Hi everyone,

Been feeling warm/hot temperature in the driver side foot well area since I got the C7 about 3 months ago. Regardless of the outside temperature, or if I have the air conditioning set to freezing, I always felt that once the car is up to operating temp (220), its always warm or hot in the foot well area...

It could be 70 degrees outside, with the air conditioning set to 65 degrees, it will still feel toasty on my lower legs and foot.

Figured out it was radiating hot air from the center column to the right of the gas pedal.

Anyone else have this issue? I sincerely hope its not normal, and that it can be addressed by dealer. I hate it because I would have sweaty feet while my entire body feels cold...

Take it to your dealer it is not normal. There a lot of different things that it could be. Computer related, flapper valve, faulty controller, etc.

Rayw indicated that the hot air is radiating from the (steering?) column next to the gas peddle. Generally there is a air vent in that area that heats/cools the cavity by your feet. I think this where the warm air is coming from. If so it is a heating malfunction. If the insulation was not working the center console would be warm. Rayw please clarify the origin of the heat. Thanks

He said it was radiating heat from the right of the gas pedal. I was thinking he may be missing some Aerogel in that area (or maybe it is present, but damaged). I was also thinking that the Aerogel is present and working properly in other areas, and that is why only one area got hot.

Of course, this is just a guess on my part trying to brainstorm possibilities in hopes something helpful may come out of it.

I'm sorry, I was mistaken... After a drive tonight, I found out that the hot air was coming out of two tiny vents in the foot well area, one on the right side, one towards the middle.

When I set the A/C to auto (or manually divided it between foot and face), it will vent hot air thru both of these tiny vents onto my feet, while getting cold air into my face. When I have the setting on manually with air directed only to the foot area, it will vent cold air to the feet.

I'm guessing its a HVAC issue and hoping that it can be addressed with a reflash at the dealership.

Okay, I was definitely on the wrong track with that one.

I hope all goes well with the HVAC firmware flash. Let us know how it goes. Good luck!

Hi Sriegle,

Thank you for providing us with this update. I am happy to hear this concern has been resolved for you! Please let us know if you need assistance in the future at any time.

Went to dealer with same heat in the foot well and they called tech at Chevy. Reprogrammed all my heat sensors and it's like a new car.

My C7 has been at the dealer for 2 days with this exact problem, yet the dealer is still trying to confirm that this is actually a problem, and not just normal operation. Does anyone have a TSB or other reference number for this fix that I can pass to the dealer?

So.... I'm not crazy! I can move the temp from 70 with AC on and it blows cold to 72 and it's super hot. I've been wondering why this system is so weird to control. If it's 75 outside and I have the top off I run the AC on feet just so I don't roast my legs. Sounds like its time for a trip to the dealer.

Sriegle, any idea what the tech told your dealer to do? My dealer just kept me C7 for two days, told me that they reprogrammed the ECU, yet the problem still exist.

I have a c3, which means that unless it's really cold out, I have hot feet! The engine just makes that area hot!

I haven't noticed the c7 doing this, but I've not driven her much with it really warm out and the a/c on. We shall see.

They reprogrammed the ECU, but also mentioned recalibrating the various temperature sensors in the car. He had made a call to chevrolet and was first told nothing to do, but then discussed it further and was advised to proceed with recall ration of sensors. I will look at paperwork if I still have it. At work right now. My 24 hr shift ends in 4 hours and 23 min, but who's counting?

I can't find paperwork. It's possible my son has it in his car, but he is at college. If I find it, after finals and he comes home, I will PM u.
