Furnace and Air conditioner trouble

Last fall we were camping in a Corp park and had the Air conditioner on in the living room. We have 2 airs and two furnace in our 35 ft 1998 Pace Arrow. During the night I was awaken with rhe furnace motor kicking on. I turned both units off but heard a loud relay clicking from behind the breaker panel. The next day I unplugged the front furnace motor so that we could continue using the Air. When I got home I checked the contacts behind the Climate control panel and made sure all connections were tight and didn't have any more problems until this month. We were away from the rig and when we returned the front furnace motor was running. Nothing was turned on no heat or air. Once again I unplugged the front furnace and we used the rear furnace for heat when we needed it. Could the Intellitec Climate control be causing this problem. We have been having the loud relay noise often even when noting is in use. I've located the Intellitec main control board behind the breaker panel and an Intellitec Transfer Relay Delay box in the same location. I think the relay noise is coming from this box. Does anyone have an Idea on what is causing my problem? I guess it could be a short in the wiring too
