Why are my power windows not working in my car?

If your car's power windows are not functioning, there could be several potential causes. The most common issues include a blown fuse, a faulty window motor, or a problem with the window switch. Let's explore these potential problems in more detail.


Blown Fuse


One of the first things to check is the fuse for the power windows. The fuse may have blown, preventing the electrical current from reaching the window motors. Locate the fuse box, usually found under the dashboard or in the engine compartment, and inspect the fuse for the power windows. If it is blown, replace it with a new fuse of the same amperage rating. If the new fuse also blows, there may be a more serious electrical issue that needs to be addressed.


Faulty Window Motor


Another common cause of non-functioning power windows is a faulty window motor. Over time, the motor can wear out or become damaged, preventing the window from moving up and down. To diagnose a faulty motor, you can try manually operating the window. If the window does not move at all, even with manual force, the motor is likely the culprit. In this case, the window motor will need to be replaced.


Problematic Window Switch


The window switch, located on the door panel, is responsible for sending the electrical signal to the window motor. If the switch is malfunctioning, it may not be able to properly control the window's movement. You can test the switch by using a multimeter to check for continuity when the switch is pressed. If the switch is not functioning correctly, it will need to be replaced.


Other Potential Causes



  • Wiring issues: Damaged or loose wiring can prevent the electrical signal from reaching the window motor.

  • Window regulator problems: The window regulator, which is the mechanism that physically moves the window, can become worn or broken, preventing the window from operating.

  • Computer/module failure: In some modern vehicles, the power windows are controlled by an electronic control module or computer. If this component fails, the windows may not work.


If you have checked the fuse, motor, and switch, and the problem persists, it's best to have a professional mechanic diagnose and repair the issue to ensure your power windows are functioning correctly and safely.

Why did my windows suddenly stop working?


Regular use or aggressive touch can wear the power switch out to a point that it stops working properly. A malfunctioning power switch is the most common reason why a power window is not moving. Power switch replacement is inexpensive.



How do I reset my electric windows in my car?


Down. And hold the button down for five seconds. And then pull it all the way up. And once it's all the way up hold the button for five seconds and that reprograms. It hope that helps.



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.



What is the most common issue with power windows?


One of the most common reasons for power window failure is a faulty window regulator. The window regulator is responsible for controlling the up-and-down movement of the window glass. Over time, the regulator's internal components can wear out, leading to issues such as the window getting stuck or not moving at all.



Is there a fuse for each power window?


Generally most systems have only 1 fuse for the entire power windows so with only 1 window not working, I do not suspect a fuse and instead a faulty window motor or window switch.



What would cause all power windows to stop working?


If all windows stopped working at once, a loss of power to the system is likely. Many systems use a single relay and power supply for all windows. When all windows quit working simultaneously, first check for a blown fuse or bad relay.



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 have my electric windows stopped working?


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.



How much does it cost to fix a car window fuse?


Expect to pay as little as $20 if you're just replacing a blown fuse. Swapping out a window switch will usually run $150-$250. Replacing a window motor will likely cost $300-$400.



How do you fix an electric car window that won't go up?


First, find the switch for the malfunctioning window. Then, press and hold the switch in the 'up' position for about ten seconds. After releasing it, immediately press and hold the switch in the 'down' position for another ten seconds. This recalibrates the window motor and resets its position memory.
