Ac stuck on top/defrost vents

[Jr1030]

Hello! I have a 2000 Silverado that only blows from the top vents. I try to change it to the front and it’ll either blow very lightly from the front vents and continue to push from the defrost area or it just stays on defrost, my question is what am I needing to replace to fix this? I keep getting different answers about which Actuator it is & I keep getting told it’s under my steering wheel than I get told it’s under my passenger dash. I understand there’s 2-3 different ones I’m just needing to know which one exactly and where it’s at, as well as any other info someone may have! Thank you.
