OK, I admit I am an idiot. I can't remember the proper names for some of this stuff, which really hurt my attempt at searching.
I need to try the WD40 fix, but while looking at the passenger side door "claw" assembly that clamps on to the part on the post to hold the door shut, I saw a small spring that was obviously disconnected at one end, can't see the other.
Any ideas on what this is and could it be causing the door ajar light to stay on? I know it is the passenger door since it doesn't cause a ding when opened with the key on. The door latch seems to work better than the driver's side, and no known issues with it locking or unlocking.
Thanks,
Russ
