I disconnected mine. Sure it gets alittle hot and uncomfortable, but I didnt mind it at all. My 200SX has A/C. But in the summer time I only used it when my girlfriend and her daughter were in the car with me. I guess im just accustomed to opening my windows and letting the air cool me off. Besides, summers in L.A. are not that bad. Its only hot for a couple of months. The rest of the time the weathers great. If you had moved to Pomona or Santa Clarita, then I would have said to connect it. It gets hot as hell in the valleys.
