"Blowing" FusesYou don't say which fuse, but since the issue is related to "backing up" I suspect that it is the fuse for the backup lamp circuit.

If that's the case, then it is caused by one of two things:

  • There is a "short circuit" condition in the wiring circuit for the backup lamp circuit, or
  • You have added some power "extra" using device(s) to that circuit which causes the current draw [measured in Amperes (Amps)] to be more than the circuit and its protecting fuse were designed to carry.
