I was driving my van a few days ago and had to pull over to help someone stranded in the ditch. Well I tried my 4 ways, nothing. Signals work but no hazards. So thought it was the metal relay. Nope. Not even a new one i took out of the package worked. So now I am thinking fuse. But when i looked at the panel, All were good. What could be causeing this? Anywho, i pulled him out with my chain on my hitch. So any help for the hazards? Thank you.
