Default HELP! Potential HVAC Issue?

I'm stressing out so hopefully someone can help. I'm a new member but not new to forums (I searched beforehand). I have a 2015 Stingray and the (heat and a/c) only blow from the top and bottom vents; not the "face" vents. From experience in other cars, it sounds like the blend door actuator but I wanted to check with you all. I'm going to try and reset the fuses when I get home but I already called a shop who quoted 15+ hrs in labor as the dash has to come apart. I hope it's something small as 1. this is a fairly new car and 2. I don't want to spend $3K and have my dash torn apart.

Please shed some light!

Strangely I had the same problem and posted about it a few days ago. I tried re-charging coolant, upgrading software, resetting everything. No luck. I'm pretty sure that mine is a blend door too, but thats a moot point as I just pulled the entire A/C system out of my car as I don't really need it.

15 hours does sound a bit excessive for dash out (if thats even what it needs). I've seen a few people post tutorials for dash removal and it is quite involved, but maybe half of that for a professional to do it I would think?

To get the heater box out of the car the dash has to come out. 15 hours including taking the dash out, removing the heater box, fixing what ever is wrong inside the heater box, reinstalling the heater box, reinstalling the dash and probably the effort of draining and reinstalling the coolant if the heater core is pulled out of the car to get to what ever needs to be repaired. How many times do you think a professional does this on a Corvette? Practice makes perfect and they don't get a lot of practice unless they are working in a dealership that sells hundreds of Corvettes.

Okay, so one hour of shop time to reprogram the the HVAC Control Module. You won't find an easier fix.
