so the rear running lights and dash lights are not working

Have mechanic replace failed fuse!

CK PWR TO SOCKETS, I GUESS YOU HAVE ALREADY CK'D BULBS

I had the same issue with my 2001 lw200 I ended up having to create a new fuse wired to a switch that I installed otherwise the saturn mechanic said the cost would kill my bank account to fix. Saturns are nothing post electrical nightmares the mechanic said

I don't know if this helps, but I did find a recall on the rear lights. Anything you can't seem to explain Saturn does stand behind their cars. They do have three recalls.
