earth wire to it. Hope someone can help .Many thanks Gerry (NZ)
It is earthed through the dash panel. If you think your ground is bad, you could you could always run a separate ground wire if desired. Might help to check the switch itself and make sure the contacts are doing their job.
A VOM would prove that you have power and ground to the light bulb socket and which or both is/are faulty.
