Suburban Headlights Malfunctioning? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I know my rig is a little newer for this Forum, I'm just exploring everyones knowledge out there.

I have a 98 Suburban, 1 headlight went out, so I replaced both low beam bulbs, worked fine for about a week, and now daytime running lights work fine, but when I turn the headlight switch to on, the headlights go out, and the brights don't work either, but if I turn the switch to the off position, the daytime running lights work fine, not sure what this problem could be?? Headlight switch?? Relay?? I sure hope someone out there has had the same problem.

Thanks,

ANDY

had the same thing happen on my dads 2000 NBS tahoe. we replace the headlight switch =nothing replaced the bulbs= nothing replaced some wiring= worked for a while then quit. IT ended up being a malfunctioning high beam switch. so we replaced the turn signal/wiper/highbeam switch and worked fine ever since

That's odd it would be a high beam switch affecting both beams. I think I'm just going to check the relay which is the center point and go from there.

Maybe the headlight switch? but why would the daytime running lights remain lit, are they on a different circuit?
