How to Maintain a Blower Motor Resistor on Dodge Ram 2500?

On automobiles with air bags, you should begin by isolating the battery negative cable, letting the air bag capacitor discharge for two minutes and then going ahead with the blower motor resistor service. A good first step is to disconnect the wire harness connector from the blower motor resistor, found under the passenger side end of the HVAC housing. Following this, unscrew the blower motor resistor from the HVAC case and remove the resistor. The resistor should be placed in the HVAC housing and attached with screws that are tightened to 2.2 Nm or 20 in. lbs. After that, attach the wire harness connector to the blower motor resistor and put back the negative battery cable.

To start, remove the negative battery cable from its socket to disable the air bag system; afterwards, you should wait two minutes for the capacitor to disconnect. It's important to give the blower motor resistors a five-minute cooling period if the motor was running before, because they often get very hot from use. It is most important to first remove the negative cable from the battery. After that, go under the instrument panel next to the blower motor and unplug the wire harness from the blower motor resistor.
