Ok read lots about the resistor. Its not that because the resistor pack is integral to the motor, being sited on the heat sink. Found that by accident!! However no power to the motor at all so need a circuit diagram of the aircon/blower and which fuse and relay makes it all go. Of course this car is not mine, its my daughter's and Haynes manuals don't include the cc model, and trying to trace the wiring in this 2004 model is a nightmare to say the least. What ever happened to plugs, points, alternator and thats it!!!! So can anybody advise me on where I can get the diagrams from please.
