Hello everyone, and thank you for any and all help.

I am struggling to identify and order the correct heater actuator for my 2004 Silverado with dual climate control. I need the actuator that is on the drivers side on the vehicle, common to the cam plate. I have looked at both GMpartsdirect & GMpartsgiant and get conflicting part numbers.

I ordered one actuator and cam assembly once already and later found out it was the incorrect actuator. This actuator isn't by any means the most difficult of the actuator to replace, but the constant clicking it makes when my heater is set to certain positions is now became more than I can handle.

 

Remove the broken actuator and get the part number off of it. This link may also help.
