Is the lock switch in the passenger door on the 2000 SS not supposed to light up or do I have a burned out bulb in the switch.

 

You probably have a burnt blub. However, I think these are LED's are it would probably be eaiser to get a new switch then to replace LED's becasue of how they are installed in the switch. I had this same issue about 2 weeks ago and a couple days before I bought a new switch it came on one day and has been working ever since. You could just have a loose connection
