My turn signals and hazards stopped working today. I checked all of the fuses and none were blown. I replaced them all anyway. Both under the hood, and under the dash by the left drivers leg. That didn't work so I replaced the relay under the dash by the right drivers leg. That also did not work.

What might my next steps be? People look at me like I'm crazy when I use my arm for signaling a turn in the meantime, and I don't know that it's quite as safe as actual turn signals. I would like to fix this

Edit: I just learned about the multifunction switch. I will take my dash apart and see if there is any obvious issue with the wire. Otherwise I'll try to find a replacement and hope that fixes it.

 

Not sure if there's supposed to be oil at the connection, but I'm guessing not. New part coming in tomorrow for $80. Hopefully that will fix it.

 

Got the new part in. It did not fix the issue. I can hear the relays (what are originally the red or blue ones) under the dash clicking erratically now. Not sure where to go from here. Any advice would be appreciated.

 

All the fuses?

So far as I know, there's only one, for the "combination flasher" i.e. for turn signals & hazards which means if both fail, that's the most likely culprit - but then you refer to relays (plural)

 

I changed out all of the fuses that have the two flat posts and colored tops on them. Figured why not while I was in there. Then the relay I wasn't sure if it was the red or blue box, so I replaced both of those. I also see there are circular things (Turn Signal Flasher and Hazard Flasher) that are not installed, nor were they when the signals did work. Do I need those?

 

I'm got a 3 prong Turn Signal Flasher, but there's no connections inside the circular areas for the Turn Signal Flasher or in the 2 prong Hazard Flasher. So that's not it either. I'm really at a loss.

Edit to add details:

I unscrewed and pulled the front half of the inner fuse box out, so I could see the wiring behind it. As other posts have stated on the '95, fuse slot 8 is not used for turn signals. Number 10 should be. I decided to throw a fuse in spot 8 anyway, and the signals worked! But, this was a coincidence. I pulled the fuse out again and they still worked. I tried my hazards, but they didn't work. Not only that, but the turn signals do not work again. I replaced fuses AGAIN and no change, so I'm pretty sure either wiring is bad or contacts are bad somewhere.

I never regretted buying this Jeep until now. I've replaced the floor pans, hard brake lines, motor mounts, suspension, wheels, tires, etc. That was at least somewhat fun at times. I have had too many cars with electrical issues for me to enjoy this aspect of it, unfortunately. I'll keep at it because I have no other choice.

 

OK, now I see you've got a '95 forget what I said about a combination flasher, which I think must be a '97-up thing. whereas the earlier models had the separate ones for the 2 functions.

Yes you do need them, they're what makes the turn signals flash (the clue's in the name) but everything you say suggests that yours are not where the diagram shows them. Keep changing good fuses won't help anything (except, possibly, cleaning their sockets if they're badly corroded). As you've found the flasher unit, replacing that might be the next move.

As for the red & blue relays. that doesn't help me but never seen relays those colours in a Jeep so probably not OEM. Where are they - & what doesn't work if you pull them out (one at a time).

I'm impressed with what you've done so far, so don't let this minor, but irritating, problem get to you. There are people here far more capable & knowledgeable about XJ's generally, & electrics in particular, but we need you to help us help you.

 

Thank you for the reply. I found out quickly that the round style is old, after pulling the fuse box and doing more research. I apologize for being upset and bringing it here, that's not what the forums are for.

I will get a picture of the red and blue relays I replaced that I am talking about when I next have the opportunity, likely tomorrow. I can pull one of them at a time and see what doesn't work. When I swapped them I didn't notice anything stop working, but I can test more thoroughly for that now that you mention it. A bad storm came through today and I don't have internet (using phone for internet currently). I'm working more on cleaning up the mess left from that.

I am looking to see if I can find a multimeter to do some testing on the wires, fuse boxes, and relay boxes.. I believe I need to do continuity testing from what I have researched, but I'm not the electrical wizard in the family. Unfortunately the one that is smart with that lives thousands of miles away from me now.

 

There could be a few issues, but by far the most likely is wires

these can be very difficult to trace, my '96 has an intermittent issue when the passenger (LH) door is opened, the hazards will be triggered

There is a bunch of wires that go through a rubber grommet in each door that can cause weird issues

Having said that, I suspect your issue is closer to the heart of the problem

You need a multimeter and test light to diagnose

Is there a fault finding procedure in the FSM?..posting the circuit diagrams will help you and us

You are looking for 12V at relays etc

As I mentioned previously 5amp wire can be slipped in a relay slot with the relay installed and you can backprobe for voltage

 

I appreciate the replies, and will post again when I have the time to get more into it. The main working car in the house is also having issues now, and I have a new job. So I'm doing everything I can to fix that one first. When it rains, it pours

 

We'll still be around when it suits you to go back to the problem.

It's because they were round (& a good bit bigger) that they're still called flasher cans here, but the shape's not important, what matters is the pin arrangement, so there's no reason why newer ones shouldn't plug in the same place. I meant to look at my '96 over the weekend but lost so much precious time due to rain, I completely forgot.

 

lol, sounds like how I acquired my spare '96 for $450, a nice unit but with the fuel tank and brake master cyl in the the back, blocking in the owners wifes car, which also needed fixing

He worked six days a week, 12hr days he explained to me

When I got round to pay his wife and get it towed, 3 little toddlers were crowding the mother, who I must say, was a vision of female loveliness

new fuel pump body and wrecking yard master cyl, and she is a goer

 

So, I'm back to working on the Jeep. I think I might know where the issue is at, finally. My multimeter is junk and doesn't read anything other than 1 in continuity or other settings. I was able to finally get the wiring harness going through the firewall (driver side, next to brake booster) out and unconnected. There is SO much gunk in there, and pretty much every single contact is black from oil, grease, dirt, etc.

I don't have any contact cleaner so I am using isopropyl alcohol 99%, cotton swabs, tiny screwdrivers, and compressed air to clean it out. It's going very slowly, but seems to be getting me closer to the results of clean terminals. I have the before pictures I am attaching, and will upload the after result when I am done. Probably another 1-2 hours to go.

 

I don't think that's what contact cleaner's designed for. What you're doind is definitely worthwhile, even if it doesn't fix the problem - which I sincerely hope it does.

 

Yeah, maybe I am using the wrong name for electrical terminal cleaner. Even that name I'm not sure about, but I don't have it so iso propal and elbow grease it is. While cleaning, I found one of the terminals connecting to a wire had corroded out. I don't have any connectors, so I removed the terminal connections from both sides of the firewall and ran a new cable through, and splice that into the wiring harness inside of the cabin that it did connect to. I'm working on buttoning things up now, but needed a small break. It's hot out today hah. My battery also died at some point during the last few days, so I'll have to jump it once I have it all in place again.

Here are some updated pictures with it more clean, although not perfect.
