Chevy Impala blend door actuator on driver's side of HVAC dual zone unit
I read so many articles on blend door actuators and they always refer to blend door actuator on passenger side causing clacking noise. But on Dual Zone units there is also an actuator for the driver's side. And to my understanding the whole HVAC unit has to be removed to replace this actuator??? TRUE or False ?? Also if true, what is the part number for 2006 Impala ??
