no turn signals or hazards

I've got a 1997 Wrangler and the turn signals and hazards quit working. I checked all bulbs, checked the fuse behind glove box, checked the fuse in power distribution box, replaced the flasher under dash, and then replaced multifunction switch. No changed either time.

Hate to take it to dealer, but what the heck!!

Check your Grounds and change your relays.

While my problem was hazards and brake lights, my hazard switch was full of gunk which kept things from making the correct connections. I flipped the switch back and forth about 20 times and they started working. '97 also, by the way...


Merry Christmas... RT

Does all of your side marker and parking/signal lights turn on? I had the same problem with my 2002. I had to replace the flasher just to get my lights to work. I then noticed that if I reached under the flare on the passengers side that when I touched or wiggled the wires, that the lights would come on and off.

Even though the lights were working I still had a short. I went to a junk yard and bought a side marker and signal socket. I was able to cut the piece off at the JY so I cut the wires back a ways, and then cut mine off and spliced the wires together and my hazards and signals started blinking again.

Not sure if your problem is the same, but I would bet you have a short somewhere if it isn't the flasher. Not sure if you said you replaced that or not.

Have you added any mods, like taillight guards?

I bought the jeep with the brake light protectors already installed by previous owner. What are you thinking may be the problem?

They are known for losing their grounds. Remove them and make sure the bolts that hold the taillights make good connections.

l try that, thanks. Someone else mentioned changing the relays, but not sure where they are. Any help here?

Also, driver door handle just "popped" when I tried to get out. Had to climb over to passenger side. It will not longer open from the inside. I
guess this means taking the panel off, right?

Not sure what relays they are talking about. Take the guards off first.

Yes you need to remove the door panel and hook the rod back on the handle mechanism. Mine did it over the summer and once I hooked it back I tied it on with a twist tie. Their is a plastic clip that holds the rod on and it broke. You cannot buy just the clip. You need the whole handle from the dealer. Not very expensive but a twist tie is real cheap.

I had this problem in my old Jeep. It was the signal relay or what many refer to as the "Turn Signal Switch" usually under the dash. Easy fix. Expensive part.

No turn signals or Hazards

Had the same problem with my 99. Replaced the multifunction switch which did not fix it. Turned out to be a bad hazard switch.

hey yoopone, I replaced the multifunction switch mounted on the steering column. Doesn't this contain the hazard switch also?

Sailingking22, I replaced the flasher located under the dash near the steering rod. Is this the one you are talking about?

Thanks guys

Sorry I was not clear about that. It was the blinker switch, or the blinker box what ever you call it. The Jeep sits at our condo in Florida when we are not there. I am having every switch type device go bad one at a time from sitting. Right now it has a flakey headlight switch. I must be the salt air. Jeep is in a car port, but it is very close to the Ocean.

XRAYJEEP - Yes, that was the one I'm talking about and Yoopone is talking about the same one too. If you've replaced that with a good part it might be time to take it to the dealer. Ask for a free diagnosis (call them up first) and maybe you can avoid the fee. Of course, I'm always so warry they will simply break something else why they have it there. The only other thing I can think of off hand is if you have any aftermarket wires plugged into your wiring harness (maybe a trailer light kit by the hitch/KC Lights/stereo). Unplug those and verify the problem is still occuring before taking it in.

No turn signals.

After checking all the grounds and all of the relays(flasher, Main relays under hood) I replaced the turn signal 4 way unit in the steering column. It took about 35 minutes and cost me about $65.00 from the dealer. I had the chance to pick up a used one, however there are no guarantees that it would work and for how long. So I bought the new one. I hope this helps all you Jeepsters good luck!

O4 TJ The fourway turn signal unit is in the steering column, behind the steering wheel. It contains the turn signal switch, headlight high beam switch , and the fourway flasher switch. I'm unsure how the 04' unit is disassembled. My 99' was simple with average mechanical knowledge. Without removing the steering wheel I was able to pull the cover and remove/replace the switch assembly. If you are not sure of your capabilities take it to a mechanic! If you are sure, it was a simple inexpensive fix that cured all my woes. Good luck.

04 TJ you might want to check your plug connections for corrosion build up. Clean them up and use a tiny amunt of dielectric grease making sure not to bridge any of the connections.

Mine quit after driving about 30 or 40 minutes. After I turn the Jeep off, they come back eventually and work for another 30 or 40 minutes. I have discovered that they do not quit if I don't run the heater. I'm thinking that the hot air under the dash is heating up the flasher which is also under the dash. I'm still in the investigative mode. Not going to do anything until they quit altogether. PITA UR

I have the same problem .. Mine all started with a buzzing noice coming from the steering column when I turn the indicators on, then it just died... I replaced the flasher unit, check the fuses and bulbs, but still nothing, no indicators and no hazards, the rest all works fine

It seems there's plenty on here with no resolution. Count me as yet another one.
I drove without fogs for about a year until I got around to installing a new Duralast MFS from Auto Zone. I regained access to working fog lights, but lost turn signal and hazard lights. I thought it was a bad Duralast MFS, returned it and picked up another. I got a bit of a flicker out of the second MFS, but now there's completely nothing. All fuses seem to be good, I'll have to poke around for the "Turn Signal Switch," but I'd appreciate hearing if anyone has any other ideas.

There is another fuse under hood as well (where the relays are located). Make sure all the fuses are good, and the contact points are not corroded .. This was my issue!!

I think I've found the issue. I found on another thread on WF (link not available from my phone) that showed where a hazard relay plugs into the back side of the MFS. I, like many others, did not get the critical scoop that you need to pull this relay BEFORE you discard the faulty MFS.

I scrounged a relay from the under-the-hood fuse box (the one for a locking diff) and will use that until I get the proper hazard relay from NAPA ($35). I had read elsewhere that the Duralast from AutoZone ($60) doesn't quite work right. FYI, the diff relay won't allow the turn signals to blink, but you wouldn't want your locking diff to switch on and off at blinker rate either.

Thanks to all on this thread and others on WF for the awesome help.
