“Let me guess... One of the rear windows in your Jeep Liberty just made a snapping or grinding noise, the window no longer works, the glass wants to fall down into the door and you can move it up and down by hand? If so, then please allow me to be the first to welcome you to the club!”
The power windows in the Jeep Liberty are notorious for breaking in this manner. The problem is the design of the mechanism used to move the window. The Liberty uses a plastic window bracket that rides inside of a metal track in the door. As you use the window, the part of the plastic bracket that rides inside the metal guide rail tends to wear away until it becomes too thin to support the weight of the window, at which point it snaps and down comes the glass! Wear isn't the only reason for the failure of this part however - it is simply too weak. I know people who have had brand new window regulators installed and despite never using the window, the regulator broke anyway. (This happened to me just yesterday)! I'll bet you a jillion that the part is made in China!
A kit, made by a company called Steiger, which will supposedly fix the problem and is available here. Installation instructions are here! A word of caution. This fix has not been vetted by anyone I know. If you have used it and it works, please share in a comment. Likewise, if you have experienced a similar problem, please leave a comment. Thanks! Be sure to follow my exploits at attempting to fix this problem here.
