BMW750 electrics - Ian
My 1991 750 bmw has developed a fault. The central locking has stopped working and so has the sun roof and the windows, presumably because they are on the same circuit for closing up when the key is turned in the drivers door. All fuses seem ok and the relays, as far as I can check the, are ok. Any advice would be helpful. or a contact for a switched on auto electrician in south coast area. My regular service guy, who is terrific, by his own admission is useless on electrice. Any help?
