Hi Russ77, Good idea but the problem is that even when set to 'cool' the ambient air coming through the vents is warm. I went from hampshire to devon and back this weekend and although the outside temp was reading an average of 17 and when you put your hand outside the air actually felt coldish, it was still warm coming through the vents. I had a mondeo before and when set to cool, that's what you got, unless it really was a proper summers day with high ambient temps (almost forgotten what those are like) :)
