Yeah I think you're right. When I push on the right side of the button when the lights are up the lights come on for as long as I slightly press it. Seems like the switch isn't making proper contact. Can these be dismantled and made to work properly again? Low mileage car so not like it's worn out.
Thanks. I intend to take it apart and clean it up and put some dialectic grease back on the switch components.Though I haven't tried this, you could use some contact cleaner in the switch and see if that helps. It won't hurt the switch and might just clean it up enough to make it work. Cheap fix if it works.
