If your car window is moving up or down very slowly, it usually points to a problem with the window regulator, motor, or track alignment. Dirt, lack of lubrication, or electrical faults can also contribute. While the window may still work, ignoring the issue can lead to complete failure, leaving the window stuck open or closed.

What does it mean if a window moves slowly?

A slow-moving window indicates resistance in the regulator mechanism or weak power delivery to the window motor. This makes the window struggle to move smoothly, especially in colder weather or after extended use.

Common causes of slow window movement

• Failing or worn window regulator
• Weak or failing window motor
• Dirt, debris, or lack of lubrication in the window tracks
• Electrical issues such as weak wiring or failing switches
• Cold temperatures thickening grease in the tracks

Why do you need to fix this problem quickly?

If not addressed, the window may eventually stop working altogether. This can compromise security, convenience, and safety — especially if the window gets stuck open in poor weather.

How do you know when to get it checked?

You should book an inspection if:

• The window moves noticeably slower than usual
• The window stops mid-way or struggles to close
• You hear grinding or clicking noises when operating the window
• Other windows in the car operate normally, ruling out electrical supply issues

What happens during an assessment?

A mechanic will:

1. Test the window motor and switch for proper electrical function
2. Inspect the window regulator and track alignment
3. Clean and lubricate the window tracks
4. Check for wiring or switch faults
5. Advise on regulator or motor replacement if required

How much does it cost to fix?

Cleaning and lubricating tracks may cost $80–$150. Window regulator or motor replacement typically costs $300–$700 per window, depending on the vehicle.

Is it unsafe to drive with a slow-moving window?

Not immediately unsafe, but it can become a problem if the window fails completely. This could leave the car exposed to theft, weather, or prevent window operation in an emergency. It’s best to have the issue repaired promptly.
