There could be a small 20 amp breaker that protects the fan circuit. If it gets corroded or goes bad, no power to the fan. Look in the fuse box area. Not sure where or if there is one on these. The Rzrs were having probs. If you find it, examine connections. This is always hot, so disconnect the battery if you work on it or you could fry the computer.

My 2011 400 had fuse panel under panel under the light pod. The circut breaker could even be back by the battery wrapped up in a harness. It is about 1" by 2" part.

So I changed the temp sensor and the circut breaker, still no fan. Both upper and lower rad hoses are warm and engine does not seem to overheat so I assume thermo and water pump are working correctly. Temp sensor at block? My only problem seems to be a hot steaming rad, otherwise bike is running as it should. Any ideas, Is it safe to run the fan direct to a 12V sorce that is on when the bikes on?

I have heard some have a bypass switch to turn off the fan in deep water, so I would think you could fix it to manually turn on as well.
