Noticed that my left led turn signal in the front wasnt working. Checked the fuse it was good. Reseated and all of a sudden it worked. Drove home still working. Go inside for 20.mins go and lock the truck. Boom not working. Go outside reseat fuse and it works. What would cause this.

 

what are you working on,
i dont see how a fuse would reset the turn signal, unless the terminal for the fuse is loose or has a poor connection. try replacing the fuse.
