Did you check with a voltmeter that the EB-27 (Starter Cut) relay showed proper continuities when you had it removed?Originally Posted by maxprime
Is there another relay between the rt fender power block and the control module that could be bad and powering it? If I pull the relay on the power block. It shuts havc controls off.
I checked the fuse box behind the battery and tested the relay connectors and found 2 are constant power on relay eb 25 and the center one is powered on eb 27 without the key on. 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".
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).
