2003 Cadillac DeVille DTS 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.
The engine may develop an oil leak 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.
The steering wheel position sensor may fail, resulting in the service stability message being displayed.
