Just bought a 98 gtp and can't figure out what's wrong with it

I will make sure all the drivers side is good also.

What problems all happen with the ignition switch going bad?

All kinds of things. Most commonly is no HVAC and no auto on lights. You can replace the ignition switch, or do this "ignition saver mod":

Here's schematics on the fuse panels; they are for 2002, but should be the same for 98:

I will definitely give that mod a good look to see if I should do that. And thank you for the schematics also.

No problem. I bought a new ignition switch a few years ago, with the plans of changing it. When I did, I found that all my aftermarket alarm wiring was tapped into the switch wiring, so I changed plans and just did the mod. Been almost 3 years and it is working just fine, so it is a viable option.
