Headlights will not work on Low Beam

Fog lights work, and high beam works but low beam I have nothing.

I have went through the entire circuit.

1. I checked continuity through the main switch, the multi switch is working, I checked voltage at both and getting 12v(orange/grey). The drawings mention a relay but I have swapped around relays and the problem never moves. Fuses have been checked.

Is there some hidden circuit breakers,fuses or relays anywhere? I have been through the under hood distribution as well as the in cab. No luck.
Any help would be appreciated.

Thanks
REM

Try a new bulb. It wouldn't be the first time both headlights blew the low beams at the same time.

I looked at the bulbs and see both elements in tact and they both burn on bright, does something internal go bad in the bulb?

yes it's very possible try useing a ohm meter on the bulb to test it . as leader stated i also in my many years in dealer ship shops found both bad at one time.

Did you check voltage at the plug?

I went out to do some more checking yesterday and before I did I routinely flipped the light switch to on and whola they worked, flipped it about 3 or 4 more times no problem.I went out this morning and again "No low beam lights". I pulled the main switch back out and checked again and I am getting the continuity from the pins it's calling out for the switch, my question now is this, does the light switch unit also have the relays for park light/headlight built in or are they located elsewhere.
