    Default Ac off due to high engine temperature

    I got this message a few minutes after the gas generator turned on. Has any body else had this message.
    The volt is in the shop. They said there replacing the thermostat heater. I never heard of that. I heard of thermostats but not thermostat heaters. Normally when the car is stopped at a red light or parking, the engine turns off. After I got this message the engine keeps running even when stopped. Also after recharging the battery, it stayed gas mode instead of switching back to electric mode.

    One search I did stated this. Not sure if related but I thought it was interesting.

    there's a heater in the thermostat housing that tricks the thermostat into opening up more under heavy load conditions.

    Well technically you cannot replace the thermostat heater, separate from the stat and housing. It's all one part.But there should have been DTCs if it got to the point of bringing up the warning message. Did Onstar give you those? P00B7 perhaps?
    Hopefully they get you back in your Volt soon.

    The more I learn about the Volt, the more I realize how far cars have advanced in general since my teen tinkering day. It seems that almost every month another mysterious Volt component comes to light.

    I found this the other day. Some sort of fuze I think.

    Yup. That's the time management Fuze. If it ever starts glowing, make sure you have your towel with you, and hope it isn't a Thursday.
