Rear Tail Light Turn Signal Not Working

[kemo sabe]

As in the title just recently my 91 ck1500 rear tail light turn signal is not working. I've changed the bulbs and when the lights work when they are on and when braking. Just when I try and use the driver side turn signal it does not work. Any suggestions would be appreciated.

Circuit board is fried is my guess fairly common problem.

That's what I was thinking too. The circuit board is the plate where the lights plug on one side and the wires on the other right?

That is it. A simple check if you have a test light or multimeter is to check for power at the plug in.

You can go to the bone yard also. Then you can do the double brake light mod while they are out.

It's really an easy mod, first take the circuit boards off the lights.

You'll see that that both bulb upper and lower are dual filament bulbs. But only the lower lights with the brake/turn light.

Carefully make the small holes bigger where the circuit board connects to the plug so you can solder some wire in.

Then route the wires up to the upper bulb and solder them to the "bright" side of the bulb the other side is the parking/running lamp.

Things you'll need are wire (I just used some old speaker wire I had laying around) solder iron/gun, solder, wire strippers, test light, and a 12volt source and some jumper leads to track down what connector goes where.

This is the exact one I used.

Thats pretty cool. I may have to try that out when I get the new boards.
