2000 Cadillac DeVille Problems

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.

2000 Cadillac DeVille Recalls

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.

Cadillac has recalled 2000-2002 DeVille vehicles because the seat belt retractors may not lock as required when in an accident. This increases the risk of injury to vehicle occupants. Dealers will install a retainer kit to the safety belt pretensioners.

Cadillac has recalled 2000-2001 DeVille vehicles because the seat belt buckles may require too much effort to release. This may delay exiting the vehicle in the event of a crash. Dealers will inspect the belts, modify latch plates, and replace the affected retractor if necessary. Dealers will also add "snap on" latch clips to ensure proper insertion of the buckles.

air only flows in defrost mode. How do I replace the air flow actuator?

The Deville is a great car when it runs! Problem areas center around overheating, oil leaks, and ignition system faults. Overheating can be a real issue leading to blown headgaskets. Many of my friends have traded their Devilles in whe the problems get out of hand.
