3 window regulators proven defective since owning 2003 Cadillac Deville. #1 drivers window on 9/17/08 done under warranty at 31,000 miles; #2 front passenger window done 11/13/10 @ 52,000 miles cost $356 at dealer; #3 drivers side rear passenger window regulator on 6/8/11 @60,000 milesreplaced-cost $502 contacted Cadillac customer service, received a case # and was told that since car is out of warranty there will be no reimbursement for repair costs. Several customer comments to Cadillac customer service by other owners of similar model and year have same problems and needed replacements of several regulators. Gov't Agency should explore this problem and have Cadillac re-examine reimbursements for repairs of this problem with 2003 and 2004 Cadillac Deville.
