The Pitfalls of Having a Bad Window Regulator in Your BMW

No luxury German carmaker manufactures vehicles as reliable and efficient as BMW... and, that's a fact. It is also true that vehicles, like any other artificial things, do have some vulnerabilities. Today's blog post highlights one such weakness in BMW cars; window regulator failure. So, if your BMW's window regulator has given up, this article will prove useful.

BMW Window Regulator Failure: Possible Reasons

There can be many reasons for a vehicle's window regulator to malfunction; the below discussion sheds light on some of them. The discussion also provides the readers with some viable solutions to fix such issues once and for all. Let's start by discussing the major reasons why a vehicle's window regulator may fail.

Reason #1- Parted cable

One reason why your BMW's window regulator may have given up is that the cable that is tasked with facilitating the up-and-down movement of the window has become detached from one of the pulleys. Or, the pulley to which the cable is attached has become damaged. In any case, if your vehicle's window regulator is not responding to your command, the first thing that you should do is to have its cable professionally checked by a certified professional.

Reason #2- Faulty motor

Another common problem with a vehicle's window regulator is that its motor can fail or overheat due to excessive use. For those who don't know, let us tell you that because of an electric motor you get to control the up and down movement of your vehicle's window by simply pressing a switch. If the motor malfunctions because of a technical glitch or overheating, no matter how many times you press the control switch, it won't work.

Reason #3- Cold weather

Freezing weather can also cause your BMW’s window regulator to give up. The mechanism that gets your car windows going has all sorts of different parts. If any of these two parts freeze together due to icy weather, you will have trouble operating your car windows. No matter how many times you try, the window won't work. There is no technical glitch here... it is the weather that caused the problem and all you have to do to fix the problem is get rid of the snow.

Reason #4- Electrical issue

Be it the motor or the control unit; the mechanism that controls how your BMW window operates relies on electricity. If the power supply to one of its components gets disrupted because of a bad wire or a broken relay, the entire mechanism will stop working. So, if your BMW's window regulator has been acting up for quite a while now, have a technician check the relays and wires connected to its electrical system.

Reason #5- Rough use

Rough usage can also result in window regulator failure in a vehicle. It is not only the window regulator that will be affected by your poor usage, but other important parts of the car can also get affected due to bad usage. Therefore, if you do not want your BMW to suffer costly repairs, it is important that you treat it with the utmost care.

BMW Window Regulator Failure: Signs to Look For

Before your window regulator ceases to function, it will give off some signals. Listed below are a few of them;

1. One sign that your BMW's window regulator has given up is that the window refuses to remain rolled up.
2. Another important clue that you will get if there is indeed something off with your vehicle’s window regulator is the emergence of strange screeching and grinding noises when you try to roll the window up or down.
3. Are your window buttons not responding to your input? This may be a sign of a faulty regulator.
4. If your BMW window is moving up or down too slowly or quickly, it could also point to a broken regulator. Whatever is preventing your BMW's window regulator from functioning normally needs to be diagnosed and fixed.
