Hello, some gauges (fuel, voltage, oil pressure and temperature) will zero out but the speedometer and tachometer still work. The battery, ABS, brake and sometimes security lights come on when this happens. Radio, door locks and the air conditioner don’t work but the blower does. I’ve checked fuses and grounds. I’ve replaced the ignition switch and discovered that when the issue occurs sometimes moving the tilt on steering wheel up and down hard it fixes for the short term (discovered out of frustration).
