Why did my power window suddenly stop working?
If your power window has suddenly stopped working, there could be a few potential reasons behind the issue. Power windows are a convenient feature in many modern vehicles, but they can sometimes experience problems that require troubleshooting and repair. In this article, we'll explore the common causes of power window failure and provide steps you can take to diagnose and potentially fix the problem.
Common Causes of Power Window Failure
There are several reasons why a power window might suddenly stop working. Some of the most common causes include:
- Blown fuse: A blown fuse in the vehicle's electrical system can prevent the power window from functioning. This is often an easy fix, as you can simply replace the fuse.
- Faulty power window motor: The power window motor is responsible for raising and lowering the window. If the motor fails, the window will no longer move.
- Broken window regulator: The window regulator is the mechanism that physically moves the window up and down. If the regulator becomes damaged or worn out, the window may not operate properly.
- Wiring issues: Problems with the wiring that connects the power window switch to the motor can also cause the window to stop working.
- Stuck window: In some cases, the window may become physically stuck in the door frame, preventing it from moving up or down.
Determining the exact cause of the power window failure will help you decide the best course of action to get it working again.
Troubleshooting Steps
If your power window has stopped working, here are some steps you can take to diagnose and potentially fix the issue:
- Check the fuse: Locate the fuse box in your vehicle and check the fuse for the power window circuit. If the fuse is blown, replace it with a new one of the same amperage rating.
- Test the power window switch: Use a multimeter to check if the power window switch is receiving power and sending the correct signals to the window motor. If the switch is faulty, it may need to be replaced.
- Inspect the window regulator: Visually inspect the window regulator for any signs of damage or wear. If the regulator is broken, it will need to be replaced.
- Check the window motor: Use a multimeter to test the power window motor. If the motor is not receiving power or is not functioning properly, it will need to be replaced.
- Inspect the wiring: Carefully examine the wiring that connects the power window switch to the motor. Look for any signs of damage, such as frayed or loose connections, and repair or replace the wiring as needed.
- Manually move the window: If the window is physically stuck, try to manually move it up and down. This can sometimes help free a stuck window and restore normal operation.
If you've tried these troubleshooting steps and the power window still isn't working, it's likely that the issue is more complex and may require the expertise of a professional mechanic to diagnose and repair.
How do I know if my power window fuse is blown?
If the fuse is blown, pushing a window button will do nothing at all: The motor won't groan and the glass won't quiver. If the fuse is good and you can hear the motor, or the glass acts like it wants to move, then you've got some sort of mechanical problem.
Why did my electric window suddenly stop working?
Blown Fuse or Circuit Issue
Electric windows rely on your vehicle's electrical system, which means a blown fuse or a problem in the wiring can stop them from working entirely. This should be one of the first things you check if your window suddenly stops functioning as it should.
Where is the fuse for the power windows located?
This is usually located within the dash of the car by the steering wheel, and there is another under the hood of the car. Once you locate the fuse box that corresponds to the power windows, if the fuse is blown, replace it with the same type of fuse.

What would cause a car window to stop working?
If your car is equipped with electric windows (as most vehicles today are), the malfunction is likely caused by faulty switches, wiring, or a motor gone awry.
How to tell if it's the window motor or switch?
How do you know if it's the window regulator or the motor? If the window glass is going up crooked, sags into the door when it's not being used, or it has fallen, it's a window regulator issue. If it's an issue of movement, then the window motor is the usual suspect.
Does each power window have its own fuse?
With some arrangements a single fuse in the main supply line is used to protect the complete window system so a failure here affects all the windows. Other cars have individual fuses for each window motor so failure will only affect the one window.
How to fix an electric window that won't go up?
If your window won't roll up, check the fuse, try other window switches, and inspect for obstructions before seeking professional help. Can you manually raise a power window? You can manually raise a power window by carefully holding the glass and applying upward pressure while someone operates the window switch.
Why would only one power window not work?
If only one window stops working, the problem could be a bad relay, fuse issue, bad motor, or the power window switch has failed. The most common reason for one window to stop working is the switch, so this should be looked at by a professional mechanic to have your power window switch replaced.
How much does it cost to fix a car window that wont work?
Side Window Repair: Repair or replacement costs typically range from $100 to $400. Power windows or specialized glass can increase the expense. Rear Window Repair: Depending on the damage type and features like defrosters, these costs can range from $200 to $600.
