Hi, this is my first post, thanks for providing such a great forum, I am sure it will come in handy from now on.

I have a headlight problem with my 1999 Grandeur XG 3.0, I have onwned this car from new and have had it fully serviced (every 7500km) by Hyundai. It has done 148,000km now and has been an awesome vehicle.

The headlight low beam does not work. When I turn on low beam, the parking lights are on but not the headlights. The fog lights will work if I switch them on and high beam works as well. The tail lights all work. I have checked all the fuses I can find and they are all okay as far as I can see. I even swapped some of the bigger ones in the engine bay fuse box but still no good. Above the fuse box under the dash are some relays etc. I cannot easily find any information on these and I am wondering if these might be the clue to my problem. Has anyone had this problem before or does anyone know more about the light system and what the problem is.

Lots of views but no answers???, looks like you guys are just old fogies like me who really can't be bothered any more . And you were all waiting for me to go to the dealer and pay through the nose to fix my headlights and then post it on here so you can file it in your list of fixes. Well I've been driving around with my parking lights on and the fog lights on and it works fine for now, I can use the high beam when things get a little hard to see. :P I am going to wait until I go in for the 150,000 service and mention it needs fixing, that way at least I don't have to pay for labour on what is probably a very simple problem.

Steve, take a look in our owners manual, it will tell you where the high & low beam relays are located.

Most likely under the hood. Odds are the relays are identical & all you need to do is swap them with each other and see if your low beams now work.

Thanks 87-XLT, I managed to find the full manual at the following site
http://www.hmaservice.com
I checked wiring diagrams, swapped relays and replaced fuses ad nauseum with no luck. I am now down to checking for a loose wire or connection, faulty main switch or some sort of hyundai voodoo curse. My bet is on the latter after chatting with a Hyundai car salesman the other day he was scary!!!
I am checking with the wreakers to see how much they want for an indicator and light switch stalk because no doubt they cost more than a new car OEM from Hyundai. I will keep you posted.

yeah, it figures that it would'nt be something as simple as a bad relay.

Looks like the only thing left is a bad dimmer switch. Or the "Hyundai vodoo curse." LOL

Good luck with it, will be interesting to see what you find.

Does the low beam relay click when you operate the dimmer switch?

Well Brazzel, funny you should say that, I was at the Auto store today purchasing some spray grease and saw a pair of 55W H7 XEON globes to suit the XG. So I bit the bullet thinking what have I got to loose, forked out $35 bucks and waddaya know, I have headlights. They must have both blown at the same time!!! or maybe if one goes, they both go, I am not game enough to touch them again to find out

I would love to know the chances of both headlight globes blowing at the same time, maybe I should by a lotto ticket, I think I have more chance of winning.

LOL....I feel ya. Glad you got it. I had Silverstars in my Toyota Solara and just the low beams on both lights blew at the exact same time. Had me going for a while too. Tryed again and it happened again.....Found out the Yota doesn't like Silverstars.

I looked here yesterday and didn't see this.

2001 XG300L

Wifey reported both headlights out, husband suspects that one was out and she didn't notice til both were out, but I digress.

First stop is the under dash fuse panel which was clearly placed to encourage a 50 year old 6'4" 250 lb man to take the car to the dealer. But I had a back up plan, my 15 YO Daughter. No blown fuses, check.

Next stop, under the hood fuse panel. And since Hyundai saved that money on ink to mark the numbers, the only real way to figure out which is which is to count over and down. Headlights are fuse number 12. (which means nothing) So I checked that fuse.

(All the while, I have the lights on with two new bulbs installed and hanging.)

Still nothing.

Then I swapped out the relay for the head lights, there are about a dozen of the same relays, so that was easy enough. Still nothing.... but you have your clue.

Unknown to me, these little relays will not fire with the lights on. Or maybe even restarting the car, I don't know.

After screwing around with this for an hour and a half yesterday, I woke up this morning dreading the trip to the dealer. I get in the car, start it up and and Bam, headlights are on.

Bottom line is that it was probably the bulbs, but after you install them, you may want to restart your car before you rip the dash apart or try out for the senior Olympics in the limbo fuse checking event.
