I checked them against my 99 vehicross and only one is powered on eb-25 and none are powered on eb-27 with the key off. I made a diagram to show which are hot with the key off by marking them in "red".

Did you check with a voltmeter that the EB-27 (Starter Cut) relay showed proper continuities when you had it removed?

It should show continuity between pins 2 & 4 (the internal coil), and continuity between pins 1 & 5 when pins 2 & 4 (Normally Open switch) are energized with battery 12 volts. If continuity between pins 1 & 5 is present at all times, the relay is stuck or shorted (which would be keeping the Heater A/C relay energized at all times and applying power to your Auto A/C controls).
I did not. But, I will tomorrow. I hope that is it. thanks again.
