vehicle running – fuel, oil, temp gauges go to zero. Battery gauge stays at 14. Check gauges, battery, security lights come on. Front running light come on. Radio volume diminishes. After anywhere from 2-45 secs gauges come back, lights go out, radio volume higher. This event occurs frequently. Is it a wiring or instrument cluster problem? If instrument cluster bad, what’s causing radio volume and front running lights issues?
