Our 2003 (?) ranger is overheating.  The fan isn't coming on.  We've taken it to a shop several times and they charge us $100 or more and it still isn't right. We hooked up a hot wire directly to the fan and it worked.  Any suggestions??  

I just went through the same thing with my 05 800 Twin. Had the whole front of the bike apart. Replaced Fan with aftermarket, checked all the wiring, etc. I was down to what I think is an inline fuze/circuit breaker in a supposedly sealed pouch. When I was moving it around all of a sudden the fan started working so I figured it was shorted or wire loose. cut the pouch apart and the relay/switch was all corroded, to the point the wires were barely connected. The tugging and pulling would cause the fan to come on or off as I played with it. I AM ON THE WAY TO THE AUTO PARTS STORE TO FIND SOMETHING SIMILIAR AND MINE SHOULD BE FIXED.  

Have Ranger 6x6 700efi, is heating up. have changed water pump ( didn't need it ) and Antifreeze. waiting on thermostat. Running without it right now appears to be almost normal......pump immpellor was 22 bucks, seal for behind impellor 68 bucks, thermostat is coming in at 55 bucks. hope this works............
