My Yukon's low beam headlights do not come on, ever. All of the other lights work properly. I read the User's Manual and checked the methods found there to turn the headlights off, but none were the culprit. Is the relay the problem? Thanks.

i think there is a seperate fuse for each headlight. Did you check the fuse block under the hood?

Yes, I checked all of the fuses; they're fine. Looking at the "fuse box" legend, it appears that the headlights are wired through a relay. Perhaps the relay is bad or it's the circuit breaker the owner's manual talks about. Thanks!

did you check to see if you have power to the electrical connector at the head lights?

I never heard of a relay, but if you can tell me where it is I will replace it no questions asked.

appreciate your response on this very much.

Thank You!
