The lights stopped working on my 89 Club Car. The switch has 3 prongs on it and I'm not sure what the 3rd on is for. Most of the light sockets are corroded and need to be replaced. Is there a source for OEM replacement parts?
If the switch is a lighted switch the third terminal is for the light in the switch.
If you go to the Club Car website they have a dealer locator. There's a good chance there's a dealr near you. Most dealers will also ship you parts. Here's a link to the Club Car dealer locator.
