I replaced the fuse for the moonroof because it wouldn't open. That didn't fix the issue. Any ideas how to troubleshoot this issue further?

The system is pretty basic, but there are two fuses that run the system I would double check, fuse # 35 and fuse #66 in the under-hood fuse panel. Here is a guide to help you check them and to see if they are getting power:

Here are the wiring diagrams so you can see how the system works. The motor is contained in the module so if the fuses are good the switch or module is probably to blame. This wiring diagram shows the system and I have included how to change the module out, please check it for power and ground first.

Check out the images (below). Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.
