GRRR! Turn signals not working!

Hi folks. New to the forum. I have a 99 Cherokee Classic (2WD) and my turn signals have quit working, Hazards are fine.

My first thought was the relay (behind knee blocker.) I replaced it, but no change. Second thought was multi function switch, but that didn't fix it either. Any ideas? Thanks

They had quit working a while ago, and I think I checked them at that time. But I haven't checked since replacing the relay and switch. That would be a big "DUH" moment, but I'd eat a big slice of humble pie to have the problem solved. Is the turn signal a separate fuse from the hazards?

According to the manual I saw they share the same 10 amp fuse.
Good Luck.

Yeah I saw that, too. Hazards are fine, so it's still a mystery.

My '91 has two flashers under the dash. One for hazard the other for turn signals. Thought I had to replace the turn signal flasher the other day but found out by wiggling it a little it made new contact and was OK.

my wife's zj did this. we had to replace the switch itself(on the collum). it was easy, three torx to remove cover, one with a hole in the center to pull switch off. if you do this and it has airbags, make sure you disconnect the battery. when we did this, they didn't work for a few miles, but once i drov about 2 miles, they were good.

Junction block? Under the hood, or passenger kick panel? Or are there fuses elsewhere. I visually inspected every fuse in the two I mentioned.

ignition lock cylinder?

Still needing to get this fixed. Hven't messed with it in a while but I need this vehicle running. I found a service manual online that has a lot of detailed information about which wire powers what. I see that there are two circuits supplying power-an unswitched one for flashers, and a switched one for TS. I HAVE been having some trouble with my lock cylinder. Sometimes I turn it off, and it's still powering stereo, windows, etc. Could THAT be the problem?

That sounds like your ignition switch or the linkage from your key cylinder to ignition switch mounted on steering column. Could be the inside of your lock cylinder is worn out....

Not sure on door locks, that is separate system all together, your turn signals is one big gang of contacts in the switch in the column
