Standard Ignition HVAC Blower Motor Resistor P/N:RU-67

Take command of your climate control's fan speeds with the Standard Ignition HVAC Blower Motor Resistor (P/N: RU-67, also written RU67). This front HVAC resistor drops in as a direct-fit replacement for many Chevrolet and GMC trucks, vans and SUVs, among them the 1973-1986 Chevrolet C10 Suburban, the 1975-1986 Chevrolet C10 and the 1979-1986 GMC C1500. See the Buyer's Guide tab for the full list of applications.

The blower motor resistor sits in the front HVAC circuit and adds resistance to the blower motor feed, stepping the voltage down so the fan runs at the lower and mid speeds you select on the control panel.

• Fan-speed control: Provides the resistance stages that give you the low and medium blower settings.
• Front HVAC application: Serves the front heating and air-conditioning blower circuit.
• Direct-fit replacement: A direct-fit replacement for the listed applications.

If a failed resistor is the cause of blower speeds that cut out or a fan that only runs on high, this replaces it. Diagnose the circuit before ordering to confirm the resistor is at fault.
