DRKM: My P2 does the exact same thing. It seems to "act up" when there is humidity in the air. My solution is to turn the dial to "off" until I need to hook up. Then it is the "." and "n.c." normal routine. The important thing is that it functions properly when towing. I don't worry about mine anymore. \ken
