Headlights won't work

I just bought a 97 TJ from a private owner. She mentioned in passing that she just replaced both headlights. Once I got her (the Jeep ) home the headlights stopped working. All the other lights work fine (dash, dome, parking, etc) except for the headlights.

The Jeep didn't have power distribution center cover (on back order) so I don't know what is what in the PDC but have taken out and switched around the 3 relays that are identical in the PDC. First of all, can someone take a digital photo of their PDC cover and post it so I can try and track down the headlight issue??

I have used a test light on the harness coming from the headlight switch and it doesn't seem like there is power to the headlight contact of the switch so I replaced the switch which solved nothing. Does anyone have any ideas on what I can check next?? I've been trying to track it down for the past week and am almost ready to take it somewhere to have them take a crack at it...my pride, however, is getting in the way of THAT!

Any help or insight would be GREATLY appreciated!!

I agree.... Fuse or relay. If its the relay, no worries, sometimes they just go bad. If its a fuse... Fuses just don't blow. There has to be a dead short somewhere in the system. Bear that in mind. Cuz, sometimes tracking down a short can be very labor intensive and time consuming.

All the fuses in the PDC look fine but again, not sure which is which. There is no fuse in the fusebox behind the glovebox that would work the headlights so I am assuming it's in the PDC. Does anyone have either a manual and can describe which ones to check or photograph of the PDC so I can track it down?

On the 97 and 98 the headlight switch itself is notorious for going bad. I've had to do both my 97's about 3 years ago.

My thoughts exactly too, I had to replace my '97 TJ's headlight switch 5-6 years ago. Luckily it's a very easy swap that only takes a few minutes. There is no relay for the headlights so if the fuses are all ok, it's the switch.

I don't know if this will help...its from my 99 TJ.



I don't think the cover will give you the information you hoping to find. It says (if you look closely) to refer to your owners manual. Its easy enough to use a multimeter to test the fuses though (you'd do it anyway, even if you knew what the exact fuses were for). I'd have to agree with everyone else that the headlamp switch is likely the problem. Looking at my wiring diagram, power from the battery goes through a 30 amp fuse in the PDC (big fuse, second down on the left side in the picture), and feeds the switch. It looks like this same fuse also feeds all of the instrumentation lights (via the second fusebox behind the glovebox), so if you have interior lighting, your 30 amp fuse should be good. With nothing else between the switch and the lights, I'd say thats the problem.

I was also wondering if the brights worked ? Might make sure the bulbs didn't burn back out. If brights work & dims don't ( & bulbs are good) might check into the dimmer switch. Or maybe the whole problem could be in the dimmer switch or headlight switch.

He said he replaced the switch already.I would say it is the relay if it does have one.Jerry are you sure the other relay beside the fog light relay isn't for the headlights??If so it is here http://www.nakedjeep.com/Projects/Lites/Lites01.html

The wiring diagram shows that the other relay is also for the fog lights, so there are two relays for fog lights and no relays for headlights. It would help if we knew if he has daytime running lamps as the wiring diagram shows that too. It gets complicated real fast.

Have a look at the wiring diagrams for my 99 TJ (THESE MAY OR MAY NOT BE THE SAME FOR HIS YEAR MODEL)...4 scans in total because you have to jump all over the place in the book to follow the circuit.









The way I follow it, power comes from the battery, through a 30 amp fuse in the PDC (picture in earlier posts), then to the headlight switch, then the dimmer switch, then the lights. The circuit is completed by a ground (G102, G103) on the fenderwall behind the headlights.


From the connector pinout scan, it looks as though you should have 12v on pin 8 of the headlight switch connector if the 30 amp fuse in the PDC is good. If you have power at pin 8, pull the switch on for headlights, you should then have power at pin 2. Power from here feeds pin 2 on the dimmer switch. Pin 1 on the dimmer switch is low beams, pin 3 is high beams. If you look good there, make sure you have good grounds at the headlights.

If he has already changed out the switch, then he needs to check the 30 a fuse in the PDC and wire going to the headlight switch. I'm not seeing anything else on the wiring diagram.

Sorry for the delay in the posts..Wow, thanks to all for the help, photos, advise, etc...I do NOT have daytime running lights, I already changed the switch, the 30 amp fuse in the PDC is fine, the ground behind the headlights is fine...talked to a tech at the dealership and he thought it might be the dimmer switch on the steering column but I haven't had a chance to check that out yet. WHAT A PAIN IN THE ARSE...I am quickly reaching my "bring it to the dealer" limit.

Oh dang... I totally forgot about the multifunction switch! I bet that's where your problem is. I worked at the Jeep dealer back in 97 and seem to remember a run of those things that had to be replaced under warranty on both the TJ's and the XJ's.

Yeah, those are kind of a pain in the butt to replace if you've never dealt with removing an airbag or clock spring. But.... It is doable. just be careful to disarm the airbag first.

I'm having a similar problem with my 1999 Wrangler. Headlights, backup lights, license plate light and instrument panel won't light up. But all other lights (turn signals, dome lights, and engine status lights) work. If I hold the high beam lever back then the headlights will come on, but go out as soon as I release the lever.

Sardog, replace the light switch.

CCAIN: to replace the indicator/high beam/hazard combo lever (dimmer switch) you do not have to take off the steering wheel or clockspring.

several people have asked if u tried the high beams(dimmer switch).. that may help pinpoint the problem..
