air con clutch or control module fault???
iv had no aircon since i purchased my a3 over a year ago
when i switch the aircon on (econ off) the second fan at the rad comes on, but the clutch for the compressor does not come in
i have got the plug off of the compressor and measured the voltage across it, it seems to be a constant 9 ish volts regardless of the air con being on or off, and when switched on the volts rise to 10v for moment and then back to 9v
i have not been able to get to the connections on the compressor to check the coil (assuming there is one in there???)
i dont get any vagcom faults when scanning the car relating to aircon, is there anything else i can check?
