I have a 1990 BMW 730i. german spec. Yesterday when i came to work i rolled down the driver window. When I tried to roll the window up, it would not work. I tried all the other windows and they would not work either. Pushed the lock button, that did not work either. When I got out of the car and tried to lock the door with the key, the central locking system did not work either. I also noticed that the windshield wiper would only work in high speed. I replaced the fusible link and checked the fuses to no avail. Can anyone point me in the right direction. I tried swaping the ZKE computer with one from the salvage yard. That did not work either. ( maybe the one at the salvage yard was bad). Any help would be greatly appreciated.
Also I had a BMW dealership here in germany check the obvious stuff.(for free, believe it or not).. they suggested (free of charge) that it may be the Central Body module (ZKE). Does anyone know about this?
