this one is easy your switch the controls the vents is not working there is a flap the closes the defrost vents so that it goes through the other vents or there is a vacumn line that is controlled by the switch, and its leaking.

If the a/c compressor cools the air coming from the vents, and the heater knob makes the air hot, but the fan switch doesn't change the speed of the air coming from the vents, most likely the culprit is the fan switch itself, the blower resistor, or the blower motor.

The vents are opened and closed by vacuum. There should be a vacuum line running from the engine to the inside of the Trailblazer. That line is broken somewhere and it is not sending vacuum to the switch. That will cause it to blow to the top of the dash (defroster) and to the bottom (floor.) Find that line trace it back and splice a new line in where it is broken. That should fix…
