Welcome to MVS.
You changed the thermostat and still nothing, huh?
I would be willing to bet that the problem all along is the ECT sensor- it's the engine coolant temp. sensor that resides at the base of the thermostat housing- these go bad and all kinds of crazy things begin to happen along with the fan not coming on. Good luck and let us know if that was it.
