AC vent issues

[Uncle EL]

Newb from Phoenix. Inherited an ‘04 Trailblazer LT in really good condition. Except for the fact my AC isn’t blowing through the dash vents. My feet and the windshield are nice and chilly. Hopefully with a lil help and I get to know ol girl a lil better and maybe make some new friends along this journey.

Did you try selecting "vent" - I assume that you did. Can you change the selection at all or is it stuck on defrost? When you try to change the selection, does it make any noises?

Ha. Yeah I played with the buttons. There’s no clicking or anything out of the ordinary. I’ve tried recalibration of the actuators via pulling fuses and placing the key into drive with no relief. I resigned to changing out one of the motors, just not sure which one. Was hoping someone could save me the trouble of trying climb under the dash to watch all the motors actuate and just point me to the one that controls the front facing vents.
