The title pretty much summed it up. I took my 02 F-450 and had the dump sandblasted and painted last week. On the way home after picking it up I noticed that the turn signal stopped blinking but stayed on. Turns out that both of them will do this and the hazards do this too. Sometimes when I restart the ignition it will blink for a bit but then the same thing happens. So during this I hooked up my trailer and checked those lights. Thats when I noticed the brake lights were out. I unplugged the trailer from the truck and yep the brake lights are out.
I would automatically go to the ground then check the brake switch (but would the switch mess with the turn signals?) and then the fuses (since the signals are intermittent)
And I dont have a wiring diagram or fuse box layout (dough!)
Any help-insight would be greatly appreciated
