: 04 CTS-V sunroof doesn't work

I have a 2004 CTS-V with a nonfunctional sunroof. It doesn't do anything. I tried doing the reset procedure but that didn't make it it work. When I turn the dial to different positions I hear a faint click that sounds like a mechanical relay. Is my motor toast or is there something else I can check?

Thanks, that doesn't really help though without pinouts and part locations. Does a relay normally operate if the switch is bad? I'd imagine it wouldn't.

There is a fuse/relay in the right rear fuse block. There is also a switch and a module. See attached. (I do not have a sunroof, so I have no direct experience on this.)

Fuse is good, when I removed it, the relay wasn't clicking with the switch. Must be something else. Guess I'll be taking down the headliner.

You wouldn't happen to have the procedure to lower the headliner would you?
