Thermostat set on auto, turns off when turning on a light

I have a 2001 Dutchmen 31S class C. My over ac works great but lately I've been having an issue. Whether I'm on the generator or plugged in my ac while in auto mode will turn off if u turn a light on....

General thing to check.. When you turn on a 12 volt light and other lights go dim it usaly means a dirty of loose ground connection. Unhook all batterys ect. Go under the rig and unhook, clean and rehook every wire hooked to the frame from the front to the back bumper. Odds are good you will fix the problem.
