Solera Smart Arm Awning Non-Responsive

[Twisties]

We have two. The front awning operates normally. The rear awning is dead.

When we try to operate it from the In Command panel we hear a solenoid (I assume) engage in the In Command wiring module in the pass through compartment. But nothing happens at the awning.

The control panel on the awning arm is completely non-responsive. No lights, nothing. Our best guess is that power is not getting to the awning, but we don't what to check. I do have a multi-meter, just not familiar with how it's wired or common fault modes.

We're in warranty, but 2000 miles from our dealer. It's getting warm and the shade would be nice.

Any advice is welcome.
