turn signals and b/u lights don't work

[xipantera31ix]

Like the title says, my backup lights and turn signals don't work. I have done a bit of troubleshooting but to no avail so far. I have power to the fuse circuit, none at the flasher and none at the light sockets. I have replaced the directional switch, headlight switch, all fuses, flasher, checked all bulbs, nothing. Can anyone help isolate this a little bit more as to where to look for where it could be messed up? Any ideas?

check the ground for your tail lights...that's probably the problem

[xipantera31ix]

where is that ground located? I'm assuming on the bed somewhere....

[JeepcoMJ]

it is either behind the left tail light or underneath the bed in the middle. just trail the wiring and you can locate it easy enough.

Ok thank you! I will check it out soon. I don't know if it makes a difference, but my front turn signals are out as well as the rears. Could it possibly be because of a backfeed from the rear ground being out as well?

there is a fuse for the manual tranny's backup lights, it says trans over the slot. that solved my bu lights problem

[JeepcoMJ]

check the flasher thing on your fusebox too...make sure it's not corroded or junk.

 

matter of fact...is your truck stick or auto?

Rear lite ground is behine the left tail lite, could effect front turns.

 

Also check the conector on left frame rail, about a foot in from rear bumper. The rear harness has open crimps on the line that corrode, I just tear it all apart and redo all crimps w/B-caps and no-oxy.

 

As Oizarod115 wrote, the fuse is 7.5 amp on the FB or it could be the switch on the tran'y

 

More likly, your problem is in the wiring. Seeing that you changed all of the switches.

Its a 5 speed, and the flasher was tested. Ill check all the grounds out, and I really hope I get this fixed soon, All I need is a front bumper since I decided the factory one isnt quite jeep enough for me, as well as this clusterf&%* and it can be inspected, re-geared, and trail ready. I'm shooting for memorial day to get it all finished :USAflag:

If it's a 5 speed, is your slave cylinder leaking? common problem with those is they leak and the fluid gets into the fuse box and corrodes it.

[xipantera31ix]

I believe you mean my master cylinder (on the firewall) and yes, I just replaced it because it was leaking, and I replaced the fuses because they were corroded. How should I clean up the corrosion? Pull the fuse block?

[JeepcoMJ]

yea master cylinder. pull the fuse box back and look how corroded it is...you may need a new one, or you may need to pull every connection and clean it...but if your fuses were corroded then that's 90% of your problem.

Am I pulling the inner section of the fuse box? Is it just the 2 mounting screws? Any tips/ tricks?

[JeepcoMJ]

just the two screws. pull it back and see how bad it is...hopefully it's just mild corrosion that you can clean up.
