1. Two Quick Fixes to Raise a Stuck Power Window

Depending on the nature of the failure, you might be able to raise a power window that’s stuck. If the switch is fine but the motor isn’t working, try these methods to potentially get the window up one last time.

1.1. Jarring the Motor Method

This method involves using physical jolts to try and trigger the motor.

1. Turn the ignition to the “On” or “Accessory” position. Confirm that other electrical components like the radio work, indicating you’re in the correct mode.
2. Press and hold the window switch in the “Up” or “Close” position. It’s essential to maintain continuous pressure on the switch, ensuring you’re pressing the side that closes the window.
3. While holding the switch, open and firmly slam the car door. Repeat this several times if it doesn’t work immediately. If successful, the window should begin to roll up as long as you keep the button pressed. Important: Avoid rolling the window back down until you can properly fix the underlying issue, as this temporary fix might not work again.
4. If the window remains stuck, close the door and identify a spot on the door panel that appears to contact the metal inside the door. Refer to online images of your car’s door with the panel removed if you’re unsure where to strike.
5. With the switch depressed, strike this location with your fist or a blunt object. Exercise caution to avoid injuring your hand or damaging the door.
6. If the window moves up, leave it until you’re ready to address the problem correctly. If not, further troubleshooting is needed to determine if the issue is a blown fuse, faulty switch, or bad motor. Alternatively, consult a professional.

1.2. Assisting the Window Manually

If you hear grinding sounds or the motor isn’t engaging, the window may be off track.

1. Turn the ignition key to the accessory position.
2. Open the door and place your palms on both sides of the window, sandwiching it between them.
3. Ask someone to activate the window switch.
4. Apply pressure to lift the window as the switch is engaged. You may need to grip the top of the window for better leverage.
5. Be cautious of sudden movement, and avoid getting your hands trapped as the window closes.

If the window is entirely 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.

2. Common Reasons Why Automatic Windows Fail

Several factors can cause electric windows to fail, including:

• Blown fuses
• Faulty switches
• Burned-out motors
• Worn, bent, or stuck window regulators

Some issues are easy to fix, while others need specialized tools or professional assistance.

2.1. Basic Troubleshooting Steps

Here are some basic troubleshooting steps to try when your electric windows fail:

1. Check the Window Lockout Switch:
   • The lockout switch prevents windows from operating.
   • Ensure it’s not accidentally activated.
   • The switch is often found on the driver’s door or center console.
2. Inspect the Fuses:
   • Check the fuses if none of the windows work.
   • Replace blown fuses with the correct amperage.
   • If the fuse blows again, there may be a short circuit.
   • Do not use a higher-rated fuse than recommended.
3. Listen to the Switch:
   • Listen for sounds inside the door when activating the switch.
   • A sound indicates the switch is working, suggesting a motor or regulator issue.
4. Monitor the Dash Gauges:
   • Watch the volt gauge while pressing the switch.
   • A slight movement suggests a functioning switch but potentially a bad motor.
5. Test Other Switches:
   • Try the main switch on the driver’s side for passenger windows.
   • If it works, the passenger-side switch may be defective.
6. Swap Switches (if possible):
   • If the switches are identical, swap one from a working window.
   • If the window then works, the original switch is bad.
7. Verify Power to the Switch:
   • Check for power and ground at the switch.
   • If power is present, the issue may be with the wiring or motor.
8. Check Power to the Motor:
   • If the motor receives power and ground, but doesn’t operate, the motor is likely faulty.

2.2. Detailed Checks: Lockout Switch

The lockout switch is a common culprit.

• It’s designed to prevent accidental window operation, particularly by children.
• The switch is usually a toggle located on the main switch panel.
• The icon resembles a crossed-out window.
• Ensure it’s not accidentally engaged.

2.3. Detailed Checks: Fuses

Fuses protect the electrical circuits.

• All window motors often share a single fuse.
• Check the fuse box location in your owner’s manual.
• Visually inspect the fuse for breaks.
• Use a test light or voltmeter to check for power on both sides.
• Replace blown fuses with the same amperage rating.
• Do not use a larger fuse, as it can cause a fire.

2.4. Detailed Checks: Window Motor Malfunction

A voltmeter on the dash can help diagnose a bad motor.

1. Turn the key to the accessory position.
2. Push the window switch.
3. Watch for any movement on the voltage meter.
4. Any movement suggests the motor is trying to work, indicating a faulty motor or regulator.

2.5. Detailed Checks: Window Switches

Swapping switches can isolate a faulty switch.

1. Remove a working switch from another window.
2. Replace the suspect switch.
3. If the window now works, the original switch is bad.

2.6. Testing for Power at the Switch

Use a voltmeter to check for power and ground at the switch.

• Most switches have a power terminal, two ground terminals, and two motor terminals.
• In the neutral position, one terminal should have power, two should have ground, and two should have neither.
• Activating the switch should reverse the power and ground on the motor terminals.
• If the results differ, the switch may be bad or there may be a wiring problem.
• Check the wiring, especially where it passes into the door, for crimps or breaks.

2.7. Testing for Power at the Motor

This requires removing the door panel.

1. Remove the door panel and any protective plastic sheeting.
2. Use a voltmeter to check for power at the motor while activating the switch.
3. If there’s voltage but the motor doesn’t work, the motor is bad.

3. Fixing Manual Windows: A Simpler Approach

Manual windows have fewer components and potential issues. The primary causes of failure are:

• Stripped gears in the crank
• Problems with the regulator

3.1. Initial Inspection

Unlike power windows, there’s no quick fix for manual windows. Attempting to force the window can worsen the problem.

1. Remove the window crank and door panel.
2. Inspect the components visually.

3.2. Checking the Window Crank

Pay attention to how the crank feels when turned.

• If it freewheels or grinds, the teeth may be stripped.
• Remove the crank and inspect the teeth.
• Replace the crank if the teeth are stripped.

3.3. Examining the Regulator

If the crank is fine, inspect the regulator and window.

• Ensure the window hasn’t popped out of its channel.
• Check for a bound or stuck regulator.
• Apply new grease to the regulator if the old grease has dried out.
