows have suddenly stopped working, don’t panic. It’s crucial to diagnose the issue correctly before attempting any repairs. Start by checking the window switches, fuses, and wiring connections. If these steps don’t solve the problem, it might be time to seek professional assistance.

Recall that solving your power window issues will be easier if you maintain your composure and practice methodical thinking.
