Rear blinker won't work

Ok no blinker fluid jokes. My front left blinker is blinking really fast and my left rear is completely out. I replaced the rear bulb and the socket/unit today and nothing. Where next, circuit relay. Any help would be appreciated,

Your front signal indicator is hyper-flashing, because it senses your rear signal as being out. First, try swapping a socket with the reverse light (police won't stop you for a reverse light being out). If that works, then you know it's a socket problem and you can try bending up the contacts a little. If it still doesn't work, just buy another whole tail light assembly off of eBay. They really aren't worth the time trying to mess with, unless your finances can't take it. In that case, you can take it apart and try to fix or replace the "circuit board" that is inside. Do a search on tail light assemblies. Someone, within the past three weeks, posted how to take those apart, where it usually fails, and how to fix it.

Ok took it to my mechanic today as I could not figure out the problem. My left rear blinker was not turning on, however the front one was blinking fast. So we swapped the right rear blinker which worked over to the left one and nothing happened. The tested out the the voltage and it appears to be reading a negative charge but nothing positive within the piece that connects the wiring harness to the light assembly. So at this point its either the relay or somewhere along the wires from the fuse box ( under the steering wheel by brake ) all the way to the end of the wiring harness that connects the light assembly. I think I will leave this job up to my mechanic, last time I tried fixing something electrical I ended up making it worse.

I think it could be the flasher unit. What happens when you turn the 4 ways on?

When I turn it on, three of them work, except for the left rear blinker. Its a mystery because the back up light and brake light work, but not the flasher. I think your right, im going to purchase a flasher unit today. Im not familiar with flasher units/relays, but are the individual units/relays for each blinker or one that handles all four blinkers? If its just one relay unit, then maybe it actually could be the wiring?

You are right. If it's not the flasher unit then it may be the wire but I just thought of something else~the turn signal switch :-(

Unhook the left and right tail light assemblies. Verify the connectors are the same. Plug the right side tail lamp assembly into the left sides connector. See if it works then. 9/10 Jeeps with this problem either need a new socket (tested by switching the socket from the reverse light), a new bulb, or a tail lamp assembly.

Im glad someone came along with the right info.

Its not a relay or a flasher. The blinkers AND hazards use the same flasher (combo).

Like Dealer said, 9/10 WJ's are going to need new tail light assemblies. The circuit board most likely has some broken solder joints. A new pair of assemblies will run you like 60-100 bucks new on ebay. Probably less than you paid the mechanic.

Okay I figured it and I have to say, these things continue to surprise me. I did everything from switching the blinker lights around, buying a new bulb and socket unit, to even inspecting the wiring. I finally purchased a new relay and was going to install it the other day. I opened up below the steering column and decided to "wiggle" the existing relay around just to see what happened. Turned the car on and the left rear blinker started working again. I think it must have lose however it seemed to be in there pretty good. Such a pain the in a$$ for just a little blinking light.

Thanks for all the help guys
