Yesterday I went to bring my power window on my driver's door up and it clunked and went all the way down. I looked at it afdter rremoving the door panel and there looks like a half circle plastic piece where the cable runs on was laying on the bottom of the door. The motor was fine, it looks like maybe just that plastic piece broke........... any ideas?

That sucks, which Jeep do you have? It's not listed, and you didn't say.
The plastic cable anchor in the window regulator broke recently, so I checked around for repair options. AutoZone offers the regulator w/the motor for $99, or wo/the motor for $50, w/a lifetime warranty.
I found this place that has just the anchor, made from aluminum, for $29.95. http://pocketlogger.com/?pid=jpw
I needed it fixed that day, so I opted to get the complete assy. from AZ.
