1998 Saturn SC2

Engine Cooling problem
1998 Saturn SC2 4 cyl Two Wheel Drive Manual 143000 miles

I have a used saturn, and my fan motor is shot because I put a direct line from battery to motor and nothing happened. But thats not the question, I purchsed a Saturn repair manual and I did my checks of the sensors and I'm stumped, Because to put it in lame mens terms, " The engine can't tell the radiatorfan to come on?

Does ur a/c clutch kick in when u turn on ur a/c?If so when u turn on the a/c ur radiator fan comes on with the a/c and stays on as long as the a/c is on. How did u test ur coolant temp sensor?Let me know.
