Not familiar with the Volvo, but many cars (Toyota, Lexus, Acura, Honda, etc.) have drain holes at the corners of the sun roof assembly. These holes allow water that gets past the sunroof gasket to drain through tubes that carry the water to the bottom of the car, where it exits the car.

These drain holes are prone to clogging. If the Volvo setup is like those cars mentioned, you can see the front drain holes by opening the sunroof and looking closely at the two front corners of the assembly that holds the sunroof. I have used plastic weedeater line to open up these lines. Compressed air can also be used.

Need more information.....What is the problem...If it is stuck open and you cant close it Check fuses and relay If these are good check switch for power .If all is good The cable is bound or off track....You can close it manually if you slightly remove headliner at front....remove cable from motor and turn the gear in motor with plyers or screwdriver to close it....I have done this with 3 different vehicles....Also if you cant hear the motor you know it is a power problem...But if you can hear the motor and nothing happens the cable is bound or off track.or broke..but that is rare........DONT TRY OVER AND OVER If you hear motor because if it is bound you will burn motor up.!........................
