Thanks, I couldn't see the magic smoke peering at the wiring schematic.

It really is ridiculous what they have done with the A/C programming. They even try to use the day/night sensor in the top of the dash (that tiny little black dot looking sensor thing that every driver seems to cover over with their log-book or these days,.. bag of cheeto's,.. right above the steering-wheel, -- that thing is for detecting "fog conditions" and all sorts of other over-bearing horse-s$it in that cab controller.
