the ONLY time your fan should kick on is when your car is sitting in the same spot for more then 5-10 minutes, it shouldnt kick on during regular driving, its probably your thermostat ($6)

Re: overheating problems
your fan motor probably pooped itself out, go to a junk yard and get another, at worst youll have a backup fan when it actually does pooop

after looking through my haynes manual i found this, theres a such thing as a "coolant temperature sensor" i would assume your computer uses this to determine when to turn the radiator fan on and off, if its bad the computer wont get the singal, hence, it wont turn on the fan (i think) anyways, to remove the sensor, it says to release the locking tab, unplug the electrical connector, then carefully unscrew the sensor, you said its a 99, if its a 2.2 the sensor is installed in the coolant bypass pipe at the right front corner of the clyinder head, near the alternator, if its a 2.4 its located on the thermostat housing cover, hopefully this helps

Re: overheating problems
I bet you have a bad head gasket now, do a oil change look for contamination

Re: overheating problems
basically take the fan off, and hook it directly to a battery with 2 wires, if it runs, its good. If not, its toast get a new one or used. If it runs, its your sensor. Replace
