I traved from Augusta, GA to Montgomery, AL and back last week. No problems over the weekend or this morning. But when I went home at lunch and got back in the car and tried to turn on my A/C, it would not turn on.. I also noticed that the Temp Gauge on the dashboard no longer registers a temperature. I have read that it is the thermostat more than likely. The things I have read says that it sticks once in a while. I had a couple questions:

1. Is this repair covered under my warranty?
2. Is it possible that it will "unstick" itself and be ok?

Any assistance would be greatly appreciated!

Your A/C not working could be the PC reading a high temp from a defective thermocouple. The warrenty, ? dono,
You better take it in and have them (dealer or friendly shop) check the code.

Welcome to the club, let us know what's up!

Would that also cause the temperature gauge on the dashboard to not register a temperature.. I know it has been cooler here today but I don't think the engine would run at 0 degrees.. hahaha

I'm not sure about this but my gut says that your cars PC has a up or low scale burn-out meaning if the thermocouple breaks the PC will read fullscale temperture (about 280degrees F) or low scale (0 degrees F.) This will affect the way your cars operates. The A/C not working could be one of the safety precautions.

Off to the dealer I go hopefully tomorrow or the next day.. YAY!!! Thanks for the information!

Just want to update you guys! I took my car to the dealership this morning and dropped it off. They said it was the Thermostat that was causing the issues. It was sticking open.. Total cost including the $100.00 Diagnostic fee = $318.67.. Better than I thought it was going to be seeing that I took it to the dealership. I called a few local auto shops and suprisingly they told me to take it to the dealership. In case anyone else has this problem I hope this information helps and this site has already been worth the time and effort, thanks everyone!

Thanks for posting the results.

I may just be crazy but something about the thermostat being the problem sounds fishy to me, I will be honest, im not a professional mechanic and I dont know alot about the newer computerized cars, but If I remember right if a thermostat is stuck open then that means the water in the engine is just flowing freely thru the system without anything stopping it to let it get up to a certain temperature. one would think this would cause the water not to heat up, but it still gets warm, try your heater, if the water in the engine wasnt warm then it would not be hot. this being said if the water is warm then the temp guage would be reading something at least. not 0 degrees and throwing a code up. the only thing that would make me think the thermostat was the problem would be if there was some sensor on the thermostat itself telling the computer it is stuck open.

UPDATE: well, apparently i was crazy, it was the thermostat in my g6 as well. dont exactly understand it but it fixed the problem as well as when i pulled the old thermostat the seal around it was pulled away at one part , would have let all kinds of water pass thru it

I have experienced multiple thermostat failures due to the internal rubber seal. It shifts and has locked the thermostat closed, causing my engine to overheat, and just again stuck open by twisted seal causing full temperature to NOT be reached. Which disallows AC usage and shows no reading on internal temperature guage. New thermostat is the same design.

Has anyone talked to Chevrolet about this?
