lol if you press the window button and hear a click the the window motor needs to be changed.
if you press the window button and hear a electric motor sound the ur window motor is good and the amp is bad.
If you hear a click but no window movement then thats ur window amp working and not the motor. so window motor needs to be replaced, you said you hear a electric sound so im guessing thats the window motor and ur window amp is dead.
