At this point, a test light should be enough. What I want to do is start at the fuses. There are two. Since the fuses are new already, I need you to confirm there is power to and from them in the fuse box. A test light is all you will need. Follow this link for testing:
If there is power, then we need to go to the motor/module itself. Power is supplied directly to the module. When you select a setting at the switch, a ground is provided through the switch to complete the circuit.
If you look at pics 1 and 2 below, I attached the entire wiring schematic for this unit. Note the fuses that need to be checked. If they test good, we need to go to the module and confirm there is power at both of the power wires between the fuse and module.
Getting to the motor/module requires the removal of the headliner, so let's move to the switch next. At the switch, there should be power to the blue, yellow, and orange wires (highlighted in pic 3). Use your test light to check for power.
I would like to test for continuity to ground via the black wire, but that will require a multimeter. You should be able to get one nearly anywhere. They are not expensive but don't get one until we determine it's needed.

The last two pics are showing the related fuses for the sunroof. The fuse box is in the luggage compartment. I highlighted fuse locations.
Let me know what you find or if you have other questions.
