How can I fix an issue with the power windows in my Audi 80?

One of the power windows in my Audi 80 seems to be stuck and won't go up or down. What could be causing this problem and how can I fix it?

It is possible that the issue is with the window regulator or the motor. You may need to replace one or both of these components to fix the issue.

Check the fuse for the power windows. If it is blown, replace it with a new one. If the new fuse also blows, there may be an underlying electrical issue that needs to be addressed.

Make sure the window switch is working properly. Sometimes a faulty switch can cause issues with the power windows. If necessary, replace the switch with a new one.
