It seems as though my climate control module may be failing. I have to wiggle the switch all over the place before it comes on. Ususally it will stay on if I can get it to come on. Sometimes I can get it working in speed 1 and sometimes in other speeds. I think this is what started to happen before I replaced the CCM about 3-4 years ago. I just replaced the resistor so all the speeds work fine. Do you think this could just be a contact problem with the fan switch? How hard is it to clean the switch?
