So now I will never roll my windows down again I have tape over the buttons so that no one will use them.
Tl contact owns a 2004 Cadillac Deville. On August 22, 2008, the contact inserted the key into the ignition and the air bags suddenly deployed. The deployment made a loud bang that startled him and his wife. The police and fire departments arrived and filed a report. The contact's wife sustained bruises on her body and face. The contact had the vehicle towed to the dealer for repair. Since the repair, all of the other warning lights are illuminated on the instrument panel. His wife is scared to drive the vehicle. They spoke with the Cadillac manufacturer, but they did not seem to care and offered no assistance. The vehicle was parked overnight in the contact's garage. The failure mileage was 21,743. Updated 10/14/08 the rear driver window was inoperative. Updated 10/15/08.
Tl* the contact owns a 2004 Cadillac Deville. The contact stated that the front passenger and driver side windows experienced a failure in which the glass fell down into the door panel. The vehicle was taken to the dealer who advised that the window regulators would need replacing. There were no recalls and the repairs of over $1,000 would be at the owner's expense. The contact then took the vehicle to a local mechanic who replaced all three windows. The manufacturer was notified of the failure who advised that if he had taken the vehicle to be repaired at the dealer they more than likely would have assisted with the cost of repairs.

I have experienced two power window failures on my 2004 Deville within a one month period while driving. Windows fell into the doors, front and back, and would not raise. Both failures were on a car with 55 thousand miles on it. Dealer repaired it at the cost of $686.00. Contacted Cadillac customer service with them refusing to admit there is a problem and unwilling to offer any compensation toward the repairs. I am waiting for the other two to fail. Relative has a 2003 Deville and has had three windows repaired already. I feel that this is a safety issue and a recall is in order, now!
April 2007 right passenger power window went out. May 2007 right rear window. Power window went out. December 2007 driver side power window has gone out. Dealer has not offered any help or compensation. They gave me the phone number for their customer service headquarters. I called, they were nice and promised to speak to the dealer. It seems the dealer has not responded to the calls from customer service. Now, customer service hasn't returned my call. I'm waiting for the fourth and final power window to go bad any minute.
Right front window dropped/broke down causing a $500 repair. Three months latter the left rear window also broke causing another $500 repair. Now, in 2014 the right rear window has broken, while driving on the freeway, startling my wife and grandchild with another very loud bang! This is a continuing problem on a car that only has 48,500 miles on it, and is always parked inside a garage. There are way too many reports of this happening for the feds or GM not to do something about this failure!
All the windows have fallen down one time or another in the past 6 months! On june28th 2011 I replaced the front passenger regulator. Just to have it fail again under four months. I only used the window three times! I have read all the complaints from other owners of this year of Cadillac power window problems and their should be a recall! This is the worst car I have ever owned. It is a hunk of junk!!! This latest regulator problem happened two hours ago! October 23rd 2011.
