1998 Cadillac DeVille Problems

Heating and AC Temperature and Air Delivery Mode Door Actuators May Fail

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.

Fuel Level Sensor Failure

It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.

Power 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.
