I was out there today working on it...so the left park lamp up front does work, if the socket is held in the housing a certain way. The socket does need to be replaced however...the bulb barely stays in it and the contacta are messed up. The rear lights however, I'm at a loss. Tried a known working bulb, no difference. Looked under the truck to find a rats nest of wiring...somebody had wired in a trailer harness, so maybe it got messed up in there somehow. I don't know now if I should take all this apart and try to rewire it, or replace the mechanism in the steering column for the signals. I doubt it's that though. Like i said before, the left tailight works, but goes out when brakes are pressed, and also goes out when left or right signal is turned on. The lights are also now properly grounded.
