Radio/cd player not working, passenger window & power door lock not working 2004 saab 9-3q

Look at the end of the dash and between the drivers side door for a second fuse panel. I think everything you mention works on one data bus. You can remove the button pad on the drivers door. Since it gets used all th3 time i# might have gone bad messing up the works.

Check for a bad switch in the door.
Water leaking from the rag top-door seal joint often drains into the switch, causing a short or bad contact eventually.

CHECK FUSES FOR POWER WINDOW,CHECK FUSE FOR POWER MIRROR AND CHECK FUSE FOR POWER DOOR LOCK.IF FUSE OKAY DOOR CONTROL MODULE FAULTY ITSELF.

check your fuses under dash first

If only the one door lock is not working, the actuator has probally gone bad. An electrical problem may exist, but is not what I would go after first. Check for power and ground signals at the actuator(will have to remove the inner door panel) if you have power and ground, replace the actuator

try cleaning your master switch with air

This is common. Try disconnecting the harness at the door connector (by the door check and hinges) and then reconnecting the connector. Test. Still and issue, disconnect the battery's negative battery connection. If that doesn't do it, you will have to go to a Saab dealership with a Tech II and have them update the software for the Passenger Door Module and re-add the Module in programming.

unfortunately i can only fix the "alternator wine": all you need is a ground loop isolator. it hooks up to your RCA cables in between the radio and amp. the only thing i can think for your other problems is fuses, unless somehow your factory radio controls those functions

Without looking at it how do we know what you did ! Looking at the wiring an view wiring diagrams to see what's up is what would need to be done . Do you know what wiring diagrams are ? Free one's here http://www.bbbind.com/free_tsb.html .
