Another electrical problem on my '06 Expedition, whole house Thermostat. Did have air and heat Saturday morning here in Silverton, CO - - a little later, no. There was no 12VDC at the thermostat. Over the course of Saturday and Sunday checked a number of things. AC power to both roof units from breakers in the Intellitec breaker panel, 12VDC out on all fused circuits (fuse box over the Intellitec panel at foot of bed). The upper left 12VDC fuse position is indicated "thermostat" - - can you confirm that that is where the thermostat should get its 12VDC? I had 12V at the fuse but nothing at the "12V in" at the thermostat. I pulled the fuse, and (until I find the problem) I hooked the thermostat "12VDC input" wire to a nearby 12V plug. System operates normal. Next question - - can you refer me to a shop drawing or something that tells me the routing of this 12V wire from under the bed to behind the thermostat at the multifunction panel high on right over the windshield, so that I may intelligently look for the fault?

I DO have 12VDC out of all fuses in that panel, and while a schematic may let me confirm that the upper left fuse is to provide power to the thermostat, it wouldn't be as handy as a diagram showing the routing of that 12VDC wire to the thermostat
