Thread resurrection...
I am having fan issues. The fan works when the low OR high-speed terminals on the radiator temp sensor are jumped, but neither work with the AC off below 220F (when I turn it off for being too hot).
I don't understand why jumping both low or high-speed circuits will turn the fan on, but plugging it into a NEW Facet brand radiator temp sensor doesn't trigger the fan.
New radiator temp sensor, radiator, thermostat, water pump all installed recently. Fan does not operate as it should. |
