Power Window Regulators Repair and Replacement
Restore the comfort and functionality of your vehicle with our Power window Regulators repairs.
Electric window systems provide everyday comfort and convenience. But over time, internal components can wear out or break down: tired motor, faulty switch, severed cable… Our team specializes in the repair and complete replacement of these mechanisms , to restore your windows to their smooth and secure operation.



When should you have your power windows checked?
Here are the telltale signs of a malfunction:
- Window no longer goes up or down
- Jerky, slow, or stuck movement
- Creaking or rubbing noise in the door
- Switch no longer responds
- Window slides or falls into the door
Never force a stuck mechanism: this can further damage the motor or cable .

Do I need to replace the entire system if my window stops working?
Not necessarily. We perform a precise diagnosis to target the component that needs replacing (motor, switch, cable, etc.).
Can I continue to manually operate a faulty power window?
No, it is strongly recommended not to force the window. This can irreversibly damage the internal mechanism .
Is this covered by my insurance?
Generally, electric window failures are not covered by the glass breakage warranty. However, if the failure is the result of an accident, partial coverage is sometimes possible.
Do you use OEM parts?
Yes, we prefer OEM to ensure compatibility and durability.
Can I have just one window repaired?
Yes, each window can be repaired individually. However, if the breakdown occurs on several doors, we offer attractive group packages .
