Why does your heater fan in your dodge 1500 van only work on high?

Your heater fan only working on high is probably the little coil sensor heater assembly located under the hood, it will be on the far left side of vehicle if your standing in front of it on the side of the air plenum. There is two screws holding it into the plastic chamber and a wire harness which you must unplug. Its right next to the transmission dipstick handle which is probably yellow like mine. I replaced mine for around 30.00 from the Dodge dealer and that fixed it. Good luck, hope this helps you!
