no headlights,Help please

[zipperhead93]

while driving home last night I went to switch to high beam and then all I had was my running lights without either high or low beams, I do have a snow plow and the lights all worked just fine the day before. Since I had a problem before and just threw parts at it, I already have a new on-off switch and a new dimmer switch that are brand new not installed. all the fuses have been checked or changed, the new switch was installed along with the new dimmer switch. the wires all looked good and the bulbs are fine, and we also unhooked the plow so thing should work buuuuutttttt nothing
any ideas would help

I hate to insult your intelligence but, I jumped in a company plow truck once and my knee hit the toggle switch that changes stock lights to plow lights. maybe?

not the problem there is no switch to flip they automatically switch when you plug the harness in up front. but thanks anyways
