Based on if this has automatic climate control or manual control determines the locations of the blend door actuator (air mix door). The air mix door actuator is what controls the temperature entering the vehicle.
I attached a pic below of the manual system and indicated the air mix door actuator for you to see.
Here is what I need to know. First, you indicated you have heat. What happens when you change the setting from heat to cool (even with the AC off)? Also, I need to know if you have automatic ac or manual. If it is automatic, let me know if you are experiencing this on both the left and right sides of the interior since it will have dual climate control.
See pic below.
