Thank you, but now I'm thinking it's the ECM, going to the dealer tomorrow.

Yes, but when that senor is unplugged it throws an Fi code on the dash and the fan will work but as soon as I plug it back in the fan stops which causes it to over heat both sensor and breaker have been replaced but it still not working. Relay is also functional.

When the sensor is unplugged the fan will cycle and run, when I plug the sensor back in the fan stops and will not run or cycle.

2011 Brute Force 750 I. Having an overheating issue. When fan sensor is unplugged by thermostat fan will run and cycle. When its unplugged it will not run and cycle. Need help. Really dont want to take to dealership.
