Window Regulators

How to Diagnose and Replace a Volkswagen Window Regulator


Bookmark and Share

If the windows in your vehicle are broken or seem to be stuck in one position, you may have a problem with your Volkswagen window regulator. The window regulator is the system that's responsible for maneuvering the windows up or down. While most updated vehicles from the Volkswagen manufacturing line have automatic and electrically powered systems (the Jetta window regulator is a prime example), some older vehicles may have manual systems that require the turning of a hand knob on the inside of the door to open or close the windows. In order to complete the process of Volkswagen automatic window repair in a newer vehicle with an electrically powered system, read on for a step by step guide.

Tools and Materials Needed:

  • Screwdrivers of different sizes
  • Prying tool
  • Volt meter
  • Replacement regulator that matches the one that's already in your Volkswagen

Step 1 - Assess the Problem

Begin by attempting to learn more about the problem. Check all of the windows in the car to see if some of them are functional. If all of the windows seem to be stuck, it's likely that there's an electrical problem with the window regulator system; this may include a blown fuse or a connection out of alignment. This problem is typically easy to solve and doesn't require a full replacement of the regulator.

If some of the windows will work and others won't, attempt to open the windows that are stuck and listen for sounds of the window regulator motor working inside the door. If you're able to hear it, you may have a regulator that has fallen out of alignment with the gears that move the windows. This is another problem that doesn't typically require an entire replacement.

Step 2 - Open the Car Door Panel

Remove the screws that attach the car door panel to the door itself. Use the prying tool to carefully remove the plastic door panel and set it aside. Visually inspect the regulator system that is attached to the door; look for signs of any blown out components or disconnected wires. If possible, replace any damaged smaller components of the regulator system. Check to see that there's electrical current flowing to the circuit with your volt meter.

Step 3 - Replace the Regulator, If Necessary

If you find that it's necessary to replace the regulator, begin by removing the two bolts that attach the system to the car door. Carefully disconnect the regulator and set it aside. Follow the installation instructions on the new regulator in order to properly replace it. Be sure to check that the electrical circuit is complete before putting the car door panel back on.

If you have any other questions, or if this process does not fix the problem, consult with a mechanic.
