How does a windows regulator work?

The window regulator is the mechanical assembly that moves a window up and down when power is supplied to an electric motor or, with manual windows, the window crank is turned. Regulators are often riveted to the door, so they’re not easily removed or replaced.

How do you adjust a window regulator?

Locate the two jack screws at the bottom of the window regulator, and turn them to adjust the window’s tension against the car frame. Turning the jack screws clockwise will draw the window closer to the frame of the car; counterclockwise will push the window toward the street.

What is the difference between a regulator and an actuator?

‘Regulator’ is the older term used commonly with manual-operating windows to describe the gear-and-quadrant assembly a window crank operates. ‘Actuator’ is the normal term for the cable-and-pulley or scissors assembly operated by a power-window motor, and in fact the motor and ‘actuator’ may come as one piece.

What does a bad window regulator sound like?

If the window is able to move and you hear strange noises, this could be an early warning sign of a failing regulator. The noises may sound like grinding, clicking, or chattering.

Why do window regulators fail?

The window regulator can overheat from excessive use and stress over time, which can lead to a complete failure of the regulator. If a motor starts to overheat, the best practice would be to let it cool down before trying to use it again. Freezing temperatures can cause a window to disconnect from a window regulator.

How long do window regulators last?

In many cars, window regulators last the car’s lifetime. However, unexpected failures can occur, typically after 100,000km, that require window regulator replacement. On average, a new window regulator will cost between $300 and $450 and sometimes more, depending on the make and model of the car you drive.
