The window regulator in the car is an integral part of comfort. Regardless of the mechanism or device, the purpose is the same, lower or raise the glass. Power windows are considered the most popular, but everyone can fail. If you figure it out, then the repair is not so difficult.
The concept and types of windows
Each car has built-in special devices that serve to adjust the height of the glass. They are called power windows. The main parts of this device are considered to be the drive, the seal, the lifting mechanism and the grooves.
There are several types of power windows, depending on the type of built-in drive. The first type is called electric. It is based on the electronic control of raising and lowering the glass using a button. This type of window regulator is usually installed on modern cars, including Mercedes C-Class cars. The second type is mechanical. The name speaks for itself. To adjust the glass level, you need to scroll a special lever. These windows are mainly found in older cars.
Also, the electric window is divided into 3 subtypes. The first of which is called cable. The principle of its operation is that the glass is lowered or raised using a special cable. This is a fairly common subspecies of window regulator, and therefore it is not so difficult to find spare parts for it. The second subspecies is called rack and pinion, and according to the name, the movement occurs along special slats. Rack windows last longer than other types.
However, special care is required for them, namely from time to time to fill in a special lubricant. And finally, the third subspecies - lever, the essence of which is the movement of the gear and plate. However, the very structure of the device leads to the fact that the speed of lowering or raising the glass is uneven.
General problems
A very common problem with power windows is their sinking. There are also times when there is difficulty in opening or closing the glass. When there are any problems with the operation of the power windows, it is necessary to check all the components and connecting mechanisms to find the true problem.
First you need to check the functionality of the fuses that are in the car under the rear seat. If everything is in order, then you should check the voltage of the switch in the door wire. If there is no problem, check the motor itself. Having tried all the options, you should finally start checking the window regulator mechanism.
Repair of windows Mercedes C-Class
Depending on the type of windows, the repair will be carried out in different ways. First of all, we will consider the most popular electric windows. In case of a stuck, the Mercedes must be started before starting the check. After that, lower the glass, holding it for about 2 seconds.
Then, do the same only in the opposite position. Close the glass manually by holding it for 2 seconds. After all this procedure, turn off the car and after a few seconds, activate the power windows again. After this process, they should work without any hindrance. The second common problem that can be found in Mercedes cars is jamming when lifting the glass. There are several reasons for this. One of the options for problems is trash that has got there. It is also possible to distort or displace any part. There are several options to fix the problem. The first is to lubricate the mechanism. Since the debris causes the parts to rub against it, this can lead to their breakage. Therefore, gently lubricate the glass frame and check the device. Repeat this procedure to get the grease inside.
However, if this does not help, you should mechanically inspect the window regulator device. Remove the trim and visually inspect every detail. They should be free of any bends or damage. At this stage, you can also adjust the mount, as often the problem can be a weak or, on the contrary, too strong mount.
If all the procedures done did not give the desired effect, all that remains is to reinstall the power window. To do this, we completely disassemble the mechanism. First remove the upholstery panel, lower the glass and disconnect the wiring from the minus mark. Then lift and disconnect the wires from the terminal. Take care of releasing the mount. To do this, unscrew all the bolts and pull out the device itself. After all, replace with a new one, collecting all the parts in reverse order.
The mechanical window regulator is also often problematic. First of all, when the windows are operating, noise or knocking can be heard, which prevents the glass from lifting. In this case, check the teeth by lifting the glass up with your hands. If they are broken, their shape should be corrected.
There are also times when the cable breaks. In this case, it cannot be repaired and the only solution is to replace it. To do this, unscrew the power window mounting bolts, and moving the engine away, wrap the cable over the clips. After that, it is necessary to lubricate all parts for their long-term and efficient operation.
And finally, another problem with the window regulator in Mercedes C-Class cars may be the scrolling of the handle. The reason most likely lies in the unusable condition of the gear. To do this, remove the trim, unscrew the handle frame and unscrew the handle itself. Next, visually inspect the gear, in case of its poor condition, replace it with a new one.
Repair cost
The price of power windows for Mercedes C-Class cars is influenced by their quality, manufacturer and type of mechanism. The average cost of the entire kit will range from $ 35 to $ 100. It is often worth remembering that the parts are not sold separately, but if you take additional repairs, then in addition to spare parts, you will need to pay about $ 20 for the work.
