Those of you people that own a dodge sometimes run into you heat or air conditioning blower only working on high. Common Fix for that would be the blower motor resistor, but hold on dont go running to the dealer to buy the part. Check for the location of it on your vehicle then pull the connector and check the terminals to make sure they are not burnt. If so you will need a connector package to go with that blower motor resistor. Also suggest replacing the blower motor itself.
