2005 Buick Park Avenue 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.

Intake Manifold Gaskets Can Develop Engine Oil Leaks

The intake manifold gasket may develop external engine oil and/or coolant leak. The intake manifold will need to be removed and the gasket replaced to correct this issue.
