1998 Buick LeSabre Problems

Improper HVAC Temperature and/or Air Delivery Due to Failed Mode Door Actuator

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.

Engine Stalling Due to Mass Air Flow/Crankshaft Position Sensor Failure

The mass air flow or crankshaft position sensor may fail causing the engine to stall intermittently. Proper diagnoses will be necessary to determine the cause of any stalling condition.

Erratic Shifting of the Automatic Transmission

The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.
