I went out of town a few weeks ago and when I got home the passenger rear window was down on the Jeep. My first thought was that someone had smashed the window. Luckily that was not the case. It was a classic WJ window regulator failure.
The regulator uses plastic pulleys and stops to hold the wire that runs the window up and down the track. Over time the window track gets sticky and the plastic gets brittle and eventually something fails. This time it was the stop that had broken and the window simply dropped open.
My wife didn't like the repair I made the evening we had gotten home. She said something about garbage bags looking bad, neighborhood redneck, depreciating property values.....soooo. I decided to simply swap the one from my parts Jeep. They are pretty easy to repair and there a ton of videos on you tube. I 'd say the repair could be done in 30-45 minutes if you were swapping new parts.
I found that my 2000 parts Jeep uses a different regulator than my 2002. They look nearly identical but the motor assembly is different. The bolt holes do not line up so I couldn't use the older regulator without some work.
The tape didn't hold. The garbage bag was voted down. More like veto'd!
Removing these two screws is all it takes before popping the press pins.
I started at the bottom using the plastic scraper and a door panel tool.
