Possible bad blend door actuator .some gm cars can be relearned to the new climate control head

you have a bad control unit, the thing you use to switch from one thing to the other, it needs to be replaced.

If you have a late model GM car and the system is controlled electronically the blend door actuator becomes weak. When this situation occurs it will not move the air direction door inside of the heater/air conditioner plenum. in your case not to the vents Replace the actuator with new and recheck the system. i hope this helps

It will not be a fuse,the actuator motor is bad,the fuse is tied in with the blower and such,if the blower is working ,then the fuse is good.
