I have a new Volt. The first two days I had it, the climate worked fine. This morning I noticed:
1. The car was fully charged, but the EVSE "trouble" light was blinking
2. With the fan on manual, I could control the heating/cooling, but when I put it on Auto, the fan slowed down (maybe stopped) and the car started slowly heating up
3. I pulled to the side of the road, turned the car off-and-on and the situation persisted.
4. At work, I plugged into the EVSE, and all is OK with the climate (at least for now)
I wonder if there is some mode the climate can get into if charging stops unexpectedly. I'll let you know if I see this again. And it's on a Volt, not Bolt.
