Ok so I was out plowing yesterday, and my main 20 amp fuse for my parking lamps blew... This is after weeks of trying to figure out why my turn signals have been acting up.. I ended up finding an old trailer plug harness that someone had installed and at some point cut the 4 flat plug off and did not tape up or protect the ends of the wire, the shorted and blew the fuse... So I got that taken care of, I have tail lights and parking lights, but my brake lights and turn signals do not work at all. The turn signal indicators do not light up on my dash either...

Things I have checked and replaced:

Checked all fuses (There is no brake lights, or turn signal fuse in either of the boxes)

Replaced turn signal switch in the column

Checked all bulbs

Checked what wires I could get to for more shorts

Replaced turn signal flasher

Any other ideas or thoughts??

Pick up some contact cleaner and lube from an electrical supply house, and spray the turn signal and hazard flasher switch assembly until it cleans out the gunk.

When this switch assembly gets dirty the hazard, brake, and turn signals quit or work erratically. Same thing applies to Fords!

Do not use WD-40 as that will ruin the switch. It leaves behind a sticky film when it dries.

Actually, if it is the switch, this contact cleaner solution will be a temporary fix. There's a dielectric grease in there that needs to stay, and it will also be washed out. It will be just a matter of time till it messes up again if this is the culprit.
