2004 Cadillac DeVille ProblemsPower Window Regulators may Fail
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.
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 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.
2004 Cadillac DeVille Questionsrear shock compressor making loud noise while running. cost to replace?? (1 answer)
rear shock compressor making loud noise while running and then shuts off. had an estimate of 900.00 to repair. reasonable??
Acts like a fuel problem by rough running especially up hills. Speed odometer jumps around when it does this has even died twice while going down the road at slow speeds but started right back up. Also rough shifting when this happens.
Sometime it runs great but most of the time seems to be a little rough with more noise than normal. Not a miss just less performance and not smooth or quiet like before ECM went out. Is the 2001 ECM I used the problem? Could it be one or more bad coils? Limited income so I have to fix it myself.
2004 Cadillac DeVille RecallsIgnition Lock Cylinder Concern
Excess weight on the key ring can cause the ignition switch to move out of the run position without warning, turning off the engine. This defect can also affect the safe operation of the airbag system. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring. Dealers will install two 13mm key rings and key insert into the vehicle's ignition keys to correct this concern.
