Air stuck to panel vent

[Fatass]

Read tons here. Just posting

Unlike many threads, my air and heat work fine. Only issue is in front. whether a/c or heat, only air comes out panel vents. Nothing too defrost, nothing to floor.

So is this still an actuator issue? if so which one?

Rear works fine, the 2 buttons for recirculating air / fresh air light up shortly then go out.

So replace the control unit? or if actuator, which one?

thanks

I would like to know this as well. Mine is stuck on defrost, but guessing the fix is the same as yours....maybe????

it's still a blend door actuator problem. but instead of blending heat or AC, it's the different outputs (floor,upper vents, defroster)
