How do I troubleshoot a non-functioning power window on my Audi A2?

I have a 2005 Audi A2 and the power window on the driver's side is not working. When I press the button, there is no sound or movement. How can I troubleshoot and fix this issue?

First, check the fuse for the power windows. If it is blown, replace it and try again. If the fuse is fine, then the problem may be a faulty window switch or motor. You can test this by using a multimeter to check for power at the switch and motor when the button is pressed. If there is power, then the motor may need to be replaced. If there is no power, then the switch may be the issue. It is best to have a professional mechanic diagnose and fix any electrical issues with power windows.
