Well here's a new one. Got a notice in the DIC that the engine is hot and AC is turned off. The temp gauge goes to zero. Now I'm driving in 60 degree temps and not using AC. There's no indication the engine is actually hot - anti-freeze is full, no discernible leaks. Parked the truck at work. Three hours later, message is the same and I drive across town to an eye exam. Two hours later, I leave there to go back across town to my mechanic's shop; a couple of miles into that trip, the code resets, the AC works, and all is well. DIC normal. Engine temp normal. The thrown code indicates a bad thermostat so we replace the thermostat yesterday. Driving back through the countryside from my daughter's house at a leisurely 50-ish mph in mid-50s temperatures this eveing and the code goes off again. Temp gauge to zero, message in DIC. Message can be overridden but comes back when you restart the truck and will probably be on tomorrow when I head to campus.
We'll work on it Thursday but does anyone have an idea what may be going on? Is the safety lockout on the AC an issue? There's nothing to say the new thermostat isn't DOA, but I'd doubt it. Thoughts?
Thanks in advance.
