I spoke with Chrysler about the Window Regulator problem and finally got a straight answer.
All the regulators are bad, its a matter of luck if they stay up.
Chrysler has redone the regulator which now requires the glass to be replaced also. It is a new configuration.
Do not buy just a regulator, and do not let a Stealer sell you just a regulator. If they have make them replace it, it will probably fail.
The new configuration has been available for several months but they have been keeping it quite, in an effort to get rid of the old regulators.
The new process is a "Kit" its a regulator and glass. If you are under warranty run do not walk and get your windows fixed, even if they are not broken. Let your dealer know in writting you are aware of this problem, and give him a chance to correct it. Send your letter registered return reciept.
All the stealers should be aware of this. I went to one and he refused to sell me the old regulator alone, he said you must get the glass. Sorry I didnt write down the price but found a kit on Ebay for 124.95.
If you have problems with the regulator, and you are out of warranty let the dealer know you are prepared to take them to small claims court. Show the reciept for your old regulator and the new and you should win. We should not have to pay for a part that was defective from the start just becuase the Warranty expired.
The number of regulators that have failed far exceeds the law of averages.
You can file a complaint here

Everyone needs to fill out the complaint so a recall can be issued. A window falling down can cause you to become startled and have an accident.
Please tell all the Jeep owners you know having this problem.
Every city has a small claims court process. If your dealer won't cooperate send them a letter (registered return reciept) letting them know your intentions, give them 10 business days to respond then go to your local court house and file your law suit.
