Hi,
The first thing we need to check are the fuses. There are two fuses located in the body control module which tie into the sunroom. If you look at pic 1 below, it shows the location of the body control module. In pic 2, I highlighted the two fuses I need you to check.
In addition to checking the fuse condition, I need you to confirm there is power both to the fuse and from it. Here is a link you may find helpful:

Let me know what you find or if you have other questions.
Take care,
Joe
