Hi Folks, we have a 2012 Sightseer and I think the thermostat is malfunctioning? It does turn on the furnace or A/C but doesn't work automatically when controlling temperature. Problem is while searching the net this thermostat seems to be discontinued as no information is available. Has anyone else had to change out the thermostat and if so what was it replaced with. The controls on this one has switching for A/C/gas furnace/electric furnace with additional switching for auto or on (for the fan)...
