Hey all
I was under the impression that the aux fans should engage when the AC comes on, is this correct?

My aux fans do not come on at present when I turn on the AC. I have to pull the connector to the water temp sensor (two wire) to get them to come on. When I return the connector to the sensor they stay on, even if I turn the AC off. This doesn't sound correct to me.

Any advice or testing procedure I can do? I really need these fans to operate properly now that I have functional AC.

Thanks
Steve A
