In addition to fuses, some vehicles also have tow package relays. The best way to find the locations of all fuses and relays is to use the vehicle owner's manual. There is normally a section on the fuse's panels and power distribution boxes that lists out everything.

You might also want to check to make sure that the connector is clean and free of corrosion inside and out. Once you have checked everything and made sure all the wiring is intact you can use a circuit tester such as # PTW2993 if needed to test the connector. Have someone sit in the vehicle and go through each function while you test.

If it still does not work, then you will likely need to bring the motor home to an RV dealer with a service center to have the issue diagnosed and repaired.
