Re 2] Reservoir out port to ACC controller. You must remove passenger airbag to access it. Easy DIY, but get specific instructions elsewhere in forum.

"Diverter Air Flap" pod located above center vents is probably not working properly allowing warm outside air to mix with cold AC.
Pull the pass air bag and test controller's #6 [2nd from bottom] for Diverter Air Flap.
Bob, thanks!

The Reservoir out port is open at the bottom. I can see hard plastic vacuum tubing that is not plugged -- is that the normal state?

Would the diverter air flap pod account for the irregularly oscillating hissing I hear?

I will test the controller tomorrow, pulling the air bag per these instructions I found searching threads yesterday:

1) Disconnect the negative battery cable
2) Pull up the front carpet under the passenger's feet
3) Remove the 1 screw holding the plastic or metal shield in place
4) Unplug the big red connector (this is for the airbag system)
5) Unscrew the one long bolt that holds the airbag in place (bottom/center)
6) Pull airbag forward, unplug connector
7) Installation is the reverse of removal.

To do the test, I assume I'll need a MityVac?
