2000 Saab 9-5 help........

first thing first let's do a electrical test locate fuse for one of the components that is inop ,remove fuse now turn ignition on take a test light and check if power is on one side of where u pull fuse ,if not move to next inop component do the same ,if no power then your problem is with the body control module [or dice unit as saab call it ]located under dash at d/s above relay box while there check if u see any burn wiring u may have a shorted wiring problem if it is not the control unit ,but all these inop component r controled through DICE UNIT .good luck
