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.

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.

GM has recalled 1995-1997 Cadillac Deville, Eldorado, Seville, and Oldsmobile Aurora vehicles because the fuel rail and fuel system return line may crack and leak fuel. In the presence of an ignition source, a fuel leak may result in a fire. Dealers will replace the fuel rail and return line.

GM recalls certain 2002-2003 Cadillac Devillle, Seville, Oldsmobile Aurora, and Pontiac Bonneville vehicles because the fuel tank pressure sensor may fail and cause a fuel leak. In the presence of an ignition source, a fuel leak may result in a fire. Dealers will replace the fuel tank pressure sensor.
