Try changing the cooling fan relays first, sometimes they get pitting in the points and then they stick closed.

Where do I locate the cooling fan relays? How many are there ? Where can I purchase these ?

They are in the power distribution box under the hood and are usually marked, my RX had two, most parts stores should have them or can get them overnight.
