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.

Purchased quite used in December of 2013. This Fleetwood had 84,000 miles after twenty years! The ride cannot be beat. The mileage is excellent (24MPG) and the power (160 HP) is phenominal. I said many years ago that I'd not ever drive an ugly car. This is the car of my dreams. When something on it needs attention, I don't mind putting the money into it....it's worth it!
