I pull of the connector to the ECT. The fan comes on then. It aslo doesn't come on when I turn the A/C on either. The A/C may be low and not allowing the clutch to engage and I bled the cooling system. I just put in a new radiator and don't want to risk loosing the HG cause of this. Any ideas of where to look for repairs. And I would rather not cut wires or add after market controllers to the car just yet.
