It turns out that your codes are considered PCM codes (not HVAC) in the FSM....

Thank you, but ugh! Still it is good to know that there is something else.

For the record I've noticed that as the cooler weather entered South Florida, the CEL has become intermittent with regard to these codes. Sometimes the CEL will come on, others it will not. It's like the problem is not so prevalent in colder temps. I'm talking sub 75-70F. It was off this morning when it was 65F (I still run the AC). But it came on when it reached 82F.

The A/C must be running to produce the codes.

See if you have a temp sensor on the panel that's under the steering wheel.

Yes, there is a small sensor behind a tiny 'grate' of sorts in that panel. I know that it's there from previous poking. Are you suggesting perhaps check connection? Replace maybe?

Hmm.

Since it seems to depend on the temperature, yes.
