2016 Coachman Pursuit RV AC problems

Been fighting this for a while and throwing parts at it but cannot figure this **** out. I cannot get the thermostats to turn on. I get good 12v power at the ac unit, I thought for sure it was the wiring in the walls so I hooked up the thermostat right at the wiring junction and still nothing I’ve tried a new thermostat and that doesn’t do anything either. WTF. Is anyone familiar with these and had a similar problem? I’ve checked all the fuses and breakers everywhere
