Hi All,
I bought my 2004 CL9 Luxury about 8 months ago, air con worked amazingly then about 3 months ago it completely stopped working. None of the buttons (fan up/down, ac on/off, front and rear defog) register at all when pressed. We have checked all fuses and hard reset the head unit (which I should mention is one of those stupid all in one Jap knock off cd/usb/ipod/sat nav/air con replacement jobs ) The weirdest thing is that at the exact same time that this all failed, the outside temp readout on my dash stopped working too.
My belief is that the main issue is the knock off head unit has blown an on board fuse or something (every part of it works except the air con buttons, which still light up). We have bypassed the head unit so the fans still work, they are just constantly on full bore. Or could it have something to do with the outside temperature sensor failing and that has somehow stopped the ECU from receiving the signal from the head unit?
Any help or suggestions on where to go next much appreciated
