Hi, there no relay. If the blower motor is good, but won't turn on, there used to be a recall on that. You can call your dodge dealer, see if they will fix it for free? Voltage to blower motor goes hot when you turn on the key. On and off-- different speeds is controlled on the ground circuit.
With the recall, the problem was wiring harness under the dash, the connector was trying to melt, because voltage to blower motor hot all the time, key on. The connector wasn't heavy duty enough.
There is a blower motor resistor on top of hvac housing, under right side of dash.
