Yes everything worked fine before. If I take 12v and apply it directly to the thermostat it works fine. The wires that supply the 12v to thermostat read 0v. That is what I am trying to chase down is where those wires come from. Talked to a tech at dealer he told me they come from fuse panel and if I can't find the problem to run wire from a 12v source to thermostat for a temp fix.
i was going to use the camper this weekend and canceled the trip due to this problem. 80+ degrees in south florida not fun with 2 kids. Thanks again.
