Recently purchased a beaten 2000 GTP that is going to be put back to new/ back to life. Besides tearing down the engine, suspension, etc... the gauges do not light up, the air/ heat does not turn on, and the radio does not display. This is all I know of, right now. Not driving it currently. I saw that the driver info display is working. When I turn on the radio, it plays sound. All interior lights seem to be working. Anyone have this issue before?? Pops says it could be a BCM issue? Also some say it could be the ignition switch? Also, if it is the BCM... where exactly is that located? Thanks for the help!
