Hi

I have a problem with my 1989 525iSE. I have lost the use of the windows,sunroof and wipers. The problem seems to be with the control units. Are the control units for this equipment the 2 situated under the rear seat? One is a GM unit and the other is BMW.

I have traced the wires from the window switch back to this area and the cables/colours correspond. Am I in the correct area? Has anyone else experienced similar problems?

Any help is much appreciated.
