One or more of the power window regulators (one in each door) may fail causing the window to fall into the door and not roll up.

2004 Cadillac DeVille Problems
The engine may develop oil leaks from the lower crankcase portion of the engine block. Our technicians tell us that the engine must be removed from the vehicle to properly repair this oil leak.
One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.
The torque converter clutch (TTC) may stop working due to an internal transmission failure. The Check Engine Light will illuminate if this occurs. Our technicians tell us the transmission will require dis-assembly to correct this concern.
The crankshaft position sensor may fail causing the engine to stall intermittently, the Check Engine Light may or may not illuminate.

2004 Cadillac DeVille Reviews
Its a great car mechanically. But is has too many sensors and monitors that with time are going to malfunction. I have a 2004 cadillac deville. 190,000 miles. Im having trouble with old wiring and areas being monitored that still work but are old . Setting off codes like crazy and difficult to clear. I still get 19 miles city and 24 miles highway. Mechanically it rides great.im now changing a tps sensor connector. Im getting a code telling me insufficient voltage. Its off by .5volts and im going nuts with this .5 voltage problem. This is age not a problem with the cars running well.So its a pain in the arse so to speak later on. I didnt like changing the head gaskets with 50,000 miles on it. Very expensive etc.Electric switches on steering wheel lighted burn out, still work but they dont light. little bs things that shouldnt happen with this car.Not for the money u spend. If you still keep this car change the oil and filter every 3000 miles. let it drain well. it will run forever.
ILL FIX WHAT EVER I FREAKING LOVE THIS CAR plus every car will break down or another if it is not maintained or tuned. Ppl take good care of ur cars and they will take care of u
Transmission problems are common and very expensive to fix. The price of a transmission replacement just about totals the car. AC system and PS pump have had to be replaced. No oil leaks, no engine failure thus far at 93k miles. Center console/body trim has several weak spots, specifically the center console is broken. Brakes get this big car to stop very well.
Wow . . after reading all these negative reports I am so pleased to add mine to the positive ones [if there are any here]. We purchased our Deville new in late 2004. It currently has 184,000 miles on it. It's service to me has been incredible. Brakes once, torgue converter replaced once, a windshield wiper motor replaced. No other car I've owned in 50 years has given us better service with so little repairs. What else can I say?
I brought this DeVille (2004) used in 2006 with 56,000 mi on it.
This was my first Caddy, however it will be my last. The main thing is the replacement of the window regulators,the dealer soaks you for $550 to replace them,what a racket. I had 3 fail on the car,but had the other two replaced by Prep Boys saving $550.I now have 116,000 miles on it. The car leaks inside on really rainy days there is water in the sun roof panel, the knee bolster came off while I was driving,the screws came out of the center console. The a/c makes loud noises,plus the front suspension is quirky over bumps,yes if the road is flat and smooth the car rides great.Also the front left inner rim were rusting causing low tire pressure,so the fix was to put a sealant around the rim to fix the problem. Nexy car will be a lexus. I want to buy American,however the quality of the Caddy brand is terrible.
