Window mechanisms

In the device of the car, the side windows are an indispensable part. Performing functions such as smoothly opening and closing them or locking the glass in a certain position becomes possible with the help of parts called glass lifters or glass lifters – it is their correct operation that ensures the mechanical or electronic regulation of the level of the glass. “Mikron Docev” repairs window regulators of all types of cars, regardless of the type of the part in question.

What are window lifters?

Window regulators fall under the category of auxiliary and secondary car parts, but without them it would be impossible to adjust the level of the side windows. This is their main function – they ensure that the raising and lowering of the glass is done slowly and smoothly, as well as locking it in the position desired by the passenger or the driver. They are also directly responsible for achieving hermeticity in the vehicle. Thanks to them, it is possible to let fresh air into the passenger compartment without having to open the doors – something that is really dangerous and highly inadvisable when driving.

What types of window lifters are there?

Although their function sounds rather one-sided, this does not mean that there is one type of window lifter that we find in all cars.

In terms of where the part is installed in the car, we know left and right, front and rear, according to the respective door in which the mechanism is installed.

From the point of view of the drive of the windows, we mainly know two types of window regulators – mechanical and electric.

• Mechanical window regulators work through the well-known cranks that the passenger or driver turns in the corresponding direction – this raises or lowers the glass of the corresponding door;
• Electric windows are found in newer models of cars – they are undoubtedly much more convenient to use, since it is required to press a button that adjusts the level of the glass. Whether mounted via a lift or lower motor or a motor block, these mechanisms are definitely preferred by car owners;

The lifting mechanism of the window regulator itself also comes in different varieties. In both mechanical and electric ones we find a rope. For rope, the so-called wire for window lifters, which are metal flexible braids. Through a toothed gear, the movement of the rope is carried out and thus the level and locking of the glass in the desired position is adjusted.

Lever window regulators operate on the principle of a drive mechanism and a system of levers and rack and pinion. A roller is attached to the end of the lever, to which a gear transmits the specified movement from the handle or the motor. This is how it is raised and lowered, and the glass is locked in one position thanks to a spring-loaded locking mechanism.

Rack window regulators are famous for their relatively simple device – in them, a gear is attached to the rack, and the torque allows the mechanism to move along it.

What are the advantages of electric windows?

We mentioned that electric windows are on the next level and are definitely preferable to mechanical ones. Gradually, even the control with a button has been replaced by an electronic system that allows the integration of a set of options and extras, which additionally provide more options and comfort for the driver and passengers. Some of these extras concern the automatic raising of the windows when locking, stopping their movement during road bumps, as well as blocking the windows, if the situation requires it.

What are the signs of an broken window lifter?

Given the nature and functionality of the mechanisms, the problems you would encounter in the event of an injury concern the smooth and working movement of the glasses. If you notice that they do not move, box or stop, then this is a definite sign that the window lifter requires timely diagnosis. Given their location and the requirement to remove the door’s bark in order to reach them, we do not advise you to undertake this undertaking yourself. Visit us – we will carry out a thorough diagnosis and, if necessary, we will repair or replace the damaged window lifter with a new working mechanism. Trust the professionals with rich experience.
