I've had this 96 Suburban Geneva GTS for a few years and all of a sudden, none of the extra stuff works. Such as the headed and cooled cup holders, tv, vcr, rear radio, and sunroof. But all of the regular suburban electrical stuff works such as the powered seats, locks, windows, etc. Its just all the extra electrical stuff doesn't. I've looked at the fuse panel on the side of the dash and no blown fuses as well as the relay panel under the hood and still nothing blown or bad. I've ran out of ideas and need some help!
