The heating is not working in my 323i. It seems I'm not
getting any voltage to the heat valves. I've probed the output from the control unit and it pulses between 0v and 13v as expected. When I measure it at the heat valve connector I get the 13v supply but almost 0v at the control pins continuously. I've tried pulsing ground to the valve and i can hear the solenoid moving (very faintly). This would suggest a break somewhere between the control unit and the heat valve. I tried a resistance test between the control unit connection (and what should be the same piece of wire) at the heat valve and strangely its 0.8, not quite 1 but not quite 0 either. Any suggestions on where to go with this next? Edited by quarryman |
