I have a 2004 S4 which I am having a few issues with. Latest is the radiator and air con fan not working. I assumed that if I put the climate control to low that the air con fan would come on but it doesn't... I have had the system gassed a d cleared a couple of fault codes but the air con still is not cold and the fan does not come on. In addition I have had to drain the coolant as I replaced some o rings on the air con ppm and part of the process was to get the radiator fan to come on. Diagnostics showed the car got to 102 degrees but still no fan. I have checked the fuse and that's fine so wondering what next to check. Vcds is not reporting faults with the system anymore but still no fans or cold air from the air con. Econ light is off and the internal fan goes to full.
thanks for any suggestions
