Pull the fan relay wirh the key turned on. With a test light check for power. one of them should be hot all the times. If not check your wiring. If you have power run a jumper wire to the prong across from it(assuming it is the big square relay) which should turn on the fan-if not you have a wiring issue after the relay. if it comes on run the car till its warm enough that the fans should kick on. check the other two prongs one should be a ground and the other should be power suplied by the temp sensor/switch. if your not getting power its between the sensor, pcm, and wiring.
