Hi All,
I brought my 2015 Convertible into the dealership since I was having HVAC blower problems- turned out that they needed to replace the HVAC Blower Motor Connector.
While it was there- I asked them if there was a software update for the HVAC system.
Have you guys noticed that with the top down- the car will only blow very lukewarm air for the heater- unless you manually set it at "HIGH" which blows out super hot air. There's really no in-between setting.
The manual heat adjustment works fine when the top is up.....e,g, there's a typical range or low, low-medium, medium, medium-high, high heat.
As soon as the top goes down, you can actually hear and feel a change in the way the air is blowing from the motor.
According to the repair notes- "the HVAC system does not use the interior temp sensors with the top down".
Ok, that makes sense for "Auto" climate control mode. But doesn't make sense when manually adjusting the heat.
The HVAC is my biggest gripe about the C7 convertible.
I also asked the dealership to perform Service Bulletin 17-NA-278 since my top was making a tapping noise while up. https://www.corvetteactioncenter.com...ving-1381.html
I purchased and provided the 6 screws; however, the dealership refused to perform this work under extended warranty.
Another local dealership confirmed that they also wouldn't do this under warranty.
Has anyone done this themselves? It's tough to find where the screws are located even with the diagram.
I was quoted $200-$320 by the dealerships, which is pretty crazy just to swap out 6 screws. Might be better just to take it to an independent shop that repairs convertible tops

So what was the resolution? Is the software fix available? Will it be available?

When I brought the car to the dealer in 2016, the service person said "GM is aware of this problem in convertibles. It's not a high priority for them since it's not related to safety, but they will eventually release a software fix."
Well, fast-forward to 2019, and it sounds like the software fix hasn't been released yet,
Has anyone noticed this on new convertibles (2018 and 2019 models)?
Try leaving the car parked with the top down and engine running- have the HVAC setting around 80 or 85 degrees- put your hand by the vent- and you will notice the air will blow significantly warmer as soon as the top goes up. You can actually hear some sort of noise in the vent as this happens.
This odd glitch isn't that much of a pain during summer since heat isn't needed, but was hoping to get this fixed by fall or winter.

When is this sub section going to be added to the actual C7 section and out of the sticky section? It’s time I think.
It was a sticky, then it wasn't. If I recall it was deemed that there wasn't enough traffic on the thread to warrant a sticky. At least that's the way I understand the switch. One of the admins can answer your question much better than me I'm sure.

It's (location) is fine right here. I skip even looking/reading the heading *pasties after a while anyway.
Fear the C7 convertible: My 2017 Stingray convertible, in Arctic White / Jet Black Tuxedo colors.
Please share your experience with windscreens/windblockers, both factory and aftermarket. I had one on my C6 and it was very worthwhile.
If you have one or have used the C7 version(s) what's your take?
I guess we got a bit spoiled with the windscreen that came with the wife's '15 Infiniti Q60 convertible. The Q60 can be driven with the top down in winter (windows up) and is still comfortable with almost nil buffeting. We can speak at normal levels, use the phone via Bluetooth, and listen to music at reasonable levels with the top down on the Infiniti. When we got the C7 Grand Sport we noticed what seemed like a lot of buffeting; compared to the experience with the Q60. Even with the windows up, the C7 just seemed to have a lot of buffeting. So, we installed a WindRestrictor. It helps a little. But it's nowhere near as effective as the Q60 windscreen. While not scientific, I'd estimate that the WindRestrictor eliminates about 50% - 60% of the buffeting (It's surprisingly small in size considering the price). The Infiniti windscreen eliminates about 85% - 90% of the buffeting. The wife is a physician and needs to be able to answer her phone via Bluetooth while driving, which makes having a "low buffet" interior zone a necessity. The WindRestrictor helps a good amount to that end but compared with the windscreen in the Q60 it's somewhat disappointing considering the price (a lot of Corvette tax).
I see what you did there.
