[Shotimes] MY 89 Headlights randomly dont work. MULTIFUNCTION SWITCH? HELP PLEASE

[Frank Costa]

I was driving my car one night and then all of a sudden my headlights dont work anymore, when i go to high beam it highbeams but it doesnt stay in "high beam" mode and the headlights dont work. all my other lights work, what could be the problem? anything similar? maybe the multifunction switch? i checked in the fuse box and and no fuse was blown, unless there is a second fuse i dont know about.
