How To Fix A Power Window Not Working?

Posted by Mariios on February 29, 2024

Do you ever find yourself pressing the button to roll down your car window, only to be met with silence? It can be frustrating when your power window stops working all of a sudden. To get your power window working again, start by checking the fuse box to see if a blown fuse is the issue. Next, inspect the window switch for dirt or corrosion that could hinder its function; if needed, clean or replace the switch. Test the window motor by listening for any noise when activating the switch and gently tapping on it to detect potential jams. 

Additionally, examine the window regulator for damage, and inspect the wiring for any signs of wear or damage. If necessary, try resetting the system by disconnecting and reconnecting the car battery. If all else fails, it’s advisable to consult a professional service provider like Blue Diamond Auto Glass for further diagnosis and repair. In this blog, we’ll explore some simple and effective steps on how to fix power window not working issues yourself before heading to an expert.

Steps To Fix Power Window Not Working Issue

Check The Fuse

The first thing you should do when it comes to how to fix a power window not working, is to check the fuse box. A blown fuse could be the culprit behind your malfunctioning power window. Consult your car’s manual to locate the fuse box and find the fuse that corresponds to the power windows. 

Inspect The Window Switch

Sometimes, the issue lies with the window switch itself. Dirt, grime, or corrosion can prevent the switch from making proper contact. Use a can of compressed air to clean around the switch and try operating the window again. If that doesn’t work, you may need to replace the switch.

Test The Window Motor

The power window motor is responsible for moving the window up and down. If the motor fails, your window won’t budge. To test the motor, listen for any noise when you press the window switch. If you hear a humming sound, it means the motor is getting power but might be jammed. Try gently tapping on the motor with a small hammer while simultaneously pressing the switch. If the window starts moving, the motor might be on its way out and needs replacement.

Consult A Professional

If you want to avoid getting it repaired yourself due to the busy schedule it is advised to seek help from a professional car window solution provider like Blue Diamond Auto Glass. They have the expertise and tools to diagnose and repair complex issues with power windows.

Inspect The Window Regulator

The window regulator is what holds the window glass in place and helps move it up and down. Sometimes, the regulator can become bent or damaged, preventing the window from functioning correctly. Carefully remove the door panel to access the regulator. Inspect it for any signs of damage or wear and tear. If you notice any issues, you’ll likely need to replace the regulator.

Check The Wiring

Sometimes, if the wires that connect the window motor and switch are broken or damaged, your power window might not work. Look closely at these wires to check if they’re okay. If you see any parts that are frayed or broken, you’ll have to fix or change them.

Try A Reset

In some cases, a simple reset can fix the problem. Disconnect the car battery for a few minutes, then reconnect it. This can reset the power to the window system and may resolve the issue.

What to do if the power window is not working? 

If your power window isn’t working, first, check the fuse box to see if the fuse related to the power windows is blown. If it is, you can replace it. If the fuse is fine, it might be a problem with the window switch or the window motor. You can try tapping on the window motor while pressing the switch to see if it starts working. If not, you might need to have it checked by a professional.

Can I fix the power window myself? 

Yes, you might be able to fix a power window issue yourself depending on the problem. Simple issues like a blown fuse or a stuck window can often be resolved with basic tools and some patience. If you’re not comfortable or experienced with car repairs, it’s best to seek assistance from a professional mechanic to avoid causing further damage. 

How do you fix a power window that won’t roll up? 

If your power window won’t roll up, there are a few things you can try. First, check the window switch to make sure it’s functioning properly. If the switch seems fine, try tapping on the window motor while pressing the switch to see if it starts working. If the window still won’t roll up, it might be a problem with the window regulator or the motor itself, which may require replacement. In such cases, it’s best to consult a professional mechanic for assistance. 

Why would only one power window not work? 

The most common causes include a faulty window switch, a malfunctioning window motor, a broken window regulator, or a wiring issue specific to that window. If you’re unable to identify the problem, it’s advisable to seek professional help for diagnosis and repair.


As we wrap up, by following key steps on how to fix the power window not working issue, you can hopefully get your power window up and running again without spending a hefty amount on repair services from car window experts. Remember to always prioritize safety and consult your car’s manual for specific instructions. Lastly, if you’re looking for a professional power window repair service provider, choose none other than Blue Diamond Auto Glass.
