2005 Pontiac Bonneville ProblemsMode/Temperature Door Actuators May Fail
The mode and temperature door actuators may fail causing improper air flow or temperature output from the heating and AC (HVAC) system.
The engine may develop an oil leak 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.
An ignition coil may fail causing one of the cylinders to misfire. Each of the two banks of cylinders has its own coil assembly. If one ignition coil fails the coil assembly for the corresponding cylinder bank must be replaced.
