Question about 2006 Nissan Armada
When I switch the ac/heat ducts from any other position into the face position for the vent air flow there's a very audible knocking sound. I need to trouble shoot myself as the warranty is used up 3/36 . Do you think something dropped down into the duct and is blocking the mechanisms or is it a broken part issue?
There is a very small black hose that provides vacuum to operate the different vacuum motors in the system through the switch you mentioned, that switch simply diverts vacuum to what ever air outlet u select, the vacuum comes from the engine, it goes through the firewall on tha passenger side, like I said it is a small black hose.

first be sure temp control is pushed over to cold. If the system is still there, you need to add refrigerant to system & check for leaks
