Car electrical repair near me: If you have electric (power) windows in your car, there may come a time that you push the button and the window doesn’t respond the way it used to. If the window suddenly stops moving at all, the problem could be as simple as a blown fuse or a loose connection. It is also possible that you have a faulty switch, especially if the window works on a hit and miss basis. Window motors go down sometimes as well. This is usually characterized by a gradual decrease in how well the window responds to the switch, but a slow window could also be getting stuck on the gaskets. Once you identify the problem, you may be able to repair it with some basic tools.

1. Locate and open the fuse box.
It should be located inside the car as a part of, or near, the dash.
2. Check your owner’s manual to locate that operates the windows.
It is not uncommon that the only thing wrong with electrical components in a vehicle is a blown fuse. If this is the case with your windows you will need to replace the window fuse.
3. Pull the fuse straight out of its cradle.
Be careful not to twist or otherwise force it. You do not want to damage the cradle or break a piece of the fuse off in the cradle. There are fuse tongs available at part supply stores that can help with this.
4. Locate a replacement fuse.
It must be the rated for the same amperage as the original fuse that operated the window mechanism. The amp rating should be printed on the fuse, and it should also be listed in your owner’s manual. Do not use a fuse with a higher amp rating, as this may lead damaging the electrical components of your vehicle.
5. Push the new fuse straight down into the cradle.
The fuse must be “set”. This means that it does not move or wobble.
6. Turn your car key to the “on” position.
This provides power to your windows and allows you to test them. You need not start your car.
7. Test your windows.
Confirm that they go up and down without restriction.
Repairing Window Gaskets
8. Evaluate the condition of your window seals and gaskets.
9. Check the entire gasket channel for foreign objects.
10. Clean the gasket with acetone.
- Be very careful not to get any acetone on your car’s paint or carpets. It’s better to put a small amount on a cloth and wipe with the cloth than to pour the acetone directly on the gasket.
11. Repair any small tears.
You can do this using a rubber adhesive or glue. Be sure to trim any loose corners with a razor blade so that you get a good seal.
12. Replace the gasket.
This may be necessary if the original gasket has large tears or several small tears. Replacing the gasket is a fairly easy job.
- Use a trim removal tool to slide in between the window and the gasket.
- Hook the tool underneath the gasket and pull up.
- Once the old gasket is removed, install the new gasket by fitting it into the same place as the original and pushing down firmly.
13. Lubricate the channel with silicone spray.
This will help your window glide smoothly along the channel.
14. Retest the window.
Your window should move up and down without restriction or delay if the problem has been fixed.
15. Find an electrical schematic of your vehicle.
This can be found either from information in your owner’s manual or on the Internet.
16. Trace the wiring from the fuse panel to the switch.
17. Use a multi-meter to confirm that the switch is getting 12V of power.
18. Trace the wiring from the switch to the motor.
19. Use the multi-meter to confirm that the motor is getting 12V of power.
20. Look for any interrupted voltage caused by a loose connector or corrosion.
21. Fix the connector or corroded areas.
22. Test the window again.
Replacing a Faulty Switch
23. Locate the window switch panel.
This is the button used to operate your window. It is almost always on the door, however, they are rarely found on the center console.
24. Remove the window switch panel.
Be careful not to scratch up the door panel while removing the window switch, as it often requires prying. Using a shop rag or piece of cardboard under your prying tool can help.
25. Unplug the wiring connectors from the switch.
26. Use your multi-meter to probe each connector.
27. Check the wiring on any switch that has a low voltage reading.
28. Test another switch.
29. Buy a new switch.
30. Install the new window switch.
Replacing Your Window Motor or Regulator
31. Remove the door panel.
32. Use a multi-meter to make sure that the motor is getting the correct voltage.
33. Ensure that the window moves freely during this test.
34. Unplug the motor.
- If your motor is functioning properly but the window is not responding, you may need to replace your regulator.
35. Remove the bolts that attach the regulator to the glass.
The regulator is the lift assembly that moves your window up and down. You will have to move the window up or down to align these bolts with a hole in the door interior. Using an extension on a ratchet, you will put a socket (usually 8 or 10 mm) through the hole and loosen the two bolts.
36. Push the window all the way up.
Use your hands to push the window up, and then either fasten it with tape or pull it out of the door altogether.
37. Unplug the wiring harness from the window motor.
You will have to press down on the clip that holds the wiring harness into place and pull the harness out. These can be hard to press and sometimes it is best if you can get a screwdriver on it to press it in.
38. Unbolt the harness and/or motor from the door’s interior.
- These can often be difficult to bolts to remove. You may need to use a ratchet with a long extension to provide the necessary angle to access and turn the bolts.
39. Pull the motor and harness out as one assembly.
40. Re-install the motor/regulator assembly.
41. Plug up the new motor.
42. Lower your window back into its correct place on the wiring harness.
43. Bolt the window to the regulator.
44. Test your window.
45. Things You’ll Need
- Contact cement
- Silicone spray
- Lacquer thinner
- Razor blade or utility knife
- Screw drivers and socket wrenches
- Assorted fuses of different voltages
- Fuse puller
- Paper towels and shop rags
- New rubber gasket (if needed)
- New toggle switch (if needed)
- New window motor (if needed)
46. More tips
If your window is stuck in the down position and you do not have time to repair it, you can push it up with or try to turn the motor manually to roll it up. This may require taking your interior door panel off, but once the window is up you can tape it in that position.
If you must replace the window motor, proceed with extreme caution. The window motor has a lot of torque and can remove a finger if it is activated and your fingers are in the gears. To safely remove a window motor, the linkage arms should be secured in a vice before the springs and motor are removed.
