I am having problems with the climate control in my 94 318is. It's not the computerized it has the knobs. I can get heat out of the defrost, but the air coming out of the other vents is cold air. Also, the buttons for the a/c, rear defrost, and controling the air from outside/inside don't work. The same time these problems started the radio stopped working as well. I'm not sure if that is just a coincedence or what. I know there are a lot of problems with the computerized climate controls. I was wondering if anyone has had problems like this with the non-computerized climate control. If so, how was it fixed?
