Cooling fan switch its located at water pump, that is the coolant temperature sensor, car's PCM gets temperature signal from that sensor in order to turn fans on and off. Fuse block is in the engine compartment, driver side, there you'll see relays for primary and secondary fans. I hope that helps.

Like I said on the other thread, run current directly to the fans just to verify their condition. If they work directly... check connections, wiring and relays. If they don't run connected directly.... you guessed right, bad fan motor, probably burnt.

Have you seen the fans come on/off? Passenger side should turn on as soon as you turn your A/C on......
