First time the commands were working erratically acting weird. Sometimes was heating at full capacity blowing heads off. At other times it was not starting at all. The whole module had to be replaced. Second time if the car stayed in the sun the AC was heating, after starting the engine and cooling started only after achieving greater speeds

I have stripped out and removed the fan motor assembly and dried it out in the airing cupboard in the hope that this may resolve the problem. Unfortunately this did not work. As a bit of an amateur, I need some guidance to test these items to see which needs replacing. I have basic tools and a mutltimeter, but do not really know what to do to test.

If the fan doesn't work, the A/C will be none existent at idle, because the condenser heats up in seconds, so the high pressure in the A/C will rocket upwards, and the system will switch off, the fan should operate at least every 20 seconds when the A/C is on. The underbonnet fuse box is a weak point on C4.s I have changed several, for various wrtvN5. 447 305 199 298 394 364 371 125 472
