My buddy has a twin truck to mine. 15 CC SV. Horrible noise behind the dash confirmed to be a bad actuator. I was able to scan it while it happens and can see that the "Passenger Mix Feedback" is stuck around 4.3 (open). What I can't tell, is which actuator is the problem. This is the diagram from Nissan. I think it's the top actuator, but its echoing through the whole housing so it's hard to say. It looks like it's going to be a pain regardless... If someone can confirm which actuator is the passenger mix/temp control and where it is on this diagram - it would be greatly appreciated.
