The problem that I had was that the driver's side vents were not blowing cold air while the passenger side was cold. In the majority of cases the problem is low freon. (Check TBS on video). In other cases can be the air blend actuator stuck or not working. Video show how to test the air actuator, if it does work, then the next step is to get the AC service.
