Seems like you lost vacuum to the heater-A/C controls
Check all the small vacuum tubing under the front hatch and vacuum canister and under the dash between a/c controls and the duct work and blower
Your RV might use engine vacuum, or it might have a small vacuum pump, really small like 4 inches square or smaller , 12v and under the dash
