Message I have a similar problem in a tt '91.

In my case, the compressor does not connect and neither does the fan. It only happens with A / C, the fan turns on if the motor needs it due to temperature. I removed the temperature sensor to check that it is ok. The same thing happens to you with the fan?
I did the a / c diagnostic test described in the manual, and neither does the compressor or fan start.

if I put a switch closing the relay circuits towards the negative pole, the compressor and the fan turn on.

If I activate the A / C and close the relay circuit, I have cold air in the car.

I checked the connections with a multimeter as the workshop manual indicates, and it seems that everything is OK.

I also changed the AC module, but unfortunately, the one I bought is a reference to a more modern model, I am waiting for another to arrive now.

I apologize for my English, I do not speak English
