Anyone got any ideas on this electrical problem

[iroc22]

k on the weekend I used the defroster and now whatever selection I choose on the HVAC all the air does is blow through the defrost vents...doesnt matter what I have selected...A/C still works but blows only through defroster vents..
I checked the fuses and they seem all ok and this same problem happened to me in my Jeep and it turned out one of the plugs going to the vent selector was bumped off, but I have no idea where the vent selector things are in these cars...

please help

nevermind figured it out, the vaccum routing for the actuators goes through the defroster/floor duct actuator (via a green/yellow vaccum line) first and no vaccum was getting through it.
