1. Two Effective Ways to Roll Up a Power Window That Stopped Working

Depending on the failure, you might be able to roll up a stuck power window. If the switch works but the motor is faulty, jarring the motor while holding the switch up can sometimes work.

Here’s how to roll up a stuck electric window without tools:

1. Turn the ignition to the “on” or “accessory” position. Ensure other windows and the radio function.
2. Press and hold the window switch in the “closed” or “up” position. Hold the button firmly, ensuring you’re pushing the correct side to close the window.
3. While holding the switch, open and slam the car door. Repeat a few times if necessary. If successful, the window should roll up while you hold the button. If this doesn’t work, try the next step.
4. Close the door and find a spot on the door panel that seems to contact the metal inside. Finding the precise location might require referring to online images of your car with the door panel removed.
5. While holding the switch, strike that spot with your fist or a blunt object. Be cautious not to injure your hand or harm the door.
6. If the window rolls up, leave it until you can properly fix the problem. If it doesn’t, check the fuse, switch, or motor, or consult a professional.

2. Window Track Issues: Getting Your Car Window Back on Track

If you hear grinding when trying to roll up the window, or if the motor runs without moving the window, the regulator might be faulty, or the window could be off track.

If the window isn’t fully down, follow these steps:

1. Turn the ignition key to the accessory position.
2. Open the door and sandwich the window between your palms.
3. Ask someone to push the window switch.
4. Apply pressure and try lifting the window. Use caution to prevent hand injuries if the window suddenly moves.

If the window is down and you hear grinding or see the glass rocking, you’ll need to remove the door panel to lift the window while pushing the switch.

3. Common Causes of Electric Window Failures: Identifying the Culprits

Electric windows typically fail due to blown fuses, faulty switches, or burned-out motors. The window regulator can also wear out, bend, or get stuck, although this is less common. Addressing these issues can range from simple fixes to more complex repairs requiring professional help.

Here are essential troubleshooting tips for electric windows that won’t operate:

1. Check the window safety lock-out switch. Ensure it’s not engaged, as it prevents window operation.
2. Inspect the fuses. If none of the windows work, check the fuses and replace any that are blown. If a fuse blows again, investigate for a short circuit, and never use a higher-rated fuse than recommended.
3. Listen to the switch. If you hear a sound inside the door when you press the switch, the switch is likely working, and the motor or regulator might be the issue.
4. Watch the dash gauges. If the volt gauge dips when you push the switch, suspect a bad motor.
5. Test other switches. If one window doesn’t work, try the main switch on the driver’s side. If it works, the individual switch is faulty.
6. Swap switches. If the switches are identical, swap one from a working window to a non-working one to identify a bad switch.
7. Check switch power. If the switch has power and ground, suspect the wiring or motor.
8. Check motor power. If the motor receives power and ground but doesn’t work, it’s likely bad.

4. The Lockout Switch: A Simple Solution to Stuck Windows

Power window motors and switches fail over time, but start with the simplest issue: the lockout switch.

Most vehicles with power windows have a safety lockout switch, usually on the main switch panel on the driver’s door or center console. This switch prevents accidental window operation, especially by children or animals.

:max_bytes(150000):strip_icc()/carwindowsstucklockswitch-5b552491c9e77c005bb950ce.jpg)

If your windows stop working, check this switch first. It’s easily bumped accidentally. The switch icon varies but usually resembles a crossed-out window. After toggling the switch, test the windows again.

5. Blown Fuses: Identifying and Resolving Fuse-Related Issues

In most cars, all window motors are on the same circuit, powered by a single fuse. If all windows stop working simultaneously, a blown fuse is a likely cause. Replacing it might restore window operation.

Fuse boxes are typically under the dash, in the glove compartment, or in the engine compartment. Some vehicles have multiple fuse boxes. If you can’t find the fuse box in your owner’s manual, search online or contact your local dealer.

Visually inspect the power window fuse by removing it from the fuse box. Most automotive fuses are semi-transparent, allowing you to see if the fuse is blown.

If visual inspection isn’t conclusive, use a test light or voltmeter to check for power on both sides of the fuse. If you’re uncomfortable with this, consult a professional.

Replace a blown fuse with a new one of the same amperage rating. If the new fuse blows again, there’s likely a short circuit or a motor problem causing excessive amperage draw.

Never replace a blown fuse with a higher-rated fuse, as it can cause a fire.

6. Window Motor Malfunctions: Recognizing the Signs of Motor Failure

Diagnosing a car window that won’t roll up requires specialized equipment, so start with simpler checks.

Some cars have a voltage meter on the dash, indicating the charging system’s health. With the car off, it typically reads 12-13 volts, increasing when running.

:max_bytes(150000):strip_icc()/carwindowsdontworkvoltgauge-5b55faeac9e77c0037bc999a.jpg)

Use the voltmeter to check the window motor switch:

1. Turn the key to the accessory position.
2. Push the window switch.
3. Watch for any movement on the voltage meter.

Even a slight dip indicates the motor is trying to work, suggesting the switch is fine, but the motor might be bad or the regulator is stuck. A visual inspection after removing the door panel can confirm this.

7. Ruling Out Bad Window Switches: Diagnosing Switch-Related Problems

If your vehicle uses identical power window switches, you can test a suspect switch by swapping it with one from a working window.

Temporarily replace the switch on the non-working window with a known good switch. If the window now works, the original switch is faulty and needs replacement. If the window still doesn’t work, the issue might be wiring or the window motor.

8. Checking for Power at the Car Window Switch: Electrical Diagnostics

Further diagnostics require specialized tools and knowledge. If you’re not comfortable working on your car, consult a professional.

If you have a voltmeter, check for power and ground at the power window switch. Most switches have a power terminal, two ground terminals, and two terminals connected to the motor.

With the switch in neutral, one terminal should have power, two should show ground, and the remaining two should have neither. Pushing the switch one way should power one of the latter terminals and ground the other, reversing when pushed the other way.

Different results indicate a bad switch, unless the switch itself lacks power or ground, which indicates a wiring problem. Check the wires passing into the door for crimps or breaks.

9. Checking for Power at the Car Window Motor: Motor Voltage Tests

If the switch tests fine, check for power at the motor by removing the door panel. You might find a protective plastic sheet and a second interior panel behind the door.

Use your voltmeter to check for power at the motor with the ignition in the accessory position and the window switch activated. Voltage at the motor without operation means the motor is bad.

10. Understanding How Car Windows Work: Mechanisms and Functionality

Car windows use a regulator to raise and lower them inside channels. Manual windows have regulators connected to cranks, while electric windows have regulators connected to motors.

Electric windows can fail due to issues with switches, wiring, or the motor, while manual windows can have stripped gears or a bent regulator. Regular maintenance, including lubrication, can extend their lifespan.

• Electric windows: They use a reversible electric motor connected to a regulator. The switches, wiring, and motor can fail, and the regulator can also get stuck.
