hello

i have a 1998 foreman 450es and when i sart it up some times the oil light stays on . if i tap on the fan control unit it goes off . sometimes when i am riding the light comes on or just flickers . when it does this the fan doesn't work . if i tap on the unit the fan will turn on . the connectors are all clean and tight and there are no broken wires . has anyone else had this problem i think i need a new fan control unit . any ideas
