Headlights go out

09-06-2003, 08:05 PM
I have a weird one with my 1993 J30T. The right headlights turn off after about 5 minutes, and thereafter come on and off at seemingly random intervals of about 5-20 mins. Neither the high or low beams work when the right side is off. When the low beams are on, sometimes putting on the high beams turns them off. I have replaced the bulb in the low beam but it didn't change anything. Anyone got some ideas before I spend a fortune at the dealer?

Hi I had the same problem Itís the headlight relay its located on the left side of the hood itís a black box closer to the windshield sometimes you can hear it tick when you turn your headlight on and off you can order the part online everywhere I cant name any place because advertisements arenít allowed should cost around $40 if you have time you can do it yourself its only a little hard because itís a tight spot but the relay its self just snaps in and out
You can email me if you want more info
hope i can help

Mine had a similar problem and I had the dealer replace the relay but it didn't fix it. They looked all over and after repeated attempts to locate the problem they finally discovered a loose wire in the TRUNK!? Maybe something to do with the taillights?

Thanks for the help all. I got a new headlight relay and that fixed it. I replaced it myself. If you unscrew three 12 mm nuts from the left wheel well, it allows you to move some control module aside so you can get to the headlight relay.

I am having a similar problem with the left headlight. I do not have a dealer nearby and can't seem to locate the relay using the wiring diagram. Can someone contact me or post a reply here that might assist me. Also, is it the standard relay that is used in the main fuse/relay box? Thanks for the assistance.

I also have a similar problem with my 95 J30t. I think the culprit must be the headlight replay. Could anyone please give me a link where I can order the relay online?

My email address is zhoujunok@hotmail.com

Thanks a lot!

I'm assuming you have a U.S. model , not Can.w/DTRL.The relay is located where the l/ fender meets the firewall.Access is gained by removing the 3 nuts{inthe wheel well} holding the cruise actuator.The relay is black and 3" square.In my 10yrs. as Infiniti tech. The only reason these relays fail is they develope "dry solder connections" where connector terminals meet pc board.If your good with a solder gun and have a magnifier glass{to spot bad connetions,look closely as I usually find 3-5}you can fix it youself.If not, take it to a tv/radio repair guy.Ask them to repair "dry solder connection".You may chip the relay case by trying to remove the pc board from the case.Done carefully you won't have problems.If you do chip it , Make syre when your done you seal the case with silicone or WEHY.

hey guys i just replaced my headlight relay yesterday. Its a double gang relay with 4prongs on the left side and 6 prongs on the right side its located under the hood on the drivers side on the left front quarter panel next to the brake master cylinder in the corner. I called a dealer and was told it was about $51.00, went to a local foreign car junk yard and got it for $30.

Thanks infinman!!!!! I repaired my relay as you said and it solved all my problems!! (Well,at least those related to the headlights). The only thing I did different was to solder ALL the solder joints, since I wanted to make sure I got the bad ones. Theres only 20-30 joints anyway and they are all large. I only added solder to a couple of them, as there was plenty of original solder on most all of them. I just heated each joint with a soldering iron till the solder liquified.
