Standard Motor Products RU308 HVAC Blower Motor Resistor

The Standard Motor Products RU308 is a direct-fit replacement HVAC blower motor resistor engineered to restore proper fan speed control to your vehicle's heating and air conditioning system. The blower motor resistor controls the electrical current flowing from the fan switch to the blower fan, allowing the driver to select from multiple fan speeds.

Key Features:

• Direct-fit, OE-style replacement for a hassle-free installation
• Manufactured using highest-quality components matched to original fit, form, and function
• Sample-tested for draw, resistance, and RPM to validate performance at all speeds
• Validated to precisely match OE specifications and meet or exceed OE durability standards
• Subjected to 48-hour load testing to ensure long service life under all operating conditions
• Manufactured in IATF 16949-certified North American facilities
• Sold individually

A faulty or worn blower motor resistor can result in the loss of one or more fan speeds—or complete loss of blower function—leaving you without heat or air circulation. Replacing the resistor with a quality Standard Motor Products unit restores full variable speed control to your HVAC blower motor. Note: When replacing the blower motor resistor, it is recommended to inspect the mating connector for heat damage and replace if necessary.
