carlos3 Posted July 27, 2007 Report Share Posted July 27, 2007 Hi I have a audi a3 1.8 T 1999 model. The engine fan is continuously pulsing on and off and my air con is no longer cold. What do you think is the problem? Regards, Carl Link to comment Share on other sites More sharing options...
carlos3 Posted July 27, 2007 Author Report Share Posted July 27, 2007 Had a quick look into this. It could be a blown resistor or a bad wire. At worst it could need new fans and control unit. Any experts in this field out there? Labour costs will be high if I take it too Audi, better if it is nothing too complicated. Link to comment Share on other sites More sharing options...
johnny11 Posted July 29, 2007 Report Share Posted July 29, 2007 my RS6 was doing a simular thing today, you could not turn off the econ when the aircon was on, it was not getting cold, and if you turned it off the compressor still ran all the time Link to comment Share on other sites More sharing options...
