That's controlled by something called an "Intelligent Power distribution Module" which is controlled by the ECM after referencing the coolant temp sensor. There are (2) 40 amp fuses to check also.

I've checked the fuses, and all 3 fan relays check good. The coolant temp sensor was replaced, so its new. I'm kinda stuck, don't know anything about these japanese cars.

Will any fans come on with the A/C?

The only fan that comes on with the a/c is the blower. I bypassed the fan relays and can make both fans come on. However the relays check good. I've got good voltage to the coil side of all three relays, however there is no ground. Im guess ing this is how the ECM controls fan speed, by switching the ground? I'm so lost, LOL

Yes, the ground is the control trigger. You have no way to test that module though.
