1999 C1500 5.7L Chevy Suburban Recirculate Actuator

[shultzee13]

Replaced the Recirculate actuator today but still not working. Brand new control unit and I performed the "reboot" of the system as instructed on here.
Is this controlled by vacuum or power? Whichever what are the parts needed to replace? Is this a vacuum pump or fuse?

Both mode and blend door working correctly.

Last question….would this have anything to do with the AC not blowing cold in the front?

Thank you guys in advance. HOT in Texas.
