Grinding sunroof while opening

I have a 1999 volvo s80. I heard grinding from sunroof while opening it; so I went ahead and looked into it by removing the ceiling lights and exposing the mechanism. I saw that it was a tad out of place or stripped along the spiral lining that goes around the sunroof. Next I unscrewed the motor mechanism that connects to the sunroof. When I was handling the unit (gently); the radio I was listening to started to go in and out. I had not unplugged the unit yet. I was baffled n confused because I had not touched wiring yet. To make matter worse, I unplugged the sunroof unit from the small black unit; so I could take it out to look at it. Then after I put it back in, the car lost all its dashboards lights and the radio. Even with the key in and to the on position, I got nothing at all? With key on I heard a clicking sound from under dash in relay compartment. I felt the relay that was clicking; it was the fog light relays. What possibly could have happened here? I checked all fuses in the side panel inside the car. They are all good. What could I check next? Is it possible I blew a fuse from the engine compartment that controls the inside fuses? I just dont know what to do. Sigh. I really hope nothing serious happened. The car is a nice car. It had no issues:(( magneto774
