1998 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.
