Take command of your cabin fan speeds with the Standard Ignition HVAC Blower Motor Resistor RU-647. It drops in as a direct-fit replacement for the 2001-2002 Saturn L100, 2001-2003 Saturn L200, 2001-2005 Saturn L300, 2000 Saturn LS, 2000 Saturn LS1, 2000 Saturn LS2, 2000 Saturn LW1, 2000 Saturn LW2, 2001-2003 Saturn LW200, and 2001-2003 Saturn LW300.
A blower motor resistor sits in the HVAC circuit and adds resistance to the blower motor's feed, stepping the fan down to its lower speed settings while high speed runs straight through. When a resistor circuit fails, you often lose one or more of the lower fan speeds while high may still work.
- Fan-speed control: provides the resistance that sets the blower motor's lower speeds.
- Direct-fit replacement: fits the listed Saturn L-series applications.
- Signs it may need replacing: if the resistor is the cause, some fan speeds stop working while others still function.

Frequently Asked Questions
What does this blower motor resistor do?
It adds resistance in the HVAC circuit to set the blower motor's lower fan speeds. High speed typically feeds the motor directly, bypassing the resistor.
Which vehicles does the RU-647 fit?
It's a direct-fit replacement for the 2000-2005 Saturn L-series, including the L100, L200, L300, LS, LS1, LS2, LW1, LW2, LW200, and LW300. See the Buyer's Guide tab for the full list.
My fan only works on high — is this the problem?
A failed resistor commonly causes a loss of one or more lower fan speeds while high still works. Diagnose the cause first, since other components can produce the same symptom.
What numbers does this part interchange with?
It cross-references RU1337, DR766, BR548, and 90583344. Its own manufacturer part number is RU-647.
Is this a direct-fit replacement?
Yes. The RU-647 is a direct-fit replacement for the listed Saturn L-series applications.
