tram, that's a good suggestion. In fact, the ignition switch was replaced before I bought the car. The only thing that makes me question that is the 'thump' I hear when I rotate the blue/red temp dial to the 'coldest' position. The key is in the 'run' position when I hear this. Now, I have to plead complete ignorance here. I can barely understand how the push buttons work. No manual and all.
