I'm having some electrical issues with my car. I'm putting in the instrument cluster and my lights on the cluster will not come on when the headlights come on. The wiper and turn signals work as does the gas gauge indicator. Any thoughts on what may be the problem? I'm considering changing the voltage regulator on the back of the panel. Any way to check this to see if its working? No fuses blown and there is power to the harness plug. Any help from the experts here would be appreciated.
