climate control issue

[Y33TREKker]

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".

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.

ok, This climate control issue is still unsolved. I've checked all the relays and and can't find any shorts in the wiring. I even changed the ignition switch and wiring to see if that would solve it and it didn't.
I'm now wondering if the climate control unit is the problem? Anyone know if the auto climate control out of a trooper is the same. From pictures on ebay it looks the same other than the front bezel is different. But , I noticed that that can be removed and I guessing put the one frome the vehicross on to make it work.
Anyone with an ideas it would be a great help.

Thanks in Advance.
