Why does the Climate control panel on 1988 Chrysler Fifth Avenue not change to cool air?

well. odds are you either have a bad climate control cluster. you can go to any auto wrecker and buy then for about five bucks. I changed my cluster out for a digital climate control out of a 1992 fifth avenue, so I dont have to worry about that. anyway, the other problem you could have, is that you are out of freon. in other words, your air cvonditioning is not working. but if you have freon, then your cluster is bad.
