Thanks for the suggestion. The guy who is recovering my seats is able to install a heating and cooling system. I should have the car back in about 2 weeks, so I can let you know how well it works.
What they do is carve out a square in the seat foam and place a fan like you would see in a PC case. They send the leather out to be perforated, and there is some special foam and other parts involved to allow air flow. The system they use is from
www.seatcomfort.com. Their web site is horrible, but you'll at least have some contact info.
I don't know how much the parts are, but they are charging $750 to install it.
They are also re-shaping the seat so I won't need to use an ugly lumbar support pillow when I drive.
In addition to the seats, they will be covering the doors, lower dash, center console, back wall, and roll hoops in Saddle and black leather.
