Alternator/generator/regulator problems of the 2002 Jeep Laredo

For no specific reason the windows on the Jeep cherokee grand Laredo suddenly drop in their channels and will not come back up. I had a similar failure on a 2000 model previously owned, and now with my 2002 I had the same issue on December 31 2005 with the rear driver side window, and yesterday with the passenger front window. This morning I called Jeep customer service and was given the typical runaround. I have extended warranty and tried to get the deductible ($100 per occurrence) waived and that didn't work either. I was informed by my servicing deal that this is a known issue that was supposed to have been corrected in models starting in 2005 where they switched the plastic regulator for a metal one. I informed customer relations that this is not an isolated issue as two other coworkers have had the same issue on three windows in the same model trucks/year. Who knows how many others there are out there!. Daimler Chrysler obviously doesn't realize that this is a very dangerous situation than can expose drivers to accidents while driving if they have to pay attention to a sudden dropping window, or a potential personal safety issue if driving in a potentially dangerous area. Please investigate what can be done about it.
