Aux fan used to run only on high when engine got hot, not over heated but more than warm. Fan never comes on with ac. I jumper the radiator fan switch(sensor) and the fan will run on high and low speeds while jumpered. I have checked/replaced every fuse and relay I can find and nothing is working. Originally the resistor pack was bad so I replaced that and made no difference. Going on a whim, I replaced the temp sensor, no help. ANYONE??🤔
