Volvo Repair: 2000 s80 volvo electrical problems, volvo vadis, s80 volvo

Question
no ac, no fan, no heated seats. all accessory switches are in-operable. fuses all seem to be good

Answer
Lee, anything S80 related has to be hooked up to the Volvo Vadis computer system.  There is no way to tell whats wrong without have the computer read the codes.  It could be a number of things.  One of the modules has gone bad.
I suggest the dealer or Volvo shop who has the proper equipment.  The S80 is totally Computer controlled.  Sorry for the bad news.  Roger
