If it's too hot, I open the wing vent more. If that's not enough I open the kick panel vent, which I rarely do. I don't have a working radio, just listen to the car as I cruise along. A/C is nice but I've never felt the need for it in my old cars, my Polara doesn't even have any of the heater vacuum lines hooked up, I can only adjust the temp!I take it, you guys that don't like AC really like to sweat and that wonderful wind noise going down the Interstate at 75 MPH!
