My Taurus has no speedometer, tachometer, radio, climate control, reverse lights and the heater runs on defrost continuously. This happened all at once. When the key is in Ac position I have wipers and radio. Lights in the center part (radio and climate control) work sometimes when car is in park. I replaced the ignition switch - no change. Looked at fuses and swapped relay positions and no change. Any help would be appreciated. Thanks, Mike
