Re: Is HVAC burning you up too? Chevy says "nothing wrong"

OK....

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.

With regard to setting the "auto" climate control to 74º and eventually having the cabin climb past 86º, I've noticed no difference whether the Bolt is: Driving in hot weather, driving in cold weather, parked and charging, parked and not charging, daytime, nighttime, rain, shine, or whether it's Thursday. ;)

MEANWHILE, here's a wee update: Of course my car passed the "Air Conditioning System Performance Test" at my dealer a few weeks back. The test consisted of running the system at "the coldest temperature setting" while measuring the temperature of the air produced at the vents, so there was very little surprise (at least in my mind) when my Bolt happily produced cold air in that scenario.

But...my dealer reps (bless their hearts) have continued to follow up with GM and my car is back in the service bay today for a "Vent Temperature Sensor Diagnostic"

...I'll let you all know what happens!

EDIT: I'm in a loaner Malibu. How much does gas cost these days? O_o

What was the follow up to this?

I apologize for not posting an update for quite some time. However, I don't have anything new to add, yet.

My dealer DID convince GM to send a field tech to look at my car, and this behavior did manage to raise both his eyebrows. Still waiting for the next steps, though...

Obviously this is defect from manufacturing. I have exactly same issue. Occasionally it blows hot air when it is supposed to cool down or simply there is no cooling at all. And this usually happens after cooling was working for first few minutes then it is off by itself. If I feel the air with my hand I no longer feel the cool air.

I'd say this is the only beef I have with Bolt.

My 2018 doesn't have an Auto button, so my car's issue isn't quite the same. What I can do is set a desired temperature, then choose to have the AC/heat on (a "guarantee" of that temp that uses more battery) or off (the vents blow whatever air temp is ambient and use less battery). I find that if I am driving more than half an hour at a time, the car will flip back and forth between having the AC/heat on and not, regardless of what I have chosen. Quite frustrating, that I can't either 1) keep the temp that I want (if I chose climate control), or 2) avoid using battery unnecessarily (if I chose not to turn on climate control).

Is anyone else having this issue?
