Standard Motor Products RU994 Hvac Blower Motor Resistor

The Standard Motor Products RU994 is a direct-fit OEM-replacement HVAC blower motor resistor engineered to restore proper fan speed control to your vehicle's heating and air conditioning system. A faulty blower motor resistor is one of the most common causes of loss of fan speed settings — symptoms include the blower only operating on high speed, certain speed settings not working, or the fan not running at all. Replacing it with the RU994 restores full multi-speed operation.

Key Features:

• Controls electrical current flow from the fan switch to the blower motor, enabling multiple fan speed settings
• Direct-fit OE replacement — no modification required for installation
• High-quality ceramic construction with copper electrical connectors for accurate, stable resistance values
• Designed to meet or exceed original equipment specifications for reliable, long-term performance
• Manufactured as a 100% new component — contains no remanufactured parts
• Produced in TS16949 and ISO9001 certified manufacturing facilities for consistent quality control
