2000 Chevrolet Impala Heat/vent/ac Runs On High With The Engine Off

I have a 2000 Chevy Impala w/162,000 miles. Recently the “Service Traction Control System” and “ABS” lights have come on. Traction control does not work, neither do the anti-lock brakes. Also, when I turned the defroster on it later would not turn off, even with the engine off and the keys taken out of the ignition. It continues to run on high, and I am unable to switch to A/C. I went to the dealer today and they pulled a fuse out of the passenger side dashboard area and this temporarily fixed the problem. Does any one know what this problem may be?? Thanks all.
