We have a 2002 Jeep Liberty and have had to replace 8 regulators, 6 under warranty and 2 after warranty. The Driver Side regulator broke again yesterday. I read online that the block at this link (http://www.pocketlogger.com/?pid=jpw
) will work but haven't tried it yet.
In the interest of "word of mouth advertising" if you live in the Phoenix area, never use Power Jeep (or probably any other publicly traded auto dealership). Their customer service creed and mission statement seems to be "the Power Way or the Highway". After physically damaging our vehicle, they would not step up to make it right as well as them losing parts and not replacing them.
Just replaced the front driver's window regulator. Listed for $265, dealer gave it to me for $225, $245 out the door. (Performance Jeep in Glendale Arizona)
It took about 35 minutes to remove and replace. If you have tinted (film) windows, be sure to secure the glass all the way up so you don't knick the tint film while working the regulator into the door. I used filament packaging tape. Taped one side of the glass up an over the door with the role and taped the other side of the glass. The tape holds pretty good an only needs one strip (less adhesive to remove from your door if it is hot out).
The front regulator is different from the rear and the blocks referenced earlier probably won't work. The cable is actually what was broken.
To remove and replace, all I needed was a Philips head screw driver, #1 flat screw driver (for clips) and a 10mm socket (power driver makes the job go faster).
The door panels come off pretty easily (no fancy clips).
