Thermo switch pigtail/wire location ?

[90blacktsi]

Does anybody have a picture of where the connector from the thermo switch in the bottom of the radiator comes from . My fan does not turn on and I cant seem to find where in the harness it would come from . I also noticed that there are 2 fan relays and two ac relays on the GVR4 , Do I have to jump both fan relays to test the fan? Fan does not turn on with the ac button either , But does turn on when jumped to the battery . Car was running on AEM EMS , not sure if they had it wired differently , but it turn on .. Car is know on ECM LINK . Thanks , Any info will be helpful

Bypass the resistor and see what happens. Both of my GVR4's had bad ones.

How do you bypass the thermo resistor, by cutting the wires that feed too both ends and connecting them? I was looking at wiring schematics yesterday, my eyes still hurt plus I'm feeling a little lazy.

That's what I did. Works great. But I would test it first by using a jumper to bypass the resistor. Just connect a wire from one side to the other to see if that's the problem or not.

By the resistor do you mean the sensor on the bottom of the radiator ? If so I cannot do as you stated . All I have is the sensor on the rad . No wires to jump . Cant find them anywhere .

It's the big white ceramic resistor enclosed in a metal cage mounted near the top of the passenger side radiator fan.

The harness comes down the passenger side of the radiator. The plug is white (when new /ubbthreads/images/graemlins/wink.gif in color.

All good info thanks ! Still need some more though . Here is a pic of my setup . You can see the plug for the fan has 6 wires I think and only two that comes out that go to the fan ( slim fan ) The only thing I can think of is that on a stock plug splits off into two different harnesses and thats why all the extra wires are not in use . What I need to know is the color of the wires that go to the thermo switch . Thanks
