Window regulators are a key part of your home’s energy efficiency. If you want to learn more about them, this article is the place for information! We’ll cover how does a window regulator work and how often it should be serviced so that everything runs smoothly at all times in future years when these controllers need replacement or repairs due to an unclean environment which causes corrosion on its parts (a major no-no).

Operating principle

The window regulator works on the basic principle of measuring the current in a circuit. An electric window regulator measures the current on both ends of a sampling resistor, and the real-time current is calculated during motor operation. This current is then fed into a microcontroller (MCU), which divides it into two parts. One part is used for anti-pinch and locked-rotor detection, and the other part is processed by a software algorithm.

There are various types of window regulators. Some of them are designed to control four windows simultaneously. They can detect the motor current in real-time and use the ripple in the current to calculate the operating position of the window. The intelligent anti-pinch function of these window regulators is based on the motor current detection. Another type of window regulator can detect the position of an open window and close it automatically.


Window regulators come in various types. There are manual and automatic types. Manual ones require you to apply pressure to the window to open it or close it, while automatic ones operate automatically and do not require manual adjustment. They are usually made of metal, and they are the oldest types. They are also the most popular, as they are the easiest to use.

A power window regulator is one type that can be converted to a manual one. It has a motor that is fixed to a stationary part in the door panel. This motor then transmits power to the window glass, and the transmission mechanism has many parts. As a result, it occupies a large space inside the door panel.


The window regulator is a device that controls the size of the opening of a door window. It is designed to be smooth to operate and includes cable tension springs to prevent cable reels from binding. The device is mounted on a track and is connected to the window by a plate. A window regulator’s main advantage is that it is easy to maintain.

Window regulators come in different styles and constructions. Some use a lever, while others use a rack and pinion mechanism. The most common type is a cable lifting mechanism, though there are also other variations.


When you need to repair a window regulator, you need to take special care to avoid damaging the parts. In some cases, the motor inside of the window regulator might be bad, so you will need to replace it. You also need to clean and lubricate the channel and track where the window regulator runs. If you have a new window regulator, you might need to reset it using a scan tool.

To do this, you need to remove the window regulator. If it is stuck from the outside, you can use a piece of sticky tape to hold it up. Be sure that the tape stretches from the bottom of the window up, and goes over the window frame.
