Like so many others who have posted this fault, I have tested the hedgehog resister and relay behing the fuse box. Both are o.k. but there is no input to the relay - only to the two blower circuits. I can hear the small temp sensor fan in the climate controller, so am at a loss what to do next. Is there a way of getting the climate controller to give me a fault code so I can get to the fault!!. I have a 1999 Ghia X model.
My local mechanic couldn't help!! any help much appreciated.
