Only right taillight working?

[JBigelow]

Hey guys,

Got a 92 Dually 4WD. Kind of Puzzling. Only the right taillight works in the rear. The rear fender lights don't work either. I have turns and brakes though.

Any ideas? where can i find a wiring diagram for the tail lights?

thanks for any help!

Have you checked it with a known good bulb?



The Bk/Yl wire powers the running and tail lights. The left side and all markers are on the same circuit, as the taigate plugs in on the left side. Might be a wire broken, or a plug in came unplugged.

Yeah, I think dpuckett nailed it, everything is fed from the drivers side but there are several plugs in the rear on both sides I believe. Will require some some up close and personal "quality time" under the rear of truck. bg
