I own a 92 Lexus SC 400. The air and heat have stopped working. The unit will not turn on. My mechanic found that the fuse for the unit was blown, but everytime he replaced the fuse it would blow again. He said there is obviously an eletrical short, and that it might be the control unit causing the problem. He will have to trace the problem next week.
Has anyone else experienced this problem? Is it the control unit? If so, can I buy a used unit? Where from and approx. how much?
