air condition on 2006 Chevrolet Silverado 1500

Truck just started blowing hot air through the driver vents while the cold air blows through passenger vents when the a/c is on. Why?

It sounds like the drivers side temperature door actuator is stuck in the heat position in your 2006 Chevrolet Silverado 1500. This can be confirmed with the use of a scan tool to monitor temperature door actuator position, a faulty code should also be stored in the A/C control module.
Thanks for your help.
