VW EOS Auto Windows Not Working: How to Troubleshoot

If you own a Volkswagen EOS, you may understand the importance of having fully functional auto windows. It’s a convenient feature that adds comfort to your driving experience. However, sometimes you may experience the auto windows not functioning.

For automatic windows to stop working, the first step is to check the fuse box for any blown fuses. If the fuses are okay, the window motor must be replaced. It is best to have a professional mechanic diagnose and repair the issue.

In this guide, we will discuss how to troubleshoot the auto windows issue in VW EOS. Whether it’s a simple fix or a more complex problem, read on to find out how to get your auto windows back in working order.

Causes of Auto Windows Problems in VW EOS

Unfortunately, there are times when the auto windows on the EOS can stop working. Here are some common causes this problem:

  1. Dead Battery: A dead battery is one of the most common causes of auto windows issues in a VW EOS. The windows may not function if the battery does not provide enough power to the electrical system, the windows may not function.
  2. Fuse Problems: Blown fuse is another common of windows issues. It causes the electrical system to stop working and prevents the windows from operating.
  3. Wiring Problems: Wiring problems can also cause the windows to stop working. Damaged or corroded wiring can cause an electrical system failure, preventing the windows from functioning properly.
  4. Window Motor Failure: The window motor is responsible for moving the windows up and down. Motor failure reasons the window not to work.
  5. Window Switch Failure: A switch is responsible for controlling the movement of the windows. Failed switch stops the windows from working.
  6. Window Regulator Problems: Regulator is responsible for controlling the movement of the windows. A ruined regulator obstructs the windows from working.
  7. Power Window Control Module Problems: The power window control module controls the movement of the windows. A damaged module hinders the windows from working.

Tips to Troubleshoot VW EOS Auto Windows Problem

If you are experiencing issues with your Volkswagen EOS auto windows, it is important to troubleshoot the auto window issue to ensure proper vehicle operation. Here are some troubleshooting tips to help you get your windows working properly again:

Checking Battery Voltage

  • Jumpstarting the Car: Jump-start the car to check the battery voltage. First, ensure both cars are turned off, and their keys are out of the ignition. Then, connect the positive cable of the jump starter to the dead battery’s positive terminal and the other car’s positive cable to the jump starter’s positive terminal. Connect the negative cable of the jump starter to the negative terminal of the other car and touch the negative cable to any metal part of the dead car. Start the car with a good battery and let it run for a few minutes. Then, start the dead car and check the battery voltage using a multimeter.
  • Testing Battery Voltage with a Multimeter: Check the battery voltage for an auto window not working in a VW EOS. Use a multimeter to measure the voltage of the battery. If the reading is below 12 volts, it indicates a weak battery and needs to be charged or replaced. Reading above 12 volts suggests a problem with the window’s electrical system, and further troubleshooting is necessary.

Replacing Fuses

  1. Locating the Fuse Box: The fuse box for the power windows in a VW EOS is located under the driver’s side dashboard.
  2. Identifying The Power Window Fuse: Power window fuse for the VW EOS is located in the fuse box in the engine compartment. A Fuse label indicates which fuse controls the power windows.
  3. Replacing the Fuse: Find the correct fuse for the windows in the fuse box, remove the old fuse, and replace it with a new one of the same amperage. It’s important to follow the proper procedures and precautions to avoid any electrical damage to the car.

Inspecting the Power Window Switch

Testing the Switch with a Multimeter: To test the power window switch with a multimeter in a VW EOS, follow these steps:

  1. Remove the switch from the door panel.
  2. Turn the multimeter to the “Continuity” setting.
  3. Touch one probe to the power supply terminal on the switch and the other probe to the control terminal.
  4. If the multimeter reads a continuous circuit, the switch is functioning properly.
  5. The switch must be replaced if the multimeter does not read a circuit. The power window switch controls the power Windows, and if it is not working properly, the auto windows will not be able to function.

Examining the Window Regulator

  • Checking for Loose or Broken Parts: This involves examining the window regulator to ensure that all parts are securely attached and functioning properly. If any parts are damaged, they need to be replaced to restore the proper operation of the window system.
  • Replacing the Regulator: Replace the regulator if the auto windows are not working in a VW EOS. A mechanism in the regulator moves the window up and down. Remove the door panel to replace the regulator, and disconnect the regulator from the wiring harness. After that, install the new regulator and attach the door panel.

Replacing the Window Motor

  • Removing the Door Panel: To remove the door panel in a VW EOS, unscrew any screws or fasteners holding the panel and gently pry the panel off the door frame. This will give you access to the window mechanism and inspect and repair it if necessary.
  • Accessing the Window Motor: You should be able to see the window motor and its connections inside the door panel. Disconnect the electrical connections, and remove the bolts that hold the motor in place. In this way, you will have access to the window motor.
  • Replacing the Motor: Then, install the new motor, reconnect the electrical connector, and reattach the door panel. It’s best to refer to a repair manual or seek professional assistance.

Tips to Prevent Auto Window Problems in a VW EOS

Regular maintenance is essential to maintain your windows’ integrity. Without proper maintenance, your windows can suffer from several issues, such as air leaks, condensation, etc. Here are some of the reasons it’s important to keep up with regular maintenance for your windows:

  • Preventing Damages: By performing routine checks, any potential problems or damages can be identified and repaired before they escalate into bigger issues.
  • Avoiding Costly Repairs: Regular maintenance helps prevent costly repairs, saving money in the long run.
  • Prolonging Lifespan: It helps prolong the windows’ lifespan, making them last longer and perform better.
