- Check all related fuses & relays – all appeared ok – micro fuse not blown at the speaker wiring harness plug? Check for power going to the speaker harness – no good. Examine wiring diagram to check for source of power. Found power comes from trailer wiring! Found the 30 amp maxi fuse for the trailer backup battery power blown! Replaced fuse & check for power going to speaker – good. Attempt to determine source of failure. Possibly from when trailer was hooked to the truck? Connected to bluetooth & verified all is good.
