If you have surge brakes with an actuator like part # T43397007K but don't have either a manual or electric lockout then that would explain why you can't backup.

I'm guessing you have an electric lockout like # T4748800 since you were looking at the fuses. If the fuses look good then you need to check the reverse wire from your tow vehicle with a circuit tester like part # PTW2979 to make sure that the reverse light circuit is getting power. If you have a 5-Way flat connector then it will be the pin further from the ground pin (the one that looks different) but if you have a 7-Way then that will be on the middle pin.

If all of that looks good then your solenoid may be bad. Let me know what actuator you have if this is the case and I can see if we have a replacement lockout solenoid for you.
