The same thing happened to me. It is a control rod; links the outside handle to the lock (actuator). Most likely, the plastic clip that holds the rod to the handle broke; which free's the rod to get in the way of the window when it's going down. Hopefully it did not get to bent out of shape (no pun.) Although it is time consuming; (mostly to be safe), it is not difficult. A good ratchet set with a univeral is all you need.
I was able to gently bend the rod back it to place (without breaking it) and put a new clip on. I found one at autozone or something. Came in a "Foreign car door rod clip multi-pack." Or you can go for it and go to the dealer and get the oem.
Thanks to all of you who responded, it helps alot, I LOVE THESE FORUMS!!!!!!!!
