[QUOTE="way8lifter, post: 1451125, member: 92881"] Okay I don't have a wiring diagram in front of me I'm on my phone I know you can find one pretty easy on here I suggest this start at the fuse box and work your way outwards by that I mean started the very fuse and relay are there power there where does that line lead to it leads to a switch source that has something to do with not only our starter button because that engages the headlights but which runs through I think the ECU again I'm on my phone I'm from there the line probably goes to a relay and from there it might go over to the headlight switch for the up down high beam low beam and from there into the headlights so find where there is power find where there isn't power and your problem someplace in between does that make sense? And I will say the very first thing I check when I have a problem with a device is where are the grounds and is it grounded and if you have something like a power probe why not directly power those headlights make sure something freaky didn't happen where you lost both headlights... By the way yes that can happen if your alternator was pumping out too much juice it can blow the headlights out ask me how I know?,, Anyway that's my simple from the phone diagnosis shooting from the hip [/QUOTE]
