Default A/C & Heating

It seems that no matter how cool outside it is, my heating (no a/c on) blows warm to hot air out with the temp set on 61 or 62. Has anyone else had this bloody problem and if so, has Chevy fixed it????? Received my 14 in October 2013 and has been in the shop three times for a "flash" and other BS.

My 2015 does exactly the same thing. Several others have reported the same, as well. Don't know of any remedy at this point other than to use the A/C when necessary or turn the ventilation fan off entirely.

Supposedly there is a fix, bring it to the dealer tell then what's going on and let them reflash it. Don't take my word for it, just going by what I've heard.

Don wins the prize. My dealer located an HVAC-specific update that applied to my car (an early 2015 model). It fixed the problem; the car now blows cool outside air instead of warm air, as before.

GM thought that the **** poor HVAC design was such a good idea on the C6's that they carried it over into the C7.

I don't care what the temp setting is on the unit, if I feel cold I turn it higher, I don't really care if I have to turn it up then turn it back to get the car at the temp I want it.

I never saw a climate control unit work better than a standard heat system in cars, they always fell behind in performance compared to the manual systems.

I had a 1990 Sedan deVille and a 1997 Buick La Sabre Limited and both of their automatic climate control systems were seamless in operation. Exceptional compared to the Vette.

I only wish that the Corvette's climate control system was half as good as those two cars.

My 2014 Z51 had the flash and did not fix the issue. Also if you set the temp to 60 which is low the A/C comes on and there is no way to shut it off.
