The window regulator, or window mechanism, assists in opening and closing the side windows on the car. Most cars nowadays are fitted with an electric regulator, which is controlled by a window switch on your door or dashboard. Cars with basic trim levels and older cars are usually operated by a manual mechanism. In that case, the door is fitted with a window winder.
What parts does the window regulator consist of?
The window regulator is fitted inside the door underneath your window. It consists of a bracket that holds the glass in place and the actual mechanism. On some cars this is a ‘scissor’ type mechanism, on other cars this is a cable-type window regulator. Attached to that is either the window motor or a manual window winder, depending on your car.
With a ‘scissor’ type, or gear driven regulator the mechanism the X-shaped regulator part will effectively close itself as the window is lowered. When the window needs to close again it will return to its normal position pushing the window back up.
The cable-type regulator on the other hand consists of the bracket that holds glass which is moved across a sliding bar inside the door by the cables. As the bracket moves up and down the door window glass is closed and opened respectively.
How To Diagnose Window Regulator Problems
Sometimes problems can occur with the mechanism itself. Or if you have electric windows, with the electrical parts of the regulator. It can be tricky to get to the bottom of the problem. So if you’re not sure make sure to get an inspection first, so that a mechanic can select the right parts.
