When AC on and cold air from rear but not front is usually a blend door/heater box issue. You may have a non functioning blend door motor that controls hot/cold distribution of airflow
Just got an answer from Chevy Dealer. When you replaced the battery it loses its memory as to where the door actuators were (the flaps that control the heat and A/C).
The fix: Turn everything off and let the car sit overnight. The computer should reset itself during its learnings process. In the morning turn on the ignition and let the car run for a few minutes before turning on the climate control.
If this doesn't work, plan on 1-1.5hours of labor for a technician to reset the actuators at the dealership.
This is something best done by a qualified repair shop . An yes it can have two different problems , not related ! Blower motors do go bad , or a control processor . Does it have manual or automatic HVAC . It would be to your benefit to have someone like this guy diagnose the problem . This is not for a rookie to try ! Diagnosing rear problems
