Int. Prostar with no power to bunk heater panel

I have a 2015 international prostar elite, here's my issue: I cannot operate the bunk heater panel. The lights come on but i cannot get the blower to work. Both the no idle heat and ac do not turn on. They were working great then they stopped. I checked the fuses in the front passenger side and the fuses under the bunk. They are all good. I've reset my inverter. That didn't help. Where else could i look for fuses or relays? I believe that is my problem. Do i have to remove the passenger side outer vent door to get better access or just look from bunk area. Any and all help is appreciated. Thank you in advance.
