climate control pbm
I have a 98 A6Q 30V. The blower motor quits working after about 2 minutes. Everything is lit up OK, the air flaps all move, the A/C compressor is engaged when necessary. I've replaced the fan relay, the blower motor resistor, and the fan itself. It still craps out. I had a shop hook up VAG-COM to the car and it threw a 01273-17-00 (Fresh Air Blower [V2] Control Difference. He said he'd never seen that code before. I've torn my poor car's interior apart to trace a possible short, but everything seems to check out. Anyone have any thoughts? Something other than "it sucks to be you" would be helpful.
Thanks,

RE: climate control pbm
I was looking through the forums and found the post "Unlocking the Secrest within the Climate Control", and found that the codes don't match up with my unit. However, when I first turn on the car and then access the CC it starts rolling through 3 codes on it's own. They are:
left temp display shows "22" and the right shows "01";
left temp dislplay shows "06" and the right shows "04;
left temp display shows "13" and the right shows "04".
I am assuming that corresponds with the DTC codes of "22.1", "06.4", and "13.4". If that is the case, the first isn't true. The A/C compressor kicks in just fine. The second has to do with the engine coolant temp and a sporadic short - where would I look for that wiring? the third points to the footwell defroster flap motor potentiometer having a sporadic short.
BTW - the sunroof solar panel works fine. It apparently bypasses everything. But, not having a wiring diagram, I have not found its circuit.
Thanks for any suggestions.

I wish it were that easy. I have replaced the blower motor. I have also bench tested the old one (bought the new one anyway, just to make sure) and it spins right up no problem. I am starting to think I have a "ghost in the machine".

I seen some where the A/C has to be programmed but I don't have that data, but you could check fuse F5 15 amp in dash facia end which is the blower motor timer relay, all realys are in the foot well area
