I have found the fault (I think) on my air con, Car is a 1988 760 turbo estate, but don't seem to be able to turn off the flashing green light in the cabin, so I assume there must be a reset sequence for this? If so, does anyone know where it is? Or what it is? I have tried the obvious, taking off the battery for a day....
Fault was wires off the external air temp sensor.
