94 Silverado low headlights no working

On my truck my low beam headlights do not work the High beams work fine. I thought it was the high low switch but tried to change it and it did fix it. I think the switch is working because it turns the parking lights and the high beam lights on and off. Any ideas?

check your fuse box under the hood .there should be a relay or fuse for each headlight. should be a #10 amp .an '02 has a fuse for each running light. go figure . let us know in case someone else has the same problem..
