Bought a '14 Caravan cheap as it had a couple small issues . One issue that needed addressed was an air door actuator. It would ratchet for about a minute, goes dormant like you shut it off, then the system would work. It had been replaced previous and not soon afterwards it acted up again.
Now, with a new ADA, it no longer ratchets, but now I have to "cycle" the dual temp selectors back and forth ( it'll blow heat on the driver's side ) in unison to get them in sync I guess. After that, it's fine. 8 times out of 10 I have to do that.

Mechanic says he's researched a fix, but can't find one. Anyone ever have this happen after "fixing" it? I have learned I can do just the drivers' side one and get by with it.
