Hey buddy! i litterally had this same issue a week ago on my 2000 GT. all mine turned out to be was the pig tail clip on the back of the wheel hub. you have a little clip connecting 2 wires that lead into your wheel hub; all mine was, was one was cut. all it took was a 16$ clip and 2 butt connectors and about 30 mins. mine was on the front left tire, nice and easy. Hope this helps! there are a million different things it could be! try fuse 13 under the hood as well. and jack your car up and spin each wheel and see if it grinds, if it grinds then it might be a wheel hub
