It is a known issue. You likely need a new switch, they burn the contacts with prolonged use.

I have a 2001 polaris sportsman 500 H.O. I have replaced the fan and the thermial fan switch,and checked the thermostat. Everything is either new or works there are no bubles in the coolant when its running I am running out of opptions . If I unplug the thermal fan switch and plug a jumper wire in the fan will run. I thought the new switch was bad and I tested it and it is good
