1998 Saturn SW2 service light reset

Hey, thanks for the timely response. I went and had the code(s) read, well, I tried to, but despite the idiot light that wont go off, the code reader said that there were no codes to read. PLUS, the stupid thing is still trying to overheat. I have had NOTHING BUT PROBLEMS with the cooling system on this car since I got the thing last June. From the word GO, the fan hasn't worked properly. It worked, at first, enough to where I didn't think there was a problem. After about a month, I realized that I had only actually heard the fan come on maybe 3 times. It starts overheating, and I end up replacing the fan and fan motor, the radiator, the thermostat, the coolant temp sensor, and the fan motor relay, thinking that my problems had to be solved after all of that. I was wrong. The fan still would not work, at all. I ended up throwing in a toggle switch for it, but neglected to install a fusable link, and ended up burning out the fan motor. It overheated, and popped a hole in the radiator. So, once again, I replace the radiator and the fan motor, and once again it does not work on it's own. I throw my hands in the air, install another toggle, (fusable link included), and my water pump goes out. Good times. I replace the water pump, and it still wants to overheat, fan on or not. It has started to death rattle when I accelerate, more than it used to, anyway. Is is already gone? Sorry for writing a book, but that's the 411 on my stupid freaking car. Any ideas?
