The sunroof issue you could have had is that either one of the sunshade clips broke off or the vanity curtains separated and cause the sunroff to jump out of place? As far as the other stuff, you could have had set that off by accident? Disconnect the battery cables and touch them together for at least 5 minutes. That should reset the whole network. As for the sunroof, it may be too late now. You will need the sunroof cable guides replaced ifc it jumped out of track. Inspect the motor gear for damage as well and replace if necessary. And replace the vanity curtains and sunshade clips.
Set what off? I have no power to the car in 1,2 or 3rd position. wont turn over. with key on to 2nd position i just hear the fog relay clicking. Let me clarify;take the positive and negative terminal off the battery and hold the 2 together for 5 minutes? does that basically discharge all current running? doesnt removing negative cable alone do that?(no ground for current to travel to)..
To do a battery reset yes, you need to disconnect both battery cables and touch them. The networking on this vehicles is very complicated. By touching the cables together you could say it drains any reserve juice it may be storing so just simply disconnecting the ground cable will not reset anything. Once you touch the 2 cables together while disconnected it is like doing a computer reboot. If that does not work call Volvo to see if they are participating in the Volvo service for life program? Here is the link for more info.

What you should get is at least a free scan of the network to see if maybe the network has crashed? If there is an issue with both the High and Low speed CANBus then the Central Electronic Module could have just failed? But you may need to pay some diagnostic time to get in that deep? But try the battery reset first and let me know what happens?
