Chevrolet Silverado 2500 Improper HVAC Temperature and/or Air Delivery Due to Failed Mode Door Actuator

(21 reports)

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.

The problem is that the air only blos out the defrost and will not change over to any other outlets. I am having trouble finding the delivery door actuator for this, but have foound the temperature control one and it is working fine, so far. Any help on finding this thing would be appreciated -
Upon starting the truck, the mode door seems to cycle from floor to dash to defrost and stays at defrost regardless of switch position. Started IMMEDIATELY after replacing blower moron resistor.
