Ok, As there is a lack of reply I have done some more digging, turned out that the 30amp A/C mega fuse was missing from inside the engine bay, having purchased a new one I found the old one in the car! Having put the fuse back in the fans are now working but only at one speed and not conditional to the key being in the ignition or not, ie the fans run all the time, the temperature and directional dials are now working correctly but the fan does nothing but run all the time even if the car is not in use, hence the fuse being removed!!! Air conditioning also did not appear to do anything, but thats probably another story. So do I now try and get the resistor out? Even so why are the fans running without the key in the ignition...? Any help...?
