Re: Headlights go off randomely at night time?
I wanted to chime in on this issue, as I read a million posts about it for a few weeks. I was having the same issue as so many others. Headlights both tested positive with multimeter or power probe. running lights were the only thing working for a while, then one day, no headlights at all. dash lights were always dim like it was the auto sensor.
It was that block under the dash. It was not difficult at all to get to. Remove the lower kick panel under your steering column, you'll see the block right away. remove the bolt from the center of it, wiggle it back and forth while pulling and it comes right out. The while block actually pushes up into a bunch of relays, so this is what you are separating it from when you pull it out.
chances are when you flip the block over you'll see the issue right away. I've attached a few photos of mine, as well as the wiring diagram that shows what relays are contained on that block. Part #8 on that is where the black wire connects to that was burned up on mine! anyone searching in the future should check this FIRST instead of buying switches, bulbs, sensors, and whatever else!
