The window regulator is an important part of a Mercedes vehicle because it helps the power windows work properly. There are so many moving parts to the window regulator that if pieces begin malfunctioning, oftentimes the whole regulator needs to be replaced. If the window regulator does fail, you will notice very specific signs and symptoms. Some common signs that your window regulator needs to be repaired or replaced are listed below.
The Window Becomes Stuck
If your window is having trouble rolling up or down, it could be due to your window regulator. If you hear a motorized sound when you try to roll the window up or down but it won’t budge, it’s also possible the window has fallen off track. Having a specialist take a look at your window and its regulator can help determine what the underlying issue truly is.
The Window Speed has Changed
A tell-tale warning sign that the window regulator is malfunctioning is if the window is rolling more quickly or more slowly than usual. If this is happening, then getting the regulator replaced or repaired will likely be necessary.
There are Strange Noises Coming from the Window
If a window regulator has failed, oftentimes it will make a clicking or grinding noise. If you are hearing this noise, get your Mercedes vehicle checked as soon as possible to find out what repairs need to be done on the window and the regulator.
The Window Button Stops Working
Modern technology allows us to push a button and our window rolls down automatically. Long gone are the days of the cranking down the window. However, the window regulator is what makes this possible, and if it malfunctions, then the button will no longer serve its purpose.
Another cause of this could be due to an electrical failure. It’s important to get a proper diagnosis from a professional mechanic in order to determine the cause and fix the issue.
What Causes Window Regulator Issues to Begin With?
If you have noticed any of these issues indicating window regulator failure while driving your Mercedes, you may be wondering, how it happened and what causes the window regulator to malfunction. Some of the issues concerning window regulator failure can include:
- Cold weather: What is the climate like in your city? If you live in an area that is often below freezing, this could freeze your regulator, preventing proper function. By taking precautionary steps, such as keeping your car covered or letting it run for a bit if you know it’s going to be sitting for a while, you can prevent your regulator from freezing.
- Separated cables: Another important factor to getting your windows to roll up and down are special attached cables. If they come apart, you will experience issues with your window function. In fact, cable detachment is one of the main reasons for window issues. Make sure you contact a skilled specialist to get the repair done right and avoid further complications or damage.
- An overheated motor: Specialized motors are what open and close the windows of your Mercedes vehicle. If these motors experience temperature malfunctions, this can impact your car’s window function. Make sure you are regularly monitoring the temperature of your vehicle, and ask your mechanic to check the temperature levels to avoid a costly repair.
