Volvo Repair: Nothing works, rear headrests, moon roof

Question
2000 s80 2.9, everything below the stereo doesn't work ( a/c, seat heater, the orange light for the gear select, the light for the "W" switch, the buttin that drops the rear headrests, the button that unlocks the trunk, the dome lights that are button operated and the moon roof) i checked all the fuses and non of them are blow is there anybody on here that could help me out?

Answer
Daniel, the nightmares of an S80 suck dont they? Thats why I tell people to get rid of these electrical nightmare cars.  Believe it or not, the problem is most likely in the alarm module.  (Dont ask why, it just is)  This needs to be taken to a Volvo shop with the proper equipment because Im pretty sure the new module will need a download.  Sorry about the bad news.  Roger
