Hi forum members

I'm close to ordering the 2015 and just read this article post in car and driver this month pointing out that after the car runs for a while in stop and go traffic the footwells blow out hot air from the engine

I haven't seen a post on this by anyone ?

Has anyone noticed this. I live in florida and sure don't want to be any hotter.

Thanks for any feedback

It's been brought up here before.

I have experienced this on long trips. I found it helpful to keep the AC at 70

Wouldn't you consider that a fundamental design flaw relative to insulation ?

Perhaps but not much can be done at this point. This is my first Vette but I have heard prior versions had this issue as well.

Thanks for the reply

I don't actually think that the heat is coming from the engine/tunnel. I believe it is the way the AC system routes air when it is on "Auto". At times it is blowing perfectly cold air at face and body levels but seems to be blowing warmer air out of the lower ducts. You can manually override this and it eliminates the issue. As for the car running hot, I have never experienced the engine temperature to get any where near the hot range even here in the desert when we were above 110 degrees external temperature. The only time I have seen the engine temperature rise (and even then it was still well within the normal range) was after a very energetic run.

Thanks jsvette

I ink that is the exact issue

Can you explain how you can manually override this ?

I am hesitate to order because of this but would really appreciate your guidance on setting me straight

If the AC is on recycle and the vents are not set to blow to the footwells how can you avoid this flow of warm air at the footwells ?

Thanks again

To override take the AC off of Auto, set your temp where you want it, set the distribution where you want it, and set it to recirc. Should solve the problem.

 

[proowner7]

Ok
Thanks

Some of the early issues were solved by an ecm re-flash.http://www.stingrayforums.com/forum/stingray-corvette-tsb-recalls/3778-hvac-temperature-fluctuations.html

My dealer's response was that there is button to fix this. He pointed out the button that directs the air to your feet... When set to auto it keeps from the waist up at my desired temp, but feet get warm. This also means that when I turn on the seat fan I get warmer air blown up my rear. Not a big fan of that asspect.

Ask him to check / update the climate control software. I believe they changed the programming to not open the footwell vents in the current release. I know mine was doing exactly as you describe but after having the car updated a couple weeks ago it no longer seems to do it.

When you put it that way I have to agree! I think the re-flash will correct the problem.

I had the car re flashed and it is still warm in the foot well. I found that the heat is not coming from the air ports under the dash. It is coming from from an area to the left of the steering column.

Ok, then your issue wasn't mine. Mine was coming from the heater vent.

Does your AC system otherwise seem to be operating normally?

 

[mybluecorvette]

Chip,
The Air system is over reactive to temperature. If I turn the temp knob to try to match out side temp it still blows air in in high setting in the auto setting. I have had it to two dealers and they can not figure it out. I still love the car. I wish I lived closer to mc mulkin. They would probably have better mechanics. I was in nh last week for a business trip with out the vett and I needed the panel for the grill. I spoke to Paul in parts and he overnighted me the parts. Super help, service and followup to make sure I got the part.

Joe; Did you ask if it (the car) is saving any fault codes. That sure sounds like that is a programming / miscommunication issue, or just a bad ecm. Good luck!

 

[proowner7]

Isn't this a build and insulation issue because i don't think it's coming from the footwell AC vents but gaps in the footwell area that allow the hot air to come from the engine in the cabin
