I removed the three knobs at the top of the MCC and then removed the two screws under the right and left temp knobs. The control came out about two inches and no further. I then removed the radio and the MCC came out. I unplugged the two connectors at the back several times,
first just to remove it and then to determine which was related to the fan and which to the heat/AC. After at least two disconnect/reconnect cycles, I think it was three, the AC/recirc lights came back on and the A/C kicked in. Go figure. I can only assume it was oxidation on one or more pins in the connector, that got scraped clean by repeated connection/disconnection. My favorite type of repair - Free!

Thanks so much for pointing me to the Climate Control module.
