So my headlight switch is now being very finicky and it takes alot of effort to turn off my headlights. I can turn them on just fine but neither of the other buttons will turn it off righ away. I have to mash them for a few minutes then eventually I will get them down. Is there a way I can take these buttons apart and fix them? If not where is a good place to find new ones. Thanks guys
