What causes a power window motor to stop working?
A power window motor can stop working for a variety of reasons, including electrical issues, mechanical problems, or a combination of both. In this article, we'll explore the common causes of a malfunctioning power window motor and provide guidance on how to troubleshoot and address the issue.
Electrical Issues
One of the most common reasons for a power window motor to stop working is an electrical problem. This can be caused by a variety of factors, such as a blown fuse, a faulty switch, or a problem with the wiring. To diagnose an electrical issue, you'll need to check the following:
- Fuse: Locate the fuse that powers the power window motor and check if it's blown. Replace the fuse if necessary.
- Switch: Test the power window switch to ensure it's functioning correctly. If the switch is faulty, it will need to be replaced.
- Wiring: Inspect the wiring between the switch, the fuse, and the power window motor for any signs of damage or loose connections. Repair or replace the wiring as needed.
If the electrical components are all in working order, the issue may be mechanical in nature.
Mechanical Issues
Mechanical problems can also cause a power window motor to stop working. This can be due to a variety of factors, such as a broken window regulator, a seized motor, or a problem with the window track. To diagnose a mechanical issue, you'll need to inspect the following:
- Window regulator: The window regulator is the mechanism that moves the window up and down. If the regulator is broken or worn, it can prevent the window from moving properly.
- Motor: The power window motor itself may be seized or malfunctioning, preventing the window from moving.
- Window track: The window track can become damaged or obstructed, preventing the window from moving smoothly.
If the mechanical components are the issue, you may need to replace the window regulator, the power window motor, or repair the window track to restore proper function.
Troubleshooting and Repair
To troubleshoot a malfunctioning power window motor, start by checking the electrical components first. If the electrical system is functioning correctly, then the issue is likely mechanical in nature. In either case, it's important to identify the root cause of the problem to ensure a successful repair.
If you're not comfortable performing the repairs yourself, it's best to take your vehicle to a qualified mechanic or auto repair shop. They will have the necessary tools and expertise to diagnose and fix the issue, ensuring your power windows are back in working order.
Is there a seperate fuse for each power window?
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 long should a power window motor last?
How long do window motors last? Most window motors last more than 10 years, but it's possible for one to fail much sooner.
How much does it cost to replace a power window motor?
The average time to replace a power window motor is 2.1 hours. You should expect to pay $120-$150 for labor plus the cost of the motor itself. It can usually bring the entire job anywhere from $200 to $300, depending on the make and model.
How do I reset my power window motor?
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 window motor have its own fuse?
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.
How to fix an electric 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.
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.
How do I know if my power window motor is bad?
If there are strange grinding noises, the motor moves slowly, or it doesn't move properly in one or both of the two directions, the window lift motor is the culprit.
What makes a window motor stop?
As a vehicle gets older, the window regulator and slides don't slide/move as well, so creates a lot more friction. The window motor starts wearing out because of this and more heat is produced, thus shutting down the motor.
Why did my power window suddenly stop working?
Power switch failure is a fairly common issue. The main control switch, located on the driver's side, can be found in many vehicles. This switch can operate all of the windows and also may have a locking safety mechanism to use for childproofing. Over time this switch can go bad and need to be replaced.
