Most likely the motor itself, turn on the AC (if it works), the fan would be on if it worked. USING a screwdriver push the fan blade and/or tap on the fanmotor housing to see if the fan will start turning.
If so relace the fan, if not repost for electrical help with the circuit.

The easiest thing to do is to disconnect the coolant fan relay and test the wiring to it. With the ignition on, there should be two power supplies to the relay. The other two connectors will be dead. Locate the thick wires that go to the relay connector. One will be the power supply and the other is the wire that goes down to the motor. I used to jump this connection so as to attempt to send power down to the coolant fan motor. If you do this the motor should run. If it does not run, unplug the motor connection and test for power and ground with the relay still jumped to power. If you have both power and ground, the motor is humped. If you have no power to one or both of the relay connections, you either have a blown fuse, a blown fusible link, a broken wire to the relay, or a combination of some of these. The most common problem is the motor burning up, which would cook the relay due to high current, and that would finally blow the fusible link. If this is the case, replace the fusible link and the relay. Then check to be sure that the power and ground are deliverable to the motor. If that is good, replace the motor as well as it is probably drawing too much current or already shorted.

there is a simple test you can do...but depending on the outcome it can get more involved.
Step 1: check the fuse...if it is blown dont replace it yet... it is open for a reason.
Step 2: remove the fuse BLOWN OR NOT. remove the ignition key. Using care try to spin the fan(s) with a screwdriver...keep in mind there is a small chance they could come on...but not likely. if the fan does not spin eaisly...thats the issue,and why the fuse may be blown. if it spins ok.....step 3
Step 3: Check power and ground. heres where it gets tricky. You should use a wiring diagram and a test light...or better yet a digital multimeter. a manual is available for this car at most auto parts stores. so....no power =wiring issue, relay or ecm. no ground= wiring, corrosion or loose ground. hope this helps!

It's either your coolant sensor or your fan itself,hook the fan up direct to a battery and if it doesn't come on then it's the fan,if it does come on then it's the sensor. Trust me I am a mchanic You could even hook the fan up direct to a toggle switch, just make sure you turn it on when you are stopped and idling.
