Thanks. Mmmm. If I had to pick one I would go knock. Maybe I need to repost. :-). I do have some creaks. Those are clear.

Start tapping with your fist (not too hard on plastic parts) in/around the area you feel its coming from. That's how i've pin pointed creaks/squeaks 99% of the time.Of which i have nearly zero of.

Does it sound like its coming from inside the cabin or out ? Try go with a wrench and sockets and just tightening stuff, or check the door pins. I found mine on my truck were loose, and found a few loose bolts as well!

Did all that. Sounds like it might be under the dash and/or at the firewall. Tightened everything, went for another round of welding. When the car was cold this morning it didn't do it until it warmed up a little.
