Default Normal AC or not?

My previous vette I would keep the air on 71. Just got a new 18 grand sport and I have to keep it on 65 to stay comfortable. Dealer says system is running perfectly and it is putting out 37 degrees at the vent. Is something wrong?

A/C works great on my '18, but I have to put the temp to 72 to get decent heat. Go figure...'06 and '13 worked much better. Output is fine, just have to keep it at 72.

One setting to look at is the “auto” fan speed. It can be set to high/med/low. I don’t remember exactly off the top of my head, but you’ll find it under settings:climate control: fan speed. (Or something close to that).

While this doesn’t change the temp of the air coming out of the vents, it can have a big impact on your comfort level once the desired temp has been reached.

Hope this helps

Same here. 65 in the vette feels like 72 in my other cars with auto climate control.

My 2014 stingray climate control is weak compared to cars I have had in the last 20 years. I turn up the fan speed and operate the seat fan during most of the year in the Sacramento area. The left vent is pretty weak all the time. I also operate mostly with only the upper vents on to get more air flow. I usually need to set the temp to 69, but that really hasn't anything to do with the actual temp. Set at 69 feels like about 76 in the car.

I have a 2016. It came with see thru top. A/C probably cooled but it felt warm on sunny days. I switched to CF top, A/C works really good every day. It is a daily driver. Outside temps been mid 90's in Houston in traffic?

I thought mine felt weak also; new '18 all black. It's colder when driving / RPM's are up - maybe because of spinning the compressor faster? Anyway, I set the dial to LO, turn on the seat coolers, and it's good during the 90+ degree days of full sun. Definitely doesn't blow ice cubes like my Duramax tho..

Same here (2017). AC is very weak...nothing to do with fan speed.

Similar discussion here =>. https://www.corvetteforum.com/forums...very-cold.html

The Corvette is a dedicated sports car that is optimized for speed over comfort and its design/packaging does generate A LOT of heat versus an SUV/Truck, so I would expect that an SUV/Truck would be able to provider cooler air than a Corvette. My wife has commented that her foot well area gets very warm/hot when driving the Corvette. We can't have everything right?

My AC works fine. I have to keep it on 71, even on hot days.

Don’t expect a Corvette to cool your butt as effectively as a SUV. A/C works appropriately, but it definitely struggles to keep your butt cool especially when you’re sitting only inches from the exhaust. There isn’t much to insulate you from 4 catalytic converters and a dual exhaust.
