What does a window regulator do?
The window winder mechanism, or to give it it’s correct title, window regulator, is the means by which the side windows are moved up and down.
How does the window regulator work and what are the components?
When the window mechanism is activated, either buy an electric switch or by a manual handle, the regulator wires will start to wind one way or another depending in the desired direction of up or down. This winding motion will pull the wires that are attached to a clamp which holds the glass. The glass will then move up and down accordingly within the slide channels in the door frame.
If the mechanism is a scissor type, then the same is done via a toothed cog section on the end of an arm, which is attached to the glass clamp,
Typical symptoms that require a window regulator to be replaced.
Electric Windows
- When the window does not open or close when using the switch but you can hear the motor running (please see note).
- When the window has dropped into the door.
- When the window's movement is unusually slow.
- When the window does not go down or up all the way.
- When an excessive squeaking or crunching noise occurs when opening or closing the window.
- When the window goes up partially, then drops back down again.
Manual Windows
- When turning the handle, nothing happens.
- The handle becomes very stiff to operate.
- The window will only partially open or close.
- The window drops down into the door.
NOTE
If you hear no buzz from the motor it is more likely that the electric motor has failed. In many cases though, it might be just the switch that has failed or it might be that the system has blown a fuse.
Should you experience problems with an electric window then it is advisable that you have it inspected as soon as possible and, if necessary, have the window regulator replaced. As the regulator is, in most cases, part of one assembly with the electric window motor it might be necessary to replace this whole unit.

FAQ’s
Can I supply my own parts?
No, we will not fit customer supplied parts unless they are a brand new item, purchased from a dealership with the receipt as proof of purchase. There is no flexibility over this due to insurance and warranty issues.
What happens if the mechanic finds that the window regulator doesn’t require changing and the problem is due to another issue?
In this scenario, the mechanic will provide a no obligation quote for the correct repair. Should you accept this, the mechanic can alter the booking accordingly. If you decide not to go ahead with the alternative repair, the mechanic can change the booking to a call out and diagnostic booking and charge according to the time spent with the vehicle and call out.
