The A/C works for a short wile the shuts off. When you check the thermostat is say 32 deg. when the temp in the rig is 74 or higher. The other 2 A/C work fine. I have move the thermostats around and no change.

Sounds like your experiencing a communication problem. Pull the thermostat the comm cord looks like a telephone wire look for corrosion ( green in the connection) now go to the roof remove the ac shroud. I believe that the communications cord is in the mixing box. Clean both ends and apply dielectric grease to prevent moisture and further corrosion..
