1998 Jeep Cherokee Classic 6 cylinder 4.0L, the turn signals just stopped working while I was driving it. The hazard warning lights don't work either.
I checked the fuses, no go there.
I've tried replacing the flasher unit with a brand new one. Still not working.
I tried replacing the multi function switch, and the switch itself doesn't seem to make a difference either. (I returned the new switch, but I still have both flasher units)...
Any ideas?
Did I buy a faulty flasher?
Is there something I can do to check the rest of the circuit easily?
Does anyone have a wiring layout diagram that tells me where I can test this stuff?
If it's the switch, then why did a replacement switch not work?
Does anyone have a pin out that will enable me to test either the switch or the flasher or the circuit?
The flasher connections seem straightforward enough, TS, HAZ, IGN, BAT and GND... I'm thinking with the ignition on I should have 12 volts between IGN or BAT and GND. If I don't then it's probably the wiring up to the flasher. If I do then I should be able to supply 12V to the TS and HAZ terminals and then if the wiring/multifunction switch works (but without flashing) then it's the flashers. If it still isn't working it's the wiring between the flasher and the switch (probably).
Must be the switch as turn signals and hazards run on two different flashers.
Not on the 1998... It uses a single five pin flasher marked IGN, BAT, GND, HAZ and TS... This makes me think it has two inputs, a ground, and two outputs. One input is constantly on and "flashes" on the hazard output, the other input is on when the car is on and "flashes" on the turn signal output.
With the help of those diagrams and a multimeter I probed away at the flasher socket and discovered that I had exactly what I expected everywhere... EXCEPT the BAT connection... I expected that to be a constant +12V (or so) but in fact I got nothing.
Consulting the diagrams you provided I spotted that that connection was fused, but not in the passenger compartment fuse box, but instead in the under hood power distribution centre. I quickly looked through all of the 15A fuses there (they're helpfully not numbered or labeled) and found what was obviously the culprit. A blown fuse.
I replaced that and everything works again. In future I guess I'll check the fuses under the hood as well as those in the passenger compartment whenever anything fails.
I am having this issue with my 2000 XJ. No hazards, no turn signals. I have replaced the flasher relay, and checked for voltage on the terminal marked B. Voltage was on. Checked voltage in the socket marked I. Voltage came on when ignition is on SO fuses seem to be good. Previously I had checked all 15 amp mini-blade fuses in under hood junction, and the number 12 position fuse on passenger kick panel. Are the Turn signal and Haz switches integrated in the column? it seems odd both would be bad. Is this connector hanging in the breeze supposed tobe connected

to anything?
The community has helped before and I’m gonna need it again. I have a 98 Classic that worked perfectly up until now…I had put in all the A/C components and been messing with that. Soon as I finished I went to leave and discovered my turn signals not flashers had been working. They have been working perfectly up to now..I did a little research and most said the relay…I had changed that out with a new one and nothing changed..is there anything else I can try or do to fix this? I’ve already checked all my fuses and they have all come back good

Turn signals and hazards not working...
