Last night when I came back from dinner I noticed an extremely loud fan noise that I have never experienced before. The car wasn't overheating and I still have fair amount of coolant in the tank. When I opened the hood, it felt really hot and steamy and the fan was just blowing. Any ideas? Thanks in advance.

does the a/c work when those fans are running. there is a two pole blue coolant sensor. find 340-400 ohms resistance and bridge the connector with it and see if that works. if sensor is bad or out of range it could cause your problem. do not bridge straight
, ground or apply voltage to these wires. i replace about 1 a month for folks.

Thanks!! You're right...one of the sensors and its wires are bad. Dont know if I got ripped off but had it replaced for $175.
