The sunroof circuit for my 2014 Equinox is pretty simple.
Yours should be similar.
Battery voltage goes thru the #12 fuse in the under hood fuse block, thru the two switches, and on to the motor/controller/module.
See if you are getting voltage at the switches, key on.
Or go to the motor first and push the switches to see if you are getting power which ever is easier.
The sunroof circuit can set a DTC in the BCM to help in diagnosis.
Don't forget to check your grounds
