I put an override switch on my aux fan so I can control when I want it to come on. Works great..... except for one goofy thing. I can get it to work great until the engine hits 220* then the fan shuts OFF. Power is still being supplied and has not been interrupted but fan won't run again until it cools off.
So I completely bypassed the wiring from the ECU and wired the fan direct to an independent relay and still get the same results :huh:. I thought maybe it was getting a thermal signal from the ECU to shut off. So being independent from any other signal, I'm assuming there's some type of thermal relay inside the fan??? Or does the plug that connects the fan to the ECU have a built-in thermal "switch"??
