So I have an 04 F250 Super Duty 6.0L and suddenly the turn signals and hazards stopped working. First I replaced the switch on the steering column...no luck. Today I replaced the flasher relay under the dash panel (the blue one)...still no luck. I remember checking fuses in the fuse box but don't remember which ones I checked but I didn't see anything obvious. I also took a quick look under the dash at all the wires for any anomalies...nothing. I'm lost...can anyone suggest what to do next!? Has anyone had this issue??

Thanks in advance for the help!!!

 

Looks like fuse #27 in the underdash fuse box is common to the hazards and the turns.
