Agreed - Also, when the resistor fails, it almost always takes out the wiring plug with it b/c the fans come on so seldom that you typically don't notice the low speed fans failed until several months later.

I wonder if mounting the resistor in the fan shroud (High heat) contributes to the problem or not.

Insufficient feed wiring IMO, and yes, there is an ambient temp factor that affects conductor size. There just aren't enough engineers that realize this.

This one is for the OP, are you interested in parting ways with that resistor you ended up not needing? I need one, and I'd rather help someone on the forum than go searching for a buy it now listing.

hi and welcome to the forum. In the future, better to start a new thread than to glom on to an old one.

Before drawing any more conclusions about the temperature sensor, it might be worth your time & $ to reinstall the sensor and then start the engine with the odometer in test mode. To learn about that, click the "Stickied Threads" link at the top of this forum, and then click the "Complete HOW TO" link. Then, scroll down and click "Focus Test Mode". That will cause your odometer to read in degrees Celsius.

With the A/C off, the two fans should being operating in their low-speed mode around 110C and in their high-speed mode around 116C (although if your engine is just idling and the cooling system is working properly, then it should never reach 116C).
