Motorhome Htg/Ac Problem
 

I just bought this motorhome last fall, 2001 Monaco, when I got it out of storage my furnace/ac sysytem will not work, it did last fall. It is one of those comfort control center, 5 button duo therm themostat, with the different zones and all of that. I took it to the local RV center but it has them stumped. They found a broken wire in the phone cable style cable that runs from the front ac to the tstat, put another cable on and still nothing. Called Monaco and they told tehm a couple of things to try and still nothing. All fuses appear to be good as there is power where there needs to be. Does anybody have any suggestions?
