Resolved No dash heat/ac power

2012 RED, Freightliner. Pulled the motor home out of storage yesterday. Engaged both battery disconnect switches, engine fired right up but I had no 12v house power at all. House batteries were new last spring so I was surprised they were completely dead.

Got home and plugged in and 12v house came alive, inverter panel showed absorb charge and shortly after into float charge which to me means the batteries weren’t fully drained. Voltage must have been just low enough not to energize?

Everything on the house side seemed to work except I have no rear view camera monitor and the dash ac/ heat controls are dead. I checked all the 12v fuses in the compartment in front of the driver side wheel and all look good. Is there another set of breakers/relays or fuses elsewhere i should be looking for? The previous owner mentioned when I purchased the motorhome that he lost dash power once and there was a hidden fuse the tech had to change but he didn’t know exactly where it was located. Appreciate any help


Edit, just realized my slides have no power either. Hydraulic slide is fine but my 3 electrics have no power.

Just tried engaging the jumper switch that joins the two battery systems and my dash power came on but shut off again in about 2 seconds. Am I chasing a faulty relay and where would it be located.

Resolved, this was a simple blown fuse. The problem was I couldn’t find it. There is a fuse box under the center console draws that I didn’t know was there. The ignition solenoid fuse was blown which makes sense why my slides would not work since the key must be on to operate. Do not know why the fuse blew but the previous owner stated it happened to him once as well.
