Volvo Repair: Volvo, sunroof, vanity lights and power door locks dont work, volvo s80, 2001 volvo s80

Question
I have a 2001 Volvo S80. A few weeks ago the sunroof would not close, the light for the vanity mirrors in the back of the sun visors  and the power door locks would not work. I checked all the fuses. The all seemed fine and after removing and reinserting the fuses, everything started to work. I ran into the same problem this morning. This time no matter what I did, I took out and replaced all the fuses that were inside the passenger area, the sunroof would not move, the vanity lights did not work and the power door locks did not work. I checked the sideview mirrors and they work fine. Any hints.

Answer
You need to bring the car in and have the system scanned.
I never said you had to bring into a dealer.Many independent shops have the ability to scan Volvos. I don't care what your opinion is,you asked for mine. So for giving me a 5 in knowlege, I'll give you a 1 as a customer.
Listen to people instead of jumping to conclusions!
