my Volkswagen Tiguan First Generation (2007-2018) power windows stopped working how to fix

Solution

1. Preparation

• Gather tools: OBD-II scanner, multimeter, socket set, screwdriver set, and wire connectors.
• Disconnect the negative battery terminal to ensure safety during repairs.

2. Fuse Replacement

• Locate the fuse box, typically found under the dashboard or in the engine compartment.
• Identify the power window fuse using the fuse box diagram.
• Remove the blown fuse with a fuse puller or pliers and replace it with a new fuse of the same amperage.

3. Switch Replacement

• If the switches are faulty, remove the door panel:
  • Use a screwdriver to remove screws securing the door panel.
  • Carefully pry off the door panel using a trim removal tool.
• Disconnect the electrical connector from the power window switch.
• Replace the switch with a new unit, reconnect the wiring, and reassemble the door panel.

4. Motor Inspection/Replacement

• If the switches are functioning but windows still do not operate, proceed to inspect the window motors:
  • Remove the door panel as detailed above.
  • Unplug the motor connector.
  • Use a multimeter to check for voltage at the connector while pressing the window switch.
  • If voltage is present but the motor does not operate, remove the motor by unscrewing it from the regulator.
  • Replace the motor with a new one, reconnect the wiring, and reassemble the door panel.
