I have a 2007 H3 that when I bought it the weather was hot so I had temp set wide open. The first cool morning I cut the temp back and all heat. I can turn temp **** back just one notch off of cold and I have wide open heat. I changed control assemble and programmed it as instructed with no change. Any Ideas?
