Standard Ignition HVAC Blower Motor Resistor P/N:RU-446
Designed to restore variable fan-speed control to your heater and A/C, the Standard Ignition RU-44 is a direct-fit 1995-2005 Pontiac Sunfire blower motor resistor that also fits the 1995-2005 Chevrolet Cavalier. See the Buyer's Guide tab for engine details on your vehicle.
This HVAC blower motor resistor controls the current sent to the blower motor, so the fan can run at the different speeds you select. Standard Ignition designs it specifically for GM applications, and its research and design process aims for smooth integration with the vehicle's HVAC system.
Signs this part may need replacing include a blower that works only on high, skips one or more speeds, or will not run at all. Because a switch, wiring or the motor itself can cause similar symptoms, diagnose the cause before replacing the resistor.

Will this blower motor resistor fit my 1995-2005 Chevrolet Cavalier?
It is a direct-fit replacement for the 1995-2005 Chevrolet Cavalier and the 1995-2005 Pontiac Sunfire. The Buyer's Guide tab has the full fitment details.
What does a blower motor resistor do?
It controls the current reaching the blower motor so the heater and A/C fan can run at different speeds. If it fails, the fan may stop responding to some speed settings.
What are signs the blower motor resistor may need replacing?
Common signs include a fan that runs only on high, skips speeds, or does not run at all. A switch, wiring or the motor can cause similar symptoms, so diagnose the cause first.
Does the RU-44 have any built-in protection?
Yes. A built-in fuse protects against resistor failure from an excessive current surge, helping guard the blower motor and other components from damage.
What kind of connectors and terminals does it use?
It uses copper electrical connectors for precise resistance values and tin-plated steel terminals built to resist corrosion and provide strong conductivity.
