I haven't had much time to look at it. About the dimmer switch, funny thing is I didn't even have a dimmer switch and the headlights were working.

I have a new dimmer and wire that I haven't put in yet.

I bought a new headlight switch, since it was cheap, and went to put it in but now I can't get the old knob out. I'm pressing the button and pulling but it won't budge.

Thanks for all the advise so far!
