I cannot for the life of me figure out whats going on. I did a retrofit and my side marker lights worked fine but now neither of them is working, I've checked the bulbs, I do not have anything spliced into those wires and the rest of my parking, headlights & foglights still work. I looked in the manual but they dont really have those lights listed in the fuse map and I pulled and checked all the fuses that I thought might pertain to them to no avail. Anybody know if there is an individual fuse for those that I am missing or have any suggestions? I put some bulb grease on those connections after my retrofit, i cant imagine that that would have done it. Help Please

 

Maybe it's just bad bulbs. Did you try replacing them.

 

The answer to your problem is simple.

You f$%#d it up.

Go back to the beginning, and start over with stuff you can handle. Remember, the peanut butter goes on one piece of bread, and the jelly goes on the other piece. Then you put them together, with the bread on the outside.

Next, find someone with enough competence to plug in bulbs to check the work you did on the truck.
