05 trailblazer dual climate controls

My 05 trailblazer will blow cool to cold air on the passenger side when I have the ac on but the driver side and rear just blows hot air.

most likely, your drivers side blend door actuator has stopped working. A scanner that can do the hvac system could look at the codes or even see where the door motors are at and see if the doors are moving.

motor #2 is the location for the drivers side blend door actuator (motor)
