After starting the 09 Impala yesterday morning a popping noise started from under the dash behind the Radio. It sounds like a plastic fan blade hitting something.

It starts and stops randomly and continues weither the heater fan or the radio are on or off.
Thanks in advance, Henry.

It is the DR side heater door motor.

yup actuator. Extremely common issue.
There is 2 of them if it has dual zone, at least for the blend door. Not including the mode door actuators.
But if yours is right behind the radio it is the drivers side blend door actuator

Old School GM fan FOREVER
