Replace an overheated or corroded blower speed resistor with the Dorman HVAC blower motor resistor kit, part number 973-416, which pairs a blower motor speed resistor with a harness pigtail to control the fan speeds of your heating and A/C system. It fits many vehicles, among them the 1997-1998 Dodge B2500, 1997-1998 Dodge B3500 and 1997-1998 Dodge B1500. See the Buyer's Guide tab for the full list and engine details.
- Resistor and harness pigtail: each kit comes with both a resistor and a harness pigtail, which Dorman notes is essential for most repairs, so the wiring connector can be replaced along with the resistor.
- Direct replacement: designed to directly replace the original equipment resistor and harness on the listed applications.
- Built to perform like OE: made to perform like the original equipment, helping return normal HVAC blower operation when the resistor is the fault.
- Position: cataloged for front and rear positions on the listed applications.
- Engineering support: backed by Dorman's team of engineers and quality specialists in the USA.
A blower motor resistor lowers the voltage sent to the blower motor to create the reduced fan speeds. Signs it may need replacing include a blower that runs only on high, one or more fan speeds that no longer work, or a scorched or corroded connector. If a failed resistor is the cause, this Dorman blower motor resistor kit replaces it. Diagnose the blower circuit first, since the motor, switch or wiring can cause similar symptoms.
