My dad has an 07 3010 mule and the fan quit working. Plunged it in and it came on if we manual power it so the fan is good.
Fuse is good, has full coolant, and no wires seem damaged. What could be the problem?

I know my rzr had some sort of relay under the seat that corroded and made it stop working but don't see one on the mule.

Yes the temp light comes on because its getting to hot.
