2004 9-3 SAAB...jumped started and it resulted in no radio and no clicking of signal lights

I had this exact same problem.

The problem was a dead cell in the battery. It had enough juice to turn on the instruments and radio, but not enough to crank over the engine.

If you handy, take the battery out and bring it to your local parts store to be tested. They'll likely find what I described and you'll be able to purchase a new battery and that should resolve the issue.

Sounds like a blown fuse. Start by checking all fuses and replacing as needed.
