The rear ax blows cold but the front blows warm tried the actuator and that didn’t work not the blower motor either what else can cause this issue.

I think you got the wrong actuator or the front HAVC controller is bad, lets try this, here is the location of the temperature blend door actuators one for the passenger and one for the drivers side. I would remove it then start the engine and turn the A/C on full cold, low fan speed, then work the blend door pivot to see if it gets cold. Let me know what happens.

Scroll down, you will see the locations.
