Low beam flicker!!!

This is driving me nuts. When im driving with my low beams on they will shut off for 5-10 seconds or more at a time. My markers lights stay on, my guage dont dim either. I can run blinkers, wipers at same time and it doesnt turn them off. It seems like vibrations cause it but the other day i pulled it into my shop turn them on and jiggled the wire to the housings, nothing. I then moved the grounds on the front panels near the headlights and still nothing. I dont think its a loose wire but maybe it is. Possibly the blubs or connectors?

We had this problem on a 98 crown vic, turned out to be the multifunction switch (turn signal/wiper/bright stalk)

I think the multifunction switch is what's causing my LH low beam to randomly cut in and out. New headlight switch and connector with pigtail.

I do remember one night it was doing it and i ended up turning the knob some and it stayed on all the way home. Maybe something to do with the knob? Contact points?

Same problem in my 99 though it was just one side. Turned out to be bad connectors. Bought a set of heavy duty/ high temp ones for about $15 and replaced them both. Might be worth a try first unless both are flickering at the same time. Then it sounds like the main switch on the dash.
