It only comes on when I switch on the A/C. I replaced the temperature sensor, relay and fuse but still has come on. I checked all necessary wiring and connections and all good. What is the problem here?

Hello,

Okay, what relays did you check? There are two relays per fan. In the diagrams down below I have included the wiring diagrams for your vehicle's cooling fans circuit. Please go over it for reference and get back to us. We can go from there, if needed.

Thanks,
Alex

The car also give a whistling sound when I turn the steering completely lock either left or right. The belt and tensor bearing have been replaced.

Hello again,

I can answer this question for you, but for archival purposes could you please re ask this as a new question. If we answered this question it would be in the cooling fan thread and anyone looking for this answer in the archives would never be able to find it, so we do one question one thread. Thank you for understanding.

Thanks,
Alex
