Designed to restore variable blower speeds to your heater and A/C, the Standard Blower Motor Resistor RU-647 is the component that helps set how fast the blower motor runs. It is listed for many Saturn models, among them the 2001-2005 Saturn L300, 2001-2003 Saturn L200 and 2001-2003 Saturn LW200. See the Buyer's Guide tab for the full list.
As an HVAC blower motor resistor, this part places resistance in the blower motor circuit so the fan can run at its lower speed settings. If a failed resistor is why your fan works only on high or skips some settings, this unit replaces it.
A fan stuck on one speed can also come from the switch or the wiring, so confirm the cause before replacing the resistor.

Does RU-647 work as a blower motor resistor for the 2001-2003 Saturn L200?
Yes. It is listed for the 2001-2003 Saturn L200, the 2001-2005 Saturn L300 and the 2001-2003 Saturn LW200. Check the Buyer's Guide tab for every listed model.
What does a blower motor resistor do?
It places resistance in the blower motor circuit so the heater and A/C fan can run at the lower speed settings instead of only one speed.
What are signs the blower motor resistor may need replacing?
Common signs are a blower that runs only on high or skips one or more speed settings. A bad switch or wiring can cause the same symptoms, so diagnose the cause before replacing the part.
Why does Standard use copper connectors on this resistor?
Standard uses premium copper electrical connectors for more precise resistance values. It says this improves resistor performance and gives the part a longer life.
Which part numbers does RU-647 replace?
It cross-references to RU1337, DR766, BR548 and 90583344.
