Will keep an eye on it - but now AC compressor doesn't turn on

Alert me when someone posts in this thread:

I cleaned up the terminal real well, hoping that it was just some corrosion causing the problem. I'll check it periodically to see if it is getting too hot.

Though now another problem - the blower is working but the AC compressor is not turning on! The never-ending story...

Checking here on the board, so far I've found a post saying that there needs to be a signal that the blower is running for the AC compressor to engage. That was for a base 9000 with manual AC but it sounds reasonable that the ACC system would behave the same way.

Since the AC was working fine before I started monkeying with that connector I'll have to double-check that the wiring is OK there. Maybe the small wires on the connector provide the AC signal? Looking at the wiring diagram the small blue and green wires go into the ACC unit. Maybe I accidentally reversed the wires or one broke internally, they're pretty small. (I can check the wire positioning against my other 9000.)
