I was coming home from work this morning and all of a sudden my headlights turn off but all my markers and dash lights are still on. I replaced the headlight switch about a month ago with a BWD switch the plug was not melted. It wasn't the bumps in the road when I finally found the side of the road my headlights were still flickering on and off where should I start looking is it maybe a relay

 

Yes, check the relay. Then I would start checking the wiring from the headlights back, and see if you find a wire rubbing against something or a short.
Flickering on and off sounds like a loose ground or ground issue.

 

I will check it out in the morning thanks

 

Not a relay. If a relay goes, the lights don't flicker. You already got some sound advice; checking the wiring for an intermittent ground is a good idea. I'd wager your new switch failed, though. Borg Warner (BWD) used to make high-quality parts before they were bought out by SMP Global. Now that switch you just replaced is Chinese-made and unreliable at best. I've had two BWD VSS failures in as many months on the second gen.

Just something to chew on while you chase wires.

 

When I had headlight problems it was the highbeam/signal switch in the column. I didn't have time or $$ to get a replacement, so I broke out the relevant wires from the switch and extended them to an oldschool floor mounted pushbutton.

I still havent changed the column switch....

 

Listen to this guy ^. I did this before I had problems with the column switch. Heads off the BS at the pass and it's so easy a woman could do it.

 

It's been 3 days and I have had no issues after I changed the switch. Going to run through the wires and grounds just to be safe this weekend
