You should try another thread for the window and mirror. The window motors on this car are on the CAN bus, the seat motors are not. The window "motors" do die mysteriously. I had a rear one do that (another thread). I say "motors" because the motor itself is fine, but the circuit board integral to it is not. But my board looked fine so it is nothing that can be fixed. I recommend a junk yard for a replacement. As for the mirror, I think the wires in the mirror head can break, but I never had any problem. Again, search for that. Different thread. Seats here.
