headlight not working. on 1992 Dodge W150

both my headlights stopped working at the same time. i found this to be wierd. the hi-beams would work, but i had to hold the lever for it the entire time. all other lights work. i replaced headlamps and still having problem. i looked at my fuses and they are fine. has to be the wireing right?

Sounds to me like the High/Low beam switch has gone bad.
