Ventilated seats

As I'm out driving my new C7 (LT2) and trying/checking its numerous features, I decided to try the ventilated seats. I've never owned a car with this feature. Both my CTS and SRX have the heated but not ventilated seats. Shortly after engaging the ventilated seat my butt got noticeably cooler. This prompted me to wonder how this feature works. It seems to actually cool rather than just circulate air thru the seats. How does this work? Does it have cooling coils or some how push cold air conditioned air thru the seats?

you cant change original title - just a mod can...the seat cooling is not cooling per se, it is just a fan blowing thru the seat - whatever temp is in the car

Yes the OP can change it I have done it before

I have had several cars with heated/cooled seats. The cool setting is just forced air but no actual cooling.

More important is if the air flows both from the seat bottom and the back of the seat. Usually the seat back is not ventilated which is unfortunate because that is the area that cooling makes the most difference.

To the OP, did your seat back also generate cool air?

To answer your question, they are fans that blow air into the seat. They do not decrease the temperature, they just blow cabin air!
As far a spelling errors, I follow the General Andrew Jackson belief, “It is a damn poor mind indeed which can't think of at least two ways to spell any word.”

I used it and it felt good even though it is just circulated air.

This is helpful to hear this discussion. I have had cooled seats before and using the one in my Ray seemed to make no difference I could sense.

I'll have to take it in to have it checked out.

Anyone else have this problem?

Unless the GM seats work differently than others I believe they actually PULL air through the seat rather than blow air onto you. The clothes you are wearing and the amount of perspiration on your body will be the largest contributors to what you feel. If you are wearing light clothing and are sweating, even a little, the cooling effect is almost immediate. If you are wearing jeans and multiple shirt layers and not perspiring you won't feel anything. Ventilated seats uses evaporative cooling, if you aren't perspiring and/or the air cannot circulate past your skin no temperature change will happen so it will seem like it's not working.

The comment about evaporative cooling is spot on- here in the desert a common complaint of the fellow Cadillac XTS owners was that the 'cooling' seats did not function at all. It wasn't until we had some higher humidity days that the effect could be felt. Having said that, the Stingray's seats do a much better job of moving the air than my XTS seats and even with uber low humidity you can feel the 'coolness' when you activate them. Bottom line is that it is just air movement, not a dedicated chilled air movement through the seats, but it does help compared to no seat ventilation. :cool:

For C 7 owners : do the seat backs cool too or just the seat bottoms?

Both seat backs and seat bottoms have fans, but only in the 2LT and 3 LT interiors. No fans for the 1LT interior, neither in seat bottoms, nor in seat backs, nor are 1LT seats heated.

This makes a lot of sense. I'll test my seats in shorts.

Thanks. Good to know. My present cars with cooled seats only circulate air on the bottom. Actually makes you feel as if you have wet your pants when you use it in the summer. Unfortunately provides no ventilation for your back which always seem to be the area that you sweat the most.
