Sunroof, Auto Dimming Mirror, Alarm, SRS Airbag
 

I have a 2001 S80 2.9 that I just got and from what I have read online I think I may already know why the sunroof isn't working. I am getting the Auto Dimming mirror replaced b/c there is an orange oval in the middle of my mirror, prolly the auto dimming part gone bad, and I have two messages on my Message Indicator. One says SRS Airbag Urgent, and Alarm System requires service, the Alarm from what I have read obviously needs to be replaced, I have tried to make the siren go off, and the Alarm button on the keys fob works fine, but figured it needed to be replaced, and not sure about the Airbag message. But I am trying to figure out why I can't get the Sunroof to open. The shade opens fine, but when I try to use the switch, nothing happens, and I mean literally nothing, no sound, no movement, nothing. I know it isn't jammed b/c I can push up on the glass and feel everything move. I think it is from the mirror going out, or the Alarm, or a combination of both possibly. If anyone can give me some insight on the subject I would greatly appreciate the help that I could receive.

Thank You in advance!!!
