Hey guys hoping someone can help me out. I recently acquired an 87 samurai love it so far. Except I'm having an issue with the signal lights not working.
So far I've tried, checked fuses, checked relay. And I've changed all the bulbs and put new taillight housings in. I've also swapped switch indicators and still nothing.

Flashers do work. I'm at a stand still and have no idea what to do next.

Go to Ack's FAQ and find the wiring diagram, get a VOM and start troubleshooting the problem - the fact that the 4way flashers work rules out the lights themselves and three quarters of the wiring - the problem is probably somewhere in the column switch or it's associated wiring, also check the flasher switch itself.
