Hope that helps.

 

Key on, remove the wires/connector from thermo a (green connector by t-stat), use a paper clip or something and jump the two wires together....do BOTH fans come on?

 

im having the same issues too with my cooling fan. at first it was the green wire to the temp gauge sensor that broke off and i just fixed that problem and the gauge is now working fine. and then i just replace the coolant temp switch next to that one. but the fan isnt turning on and the engine temp just sky rockets. is there something else i should check.

everything was working perfectly fine until the wire broke on the coolant temp gauge.

i would appreciate any help.

 

Not sure if you replaced the correct switch?

Anyway, have you ruled out a bad t-stat, your comment about the temp "sky rockets" makes me ask this.

Then, thermo a (green connector by the t-stat-lower hose) controls the fan operation when the car is on...not close to the single wire temp sending unit on the end of the head.

 

ok this is what I have done to the car new radiator new fan switch sensor new temp sensor new cooling fan sensor so all the sensor are new and so is the thermostat new relays so WTF is going on dang it

 

assuming you have installed all correct parts in the correct location the only thing you haven't changed out is the fan control unit
