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

Have tried pulling the fuse for various lengths of time, turning off the ac when it gets to the dash position. All to no avail. - Visitor
