Thanks for the quick replies! I messed around with it for a little while yesterday.. I looked down the window hole as you suggested, and, honestly, I don't know what its supposed to look like, but it definately doesn't look like its operating smoothly--then again, I could tell you that from the whole not-being-able-to-unlock-the-door thing..
I pounded on it a little bit, and amazingly, the door opened. Here's where I'm at right now: the key does absolutely nothing in the driver's door now (it just turns back and forth, no resistence, no clicking, nothing--and when I was observing the lock through the window slot, the mechanism that moves when the key is turned does not come into contact with anything else); for a few tries if i held down power lock button in the "unlock" position, I could open the door, that doesn't work anymore though; and, if I pull on the lock hard enough (in the unlock direction) and simultaniously pull the door handle, the door will open. So, now I can at least open it while I'm inside the car, but when I'm outside, it looks like I'll be climbing through the passenger seat.
Either this weekend or next I'll try to get the door panel off so I can take a closer look, I just don't have time at the moment. Thanks for all the help, and if you have any more tips, feel free!
