I have a work truck, 2002 Ram 1500 with a problem with climate control. The fan only runs on the high position and nothing else. Compressor is OK, replaced the cond. fan assembly, so would like input on if the problem is in the climate control assembly in the dash or somewhere else. I hate ordering parts and they are not the problem. I have dissassembled the unit, and see nothing apparent that would cause a problem, cleaned and lubed the contact points on the switch, runs only on the high fan speed. Any thoughts on what to do next?
