Low Beams dead, Hi Beam Fine?

Yes I just tried a few things.... Replaced the light - same issue. Then swapped the relays, ... same issue. So relays are good, lights are good. Next will be that switch on the floor. Maybe just came loose or corroded. I did have that issue when I first got the car... that floor switch had completely fallen apart. Of course what I do in the meantime is just drive around with the hi beams on even those high beams are nothing like the modern low beams on newer cars. no one ever flashes me. good ideas guys. thanks
