Hi I own a 1991 BMW e34 525i se auto RH drive. Just recently the interior electrics have started playing up. When the car has been driven for a few miles the electric windows, interior lights, alarm, c/locking, windscreen washer all stop working even though the dashboard lights/instruments, and engine, exterior lights are unaffected. When the car has cooled down it all starts working again? does anyone know which relay or master fuse (perphaps a crack) controls all this lot?

Thanks

Rich
