The way these solenoids work is that a low current actuation (from the ECU) closes a high current circuit (in this case the fan). If you applied 12v back to the ECU lead that would be enough to cause major damage. All it takes is momentary contact to sorry out a circuit. FWIW I have blown plenty of fuses like this, I have certainly learned this lesson the hard way.

In my mind I would have a hard time explaining so many problems that simultaneously started with anything but an ecu short.

Unless this car is a 2000, a swap from your S will not work. The ECU must match the ME version that is currently running in the car, and that changed from 7.2 to 7.8 in 2001 or 2002, in don't remember off the top of my head (I think 01 cars were wired with can bus systems but the change to 7.8 didn't happen until 02)

What I would do is call a reputable company that works on ecu's and describe the situation to them. Ecu doctors is one such company - I have never used them but I have read mostly good things about them. If they think the ECU is the problem there is a chance they can fix it. If the ECU is the problem and it cannot be fixed then you're looking at a hell of a headache. Matching ecu, immobilizer, and keys. If that's the case talk to Woody (itsnotanova) and he may be able to help you locate the parts.
