I have a 2006 Wrangler X. The blinkers and hazard lights stopped working all of a sudden. Everything else in the Jeep works. All of the parking lights come on, the cab and dash dimmer 'switch' works. I have already swapped out the flasher regulator with a Novita LM470. Fuse for the blinkers is intact. I'm not sure what else to check or what I can do to avoid throwing hundreds of dollars in parts at it. I've seen numerous other threads out there pertaining to this issue, but I don't believe I have seen a solution to it yet. Any suggestions? I'm not sure what to do next and I'd like to avoid taking it to someone for as long as possible. Thanks in advance.

Yeah, I did some googling and found it. The fuse indicated on the diagram on my glove box is intact.
The fact that it just stopped working seems to point to a fuse to me.
It just suddenly stopped working? You didn't do anything or "upgrade" anything before it stopped working?

I am not exactly sure what "intact" means without actually testing it or replacing it with a known good one as it can be blown but not actually appear to be in some cases.
Well it doesn't look burned out. According to the fuse diagram, there is spare fuse in the holder. I pulled that spare 10A fuse and put it in the designated slot and it didn't change anything.
Nope. I haven't modified my Jeep. I was just out driving, got in my Jeep to head home, and noted that they didn't work.

ya that’s a weird problem, I had a bunch of corrosion in my front turn signal once that ended up burning out the fuse and flasher relay in the steering column. The other time my flashers stopped working was because of corrosion in the back right corner where the trailer wiring was spliced in

On mine it was the plug going into the multiswitch connector. It is in the steering column. The plug overheats and gets brittle. The individual wires can fall out enough to where they don't make a connection. I replaced the plug. They make kits for replacing these.

So after looking around for something wrong, I found that I had crushed my trailer hitch wiring in the tailgate. There was exposed wiring, so I'm thinking it shorted out something. To be on the safe side, I went and got some new ATM fuses and swapped out the fuse in the glove box, but it still does not work. I feel confident that the crushed wiring was the source of my problem, but is there another component I can check to see if it is fried? How would I test the flasher relay with a volt meter, for instance?
I crushed the wires that go from the back into the tailgate and blew my fuse. If you have wiring for a trailer I assume it’s aftermarket, plug and play or spliced ? Maybe un plug if it’s plug and play ?
I just had a light on another vehicle, an the hazards when put on, caused a half working light, to work great. the semi mechanic, was yelling ground wire loose
Its spliced in. Its one I got from a uhaul. I was in a hurry and just paid them to put it in. I covered the damaged section in electrical tape, but I wonder if the wires are making contact inside of the cable at this point.

The flasher relay is cheap. They usually have it at advanced auto. I’d say just buy it and put it in. There’s your test. I knew mine was bad because it made a funny noise and smelled burnt.
Whelp, get you a voltmeter and chase it down. It’s a bad ground or wire grounding out
Same problem here. All of a sudden, no turn signal or hazards after I removed the headlight switch to replace with the headlight w/fog light switch. Plugged the old switch back in but still the same. That plug is $75 and with 20 wires, a pain to replace. I would at least check for power and ground at the correct terminals before replacing.
