SubaruWagon87 Posted November 16, 2008 Share Posted November 16, 2008 Or coolant temp sensor? I'm not sure exactly what they're called. Anyway, is there anyway to test it? I replaced the old one with a new one, and it didnt do the trick. If I were to say, take the switch out, hook up some wires, a light, and a battery to it, and place it in heated up water, would the light turn on?

4WDFrenzy Posted November 16, 2008 Share Posted November 16, 2008 Is the electric fan not turning on, or is the temp gauge not reading correctly? Patrick Link to comment Share on other sites More sharing options...
SubaruWagon87 Posted November 16, 2008 Author Share Posted November 16, 2008 The temp gauge works fine, and the fan's not turning on. Link to comment Share on other sites More sharing options...
Turbone Posted November 16, 2008 Share Posted November 16, 2008 Have you direct wired the fan to see if it works? Link to comment Share on other sites More sharing options...
SubaruWagon87 Posted November 16, 2008 Author Share Posted November 16, 2008 Yes, thats how I had it after I discovered the switch wasnt turning the fan on. Link to comment Share on other sites More sharing options...
NorthWet Posted November 16, 2008 Share Posted November 16, 2008 Did you try jumpering the thermo-switch at the connector (take a wire or straightened paperclip and stick one bare end into each side of the connector)? This should test all portions of the circuit except the t-switch. Link to comment Share on other sites More sharing options...
SubaruWagon87 Posted November 16, 2008 Author Share Posted November 16, 2008 I might give that a try tomorrow. I might end up bypassing the stock fan circuit though because I think I'm going to run dual fans. But until then, I'll see what I can do to get the single fan working.

Cougar Posted November 16, 2008 Share Posted November 16, 2008 Make sure that you have voltage getting to the switch. Check the fuses. Link to comment Share on other sites More sharing options...
4WDFrenzy Posted November 16, 2008 Share Posted November 16, 2008 diablo_stallion3, if you are going to run dual fans, and do any rewiring, check with Autozone as they sell adjustable fan control switches. Then you have the option of making the fans kick on at a temperature of your choosing. Best of Luck to you. Patrick Link to comment Share on other sites More sharing options...
SubaruWagon87 Posted November 16, 2008 Author Share Posted November 16, 2008 Make sure that you have voltage getting to the switch. Check the fuses. I remember there is voltage getting to it because when I replaced it I tested all the wires with a test light, so theres a possibility that the new switch could be bad. :-\ diablo_stallion3, if you are going to run dual fans, and do any rewiring, check with Autozone as they sell adjustable fan control switches.

I did a search at autozone.com and didn't see any adjustable ones. Link to comment Share on other sites More sharing options...
Cougar Posted November 16, 2008 Share Posted November 16, 2008 The thermoswitch turns on the fan by completing the ground circuit to the fan. You should be able to active the fan by following the advice that NorthWet gave. Remove the connector to the switch and jumper those connections together in the socket. If that doesn't work then there is a high resistance connection between the power source to the fan and that connector or one end the connector isn't connecting to ground.
