HVAC Actuator

2007 v6 stock. I am having issues with my HCAC Door Actuators. I had the one behind the cluster go bad and the one behind the air bag. I replaced them and everything works excepts for front vents. If i turn it to max AC it blows. When i turn it back it blows defrost. Any ideas what it is?

Did re-calibrate the actuators?

The purpose of the module actuator position calibration is to allow the HVAC module to reinitialize and calibrate the actuator stop points. To carry
out calibration, carry out the following steps.
Remove Smart Junction Box (SJB) fuse 15 for at least one minute.
6. NOTE:
When the ignition switch is switched to the ON position, the HVAC module will initialize and calibrate the actuators. Calibration of the actuators will
take approximately 30 seconds.
Reinstall SJB fuse 15. Turn the ignition switch to the ON position and wait 30 seconds before verifying correct operation.
