My gauge reads completely cold but I got a message saying " A/C off for engine protection", What would likely cause this? Drove a little more and the gauge went to normal and the message went off.

The thermostat is responsible for engine temperature .. IF the thermostat is intermittently stuck in the open position, then the engine will NOT reach proper operating temperature until the thermostat starts working properly .. The temperature gauge on the dash will reflect this and that message will also be displayed accordingly!!!
Why would a failing thermostat cause a message like that, since there is nothing electrical about a thermostat.
