Common Causes of Volkswagen Window Regulator Failures

Does your Volkswagen have a faulty window regulator that makes it hard to roll the windows up or down? The window regulator is a major component of the power window system, helping to move the glass up or down when the switch is pressed. When it fails, you may find yourself unable to open or close the window.

What Causes a Volkswagen Window Regulator to Fail?

• Broken or Stretched Cables: Most Volkswagen window regulators use cables to move the glass up and down. These cables can become frayed, stretched, or broken over time, and when they wear out, the window may become jammed or drop into the door panel.
• Worn Out Motor: Another possible cause of window regulator failure is when the motor has become worn out. The window regulator is a mechanism that uses a small electric motor to move the window up and down. This motor can wear out due to excessive usage, electrical issues, or normal wear and tear over a long period of time. If the motor becomes faulty, then your windows will take a longer time to open or close, or they may not move at all.
• Faulty Window Switch: There are occasions where the problem is not with the regulator but with the window switch that controls it. A faulty switch can block the supply of power to the motor and make it appear like the window regulator is faulty. If the switch does not work or only works sometimes when pressed, then the switch may need to be replaced.
• Misaligned or Damaged Tracks: The window glass slides up and down in tracks that are installed in the door. If these tracks become dirty or worn, or if they are bent or misaligned, then the window regulator will encounter resistance when attempting to move the glass. In the long run, this puts a lot more pressure on the motor, causing the motor to burn out or make other components of the regulator break down.
• Electrical Problems: Since the window regulator is operated by an electric motor, any larger problems that affect your Volkswagen’s electrical system will also likely affect the performance of the window regulator. Sometimes it can be bad fuses, loose contacts, or damaged wires that keep power from getting to the regulator, and this will prevent the system from functioning properly.
• Moisture and Corrosion: Rainwater may sometimes penetrate into the door panel through small cracks and crevices. When water seeps into the door, it results in corrosion of the metal part of the window regulator, making it stiff or even causing it to jam completely. If your Volkswagen has been exposed to a lot of moisture, then it is recommended to inspect the regulator for signs of rust or damage.

Why You Shouldn’t Ignore a Failing Window Regulator

• Discomfort: Having a window that is stuck in either an open or closed position is uncomfortable in many situations, like when trying to pay at a drive-thru, using a parking garage ticket machine, or even just getting fresh air. It is always best to get any window issues fixed as soon as possible so that they do not cause further problems in the future.
• Safety Issues: A faulty window is not just an inconvenience; it can even pose a threat to the occupants of the vehicle. If your windows can only be opened partially, or are stuck in certain positions, your vehicle becomes exposed to theft, bad weather, and flying debris.

How Mechanics Resolve Volkswagen Window Regulator Problems

A professional technician will first assess the window regulator, motor, switch, and wiring to identify the cause of the failure. If the regulator is damaged to the extent that it cannot be repaired, then it will have to be replaced. This procedure entails gently taking out the door panel, disconnecting the bad regulator and installing a new one of superior quality.
