2000 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.
Vehicles equipped with the 4.6L engine may develop excessive oil consumption. Please be advised that under optimum driving conditions, using one quart of oil every 2000 miles is acceptable. This Cadillac standard applies to vehicles with less that 50,000 miles. Our technicians tell us that if you experience excessive oil consumption it may be caused by built up on the piston rings which restricts movement, preventing them from wiping all the oil from the cylinder walls. Oil left behind is then burned during the combustion process. There is a special ring cleaning procedure which can help this situation. The GM service bulletin number is #02-06-01-009C.
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.

But low battery light is coming on.
Alternator trouble? I may have to replace the battery also, correct?
AC won't work. When I turn it on it just blows out hot air. Last time it worked was last summer. I can't take it anymore. Tried coolant and it would even register
2000 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.
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.
