I would use a light tester on the 12volt fuses as sometimes the fuses look fine, but are in fact failed. This fuse should be in your fuse and breaker panel. Not sure where it would be located in your coach, but usually located close to the floor and lined up with where your shore power comes in. If there is an inverter on the same line as the there is a small chance there is a fuse or breaker on the inverter that is messing up your power.
You may want to try a different 12v power source to ensure the hardware has not failed, or test something else on the 12v source that is giving the issue.
Sorry I am not familiar with your coach, but I hope that helps you track the issue down.
