My lights died on my truck too a while back. check the wiring all the way back. some how mine were sliced by something. it was pretty odd. nothing a little solder and some shrink tubing couldn't fix. hope that is the case with yours too. good luck!

Check all of your bulbs and the connectors. Had this problem with my driver side blinkers, bad connection with the bulb, cleaned it up and they worked. Will check my wiring diagrams later, right now at work.

I had this problem when I got mine. I checked all the bulbs and connectors. The problem was where the wires pass under the tray over the diff. They were severed there. Take your time and do a complete check of your wiring. Clean all connectors and check your bulbs. Not all at once, so you'll know where the problem was.
