After about 4 months of working on my junkyard bought Toyota I've got it running, not well but it moves. Now I've gotten to the lights part of my adventure. I replaced all the bulbs in the tails and resoldered and heat shrinked all things that I deemed necessary but I've still got issues. My Hazard lights work awesome, all 4, but I can't get a SINGLE turn signal to fire up. I also have rear tail markers but no brakelights. Anyone have any ideas on where I should begin my electrical quest to slay the gremlins taking over my truck?:cry:

 

You could change the flashers. Probable culprit would be your turn signal switch. There could also be a loose conection somewhere. Inspect the fuse box at the signal fuse (if there's fire on both side of fuse then it is a switch problem. If there's no fire, then there's a loose conection in the system). Hope this helps even at the very least.

 

Start checking for power at various points along the wires, I know its tedious, but it will help narrow it down quicker the guessing.

Check all your grounds, make sure you have everything grounded properly.
