Seems like my fan blower only wants to blow air thru the floor vents. Cannot get it to the upper vents for either Air thru upper middle or defrost. Any ideas? 1977 w A/C
Also I'm missing the lower A/C ducting on Left (Drivers) side. Anyone have a used one they like to sell?
Thanks!

Could be a bad actuator or a leaky/disconnected hose.

Would that be the Actuator above the right side kick panel?

I think it would be more on the main ductwork under the dash. There's one actuator that controls the flow of air to the different vents.
