rad fan not work

[silvia-junkie]

i have a s14 sr with a koyo rad and a stock electric fan with no shroud. my problem is that when the car gets hot the fan doesnt turn on. the fan works if i jump the relay so i thought the relay was bad, i replaced the relay and it still doesnt work. i then wired a perminent jump over the relay with a fuse and the radiator fan then worked for a day with constant on(key on fan on). now to day the fan is backto not working. i checked fuses still good but no fan. now the jump was over the radiator hi relay now i can still get the fan to turn on by jumping the rad lo relay. does any one have any ideas on whats going on and if i jumb the lo relay will that stop working to?

sorry for the novel but anny help or ideas would be great, thx

wire it wo a switch, or get a fan controler

i would say to do it the right and nice way get the kit to wire it up that it turns on at a certain temp

Make sure your temperature probe tip is touching the radiator correctly, other wise the probe will never get hot enough to trigger the fan.

Stock electric fan doesn't have a temp. probe
