On the way into town lunchtime I got nearly there and thought "bit cold in here" wacked the heater to 24c and still nothing much. Parked up and turned the engine off, ignition on and couldn't hear the fan or feel any air from the vents =/
Did my bank stuff, got back in to go home and pulling out of the car park the screen mists up then clears, fans back on!
I know this is most likely the "Hedgehog" resistor, but is there a way to be sure of this before I buy a new one? Will INPA pick it up or anyother tests?
