If your power window is noisy when moving up or down, it usually indicates wear in the motor, regulator, or window tracks. While the window may still function, ignoring the noise can lead to complete failure, leaving the window stuck open or closed. Addressing the issue early helps avoid more expensive repairs.

What does it mean if the power window is noisy?

Noises such as grinding, squeaking, or rattling when operating the window suggest mechanical or electrical wear. The problem may be minor, such as dirt in the tracks, or more serious, such as a failing regulator or motor.

Common causes of noisy power windows

• Worn or failing window regulator
• Weak or damaged window motor
• Dry or dirty window tracks
• Loose glass or mounting hardware
• Broken or worn-out guide clips or rollers

Why do you need to fix this problem quickly?

A noisy power window is a warning sign that parts are wearing out. If left unchecked, the window may stop working completely, get stuck open, or damage other components, leading to higher repair costs.

How do you know when to get it checked?

You should book an inspection if:

• You hear grinding, squealing, or rattling when the window moves
• The window moves slowly or unevenly
• The glass vibrates or feels loose inside the door
• The noise is getting louder over time

What happens during an assessment?

A mechanic will:

1. Inspect the window motor, regulator, and tracks
2. Check glass alignment and mounting hardware
3. Lubricate tracks and moving parts
4. Replace worn or faulty components such as the regulator, motor, or clips
5. Test the window for smooth and quiet operation

How much does it cost to fix?

Lubricating and adjusting the window may cost $100–$180. Regulator replacement typically costs $250–$500, while motor replacement may cost $300–$600 depending on the vehicle.

Is it unsafe to drive with a noisy power window?

It’s not usually unsafe, but it can quickly lead to the window becoming stuck open, leaving your car exposed to theft or weather damage. Repairing it promptly prevents further problems and higher costs.
