  1. Problems, Driver Warnings or DTCs - Gen 1 Volt
    I've been fighting a heat issue with my 2015 Volt. The heat always works when I have it in "HOLD" driving mode. But when I'm in normal EV mode, sometimes the heat works but most of the time it doesn't. Living in Michigan, this is going to be a huge problem this winter. When I turn the heater...
  2. Problems, Driver Warnings or DTCs - Gen 1 Volt
    yesterday my 2012 volt when I turned on the AC only blew air from the wind shield defrost. Today the same, I selected all different modes dash floor, turned on the air recirculation etc. I only got a faint wisp of air through the dash vent, while blowing full steam through the defrost. This is...
  3. Problems, Driver Warnings or DTCs - Gen 2 Volt
    Question, I remote started my Volt and now when I get in, the Auto Air Conditioner mode does not work. I can manually set and it cools good, but the auto no longer works. After starting and stopping a couple of times, I did see a message popup one time after I started that said "Climate...
  4. Generation 1 Chevy Volt (2011-2015)
    Gen 1 Ampera/Volt 2015/32k miles When I press the power button, a loud hum starts about 3 seconds after. It stops if I either set the cabin heater Blower fan to 'OFF' or reduce the temperature to 'LOW'. Local Ampera (it's a UK car) Service agent changed the cabin blower motor fan (under the...
  5. Use, Care & Maintenance - Gen 1 Chevy Volt
    I've owned a 2012 Volt for a few years, and it's starting to get up there in milage (purchased it with only 13,000 miles on it). I noticed today that in the comfort mode for AC, the selected temperature wasn't there, but it just showed LOW. I have no idea what that means, and can't find anything...
  6. Problems, Driver Warnings or DTCs - Gen 1 Volt
    Sorry if this has been covered, couldn't find anything similar. In the last week I just started getting a humming sound and a vibration when I engage the climate system. As soon as I turn it on you can hear/feel it. The heat works it's just louder than normal. Seems to be coming from the front...
  7. Generation 2 Chevy Volt (2016-2020)
    I have driven my Volt since early Summer, and so far I am happy with it. I am using it mostly for short distances, and my mileage stands at around 250 mpg :-) But I live in Denver, and the cold season is upon us. We just had a bit of snow ... I had a bit of a problem with keeping the windows...
  8. Problems, Driver Warnings or DTCs - Gen 1 Volt
    I searched the forums and couldn't find anyone that has had this same problem. We have two Volts, both 2013's. Mine has 66k miles on it, Wife's has 42k, and it's 12 month CPO warranty was up in May. :mad: Tonight on our way to dinner, the climate control was set to comfort, and 70 degrees...
  9. Problems, Driver Warnings or DTCs - Gen 1 Volt
    Hi Everyone, This is my first post on this forum. I purchased a used 2015 Volt, with about 14k miles, about six weeks ago. I've been driving it daily. It has been hot here in St. Louis, in the mid-90's. I park the car in the shade while at work. A few days back, with plenty of charge, I found...
  10. Generation 2 Chevy Volt (2016-2020)
    Is there a way to control whether the car is heating or cooling? When the temperature is hovering around "nice" it's hard to stop it from wasting energy. I don't want to turn it off completely, because it might get too hot/cold, the windows fog up, and lack of air circulation makes it...
  11. Newcomers, Owner Stories, FAQs
    I am trying to come up to speed on my new (to me) 2013 Volt. My wife suffers during the winter with cold feet. Of course I purchased the car during the end of the summer when it was impossible to test the heater under real conditions. Now that the first cold snap has hit the Minnesota river...

    Have a new problem with the climate control, i.e. it's not working. Any suggestions for a do-it-yourself fix? Also get a message "Charge could not be completed" when using the 120V charger.
  13. Mechanical Systems - Chevy Volt
    Hi All, In Australia where winters are fairly dry and most areas we DO NOT suffer from the the need to remove cabin condensation / fog, is there any way to override electronically, electrically or mechanically to stop A/C operation while heating. It is absolutely crazy that in Eco / Max...
  14. Problems, Driver Warnings or DTCs - Gen 1 Volt
    In June, I traded in my 2012 Volt for a 2014. I only recently needed to use the heat and have noticed the following strange behavior. I normally keep the temp set at 71-72 degrees. I may switch back and forth between "Comfort" and "Econ" but I always leave it on "Auto". When it started to...

    Hi everyone. I've noticed that when I am in Fan Only mode that the AC will come on, even when the interior temperature and outside temperature are equal. What do I do to use only outside air? I've tried everything and it will still cycle back on and go from 3% usage to 22% usage or more. ECO...
  16. Problems, Driver Warnings or DTCs - Gen 1 Volt
    Hi, this is my first post and the first problem I've had with my 2014 Volt since buying it in November, 2013. I live in Miami, FL and therefore it is really hot outside from May - October. Since we are now in the hot season, I've started to use the remote-start feature to cool the interior of...
  17. Problems, Driver Warnings or DTCs - Gen 1 Volt
    Normally, I drive with the climate control in "Fan only" and the selector set to "windshield and feet", with the fan on the lowest setting, and fresh air coming in to the cabin. I stay warm enough and the windshield stays clear of mist - mostly. On days when it's <27F or so, the ICE comes on to...

    Climate control question moved to sub-forum Problems/Issues where it belonged (Moved this to Problems/Issues, Driver Warnings or DTCs -Chevy Volt where it belonged. Sorry)

    I took this shot the other day, and it was quite hot outside (102F). As you can see, the AC system is 'Off', the Fan is in 'Fan Only Mode'... but, there was plenty of cold air coming from the vents! I decided to go ahead and close the windows and enjoy the cool air. Eventually, the...
  20. Mechanical Systems - Chevy Volt
    I've had this issue every once in a while, the photo attached is from over a month ago. However, today was a very damp, drizzling rainy day and around 40F out when I was driving my Volt and I got the same situation again, twice. I was in EV/CD Mode and had set my Climate to run on Fan Only...
