ACC compressor not engaging, ACC relay??

Hello everyone:
1996 900 SET 172K.
My ACC stopped working recently. Whether you press AUTO or ECON has little effect on the compressor. It does not engage.
If I remove the ACC relay from the engine compartment and "hot wire" the compressor feeds 30 bad 87 on the relay the compressor works fine. This would suggest it is the relay, except I replaced the relay and it still does not work!?
What am I missing? Could the problem be some other component upstream of the relay circuit? I checked the fuses and they are fine.
Thus far I ruled out:
1. Fuses
2. Compressor
3. Refrigerant
4. Relay (the relay itself not the circuitry)
