'88 F150 No Brake Lights or Hazards

[davadms]

Greetings, Recently Lost the Brake Lights and Hazards on my Truck. Here is what I have done so far and still no luck. Any suggestions would be appreciated.

Fuse OK
12V at Brake switch and Flasher unit
Brake switch good
Replaced Flasher Unit
Replaced Multi-function switch in steering column
Turn signals and Tail Lamps OK.
Replaced Bulbs.
Inspected wiring Harness.

This one has me stumped. The schematic shows wiring and grounds the same for turn signal or Brake lights. Am I overlooking something?

Thanks

Trace your wires along the framerail. My old work truck had the same problem and we found were that the wires had worn through. One thing though, have you had a problem with blowing fuses?

Thanks for the reply, The fuse has not blown.

Do you have a trailer kit installed? if so check the connections. Do the front hazard lights flash?
