I have an '04 F350 6.0L, and find that my turn signals, trip computer, and back-up sensors are not working.

I checked the fuses for the turn signals (#8 fuse location) and what I think is the fuse for back-up sensors (if they are tied with the backup lights #18 fuse location). I could have their locations backwards. Also, will any of this show up in the DTC?

I read in another thread for 7.3L that replacing the relay for the turn-signals worked. Does anyone know the relay location for the turn-signals, trip computer, and backup sensors.

 

After going through each fuse/relay. I discovered that fuse location #27 Ignition Switch Feed was bad. This fuse controlled the following items on the my 04 F350 6.0L:

• Turn-Signals (hazard flasher still worked) also because I thought it may be related to lever wipers and high beams still worked
• Heated Seats (other seat controls still worked, up/down back/forward and lumbar)
• Backup sensors
• Trip Computer
• Heater Fan Blower
