Same here! I just keep it at 71 and auto. Seldom have a passenger so it's the same both sides. Will use the seat fans when getting in after it's been parked at the mall etc.

Mine seems to blow warm air out the footwell vents and make the car warm. Some days more than others even with roughly same ambient temp.

I too am surprised at the lack of A/C cold air delivery. 2017 C7 Stingray.

The only way my car will cool down and stay cool is to have it set to LO all the time. (sunny and hot or cloudy and hot)
If I turn it up from LO to 17 degrees C (next temp step up), the car immediately blows significantly warmer air that feels damp. My car does have a puddle of water underneath it with the A/C running while cooling.

My previous 2007 C6 would turn the car practically into a freezer set at LO - 15 degrees C. (sunny and hot or cloudy and hot) Both cars had/have the transparent roof. Very doubtful the clear roof has anything to do with it. It's the temp of the air blowing out of the vents.

Has anyone that is experiencing or experienced this issued have had the dealer do a fix on the system, either software or hardware related and be successful?

I usually set mine at 68 to stay comfortable in hot weather. My C7 is my first Corvette so I have no basis for comparison but it seems like the car does generate a lot of heat so it takes a lot of cooling to keep it comfortable.

I finally got them to do an update on mine. It's better than it was but not perfect. Still seems to blow air that's too warm in auto part of the time. Use bi level then to get more flow to my footwell.

I set mine to 73 degrees F and it's plenty comfortable.

My '14 is too cold, and freezes my hands numb if on auto or center vents only. In order for it to be comfortable, air needs to be split between center and floor vents and turned up to above 73º,

speedlink

Not entirely true. When the A/C is functioning properly, the auto setting will choose when to use recirculate or not.

speedlink

My guess is GM, has chosen a smaller and less effective A/C system for the current models. I'm thinking the compressor has less volume and thus less cooling capacity.

Foosh

That's certainly a possibility. Components do change from MY to MY.

Trust me it is what it is I have complained about it in both my 2014 and now my 2016, "performs as designed" is the best I get . I have a laser temp guage and I clocked 110 degrees in the driver footwell !!! Let's face it we have an engine with a car wrapped around it ...

Foosh

Sounds to me like there is a lot of variability between cars. Trust me, "it is what it is" to me means really cold in my '14 (black on black on black) convertible even on a 100º day.

I have had my 16 Z06 on some long road trips in the summer and there is no problem keeping it plenty cold. I also have the transparent top so there is some sun warming going on. With the temp set to 68 and the seat vent set to 2 it is comfortable for me and my daughter usually bumps her temp control up to 71 since I like it cold and she likes it cool.

At night I reset the temp to 70 once the sun is gone; the dash sensor does readjust the system some to offset the impact of heating from the sun but 68 at night can start to feel pretty chilly even for me and I like a colder environment.

Ted P

thought my c7 stingray never got cold because of the transparent roof.
Z06 never gets cold even with solid roof. no comparison to my other cars

NSC5

It is odd that there is so much variance between these vehicles. My 2016 Z06 maintains cold temperature better than my 2014 Cadillac ATS which doesn't have a transparent roof or nearly as much engine compartment heat coming in. The only vehicle I own that cools faster is my GMC diesel pickup which could freeze an Eskimo when set to cold.

I believe modern systems using environmentally friendly refrigerants may be a little pickier about charge level than the old Freon 12 based systems so maybe the factory isn't being careful enough to get the charge level set correctly.

speed4tu

My 16 gets plenty cool. I never worry about what the display says or if it's exactly what the dial says. Put it to where you're comfortable and let it be. If that's 60 then so be it. I leave the recirculation on also as it always helps it to stay much cooler. The "max" of the old days.

Varekai

Getting ready to bring mine in to get looked at, just got her a couple weeks ago. Immediately noticed the AC was not as cold as my mustangs I traded in. I would have the climate control set to 70 in the stang and be very comfortable, I have to have it set to LO and fan on close tot he highest setting to have the same feel in the vette, thought it was maybe a chevy thing with calibration, until I drove my grandmothers GMC Terrain the other day, and on the same settings as the vette it got so cold my hand on the steering wheel near the vent started to get numb. And I'm not just talking about the overall temp in the cabin, the air coming out just simply doesn't get nearly as cold.

vbdenny

You sound like a good candidate for Florida. I have friends that keep it that hot in their cars and drives me crazy. 66 works fine and if I get cold, I just turn on the heated seats.

After experimenting with the A/C controls today, I find that using the auto mode is the problem for the weak A/C in my car. Only on the LO setting it works pretty good, but just turning up a degree in auto mode you can feel the humidity coming out of the vents and the temperature feels significantly warmer than the temperature that is dialed.

Today I put the A/C in manual mode with recirculating button on with air to the vents and the foot wells at the same time and it worked great. Car got cold and stayed cold. Every degree of adjustment made a difference that I could feel and there was no added humidity feeling in the air as the temperature was turned up.

I am going to use manual mode for now and maybe there will a TSB that will come out soon.

phil hunter

I don't use the auto mode, but rather manual mode. Keep the A/C set to 72 and it works just fine. I see no difference between my c7 and my C5 in terms of how cool the car stays.
