I have a 1993 model 9000cs with air conditioning but not climate control. With the airconditioning switched off, & the heating dial turned to the coldest position (that is; fresh unheated air), I am still getting warmish air coming in. The dial is definitely turned anticlockwise as far as it can go. Even on the coldest day, warm air is coming through the vents. While this is not such a problem in cold weather (when I would have heating on anyway), it is a real problem on warmer days. What it means is that I end up having to have the airconditioning on on a day when I really shouldn't need it. I assume that the heating comes from the hot radiator water, & suspect that even on the coldest position, something is still open allowing some warm air to leak through. Can anyone offer an opinion as to why I am getting warm air & how to go about finding & fixing the problem. thanks in advance Bryan
