GPD 1712708 HVAC Blower Motor Resistor Control Module

The GPD 1712708 is a direct-fit HVAC Blower Motor Resistor (also commonly referred to as a Blower Motor Control Module) designed to restore proper fan speed operation to your vehicle's heating and air conditioning system. This replacement resistor regulates the electrical current delivered to the blower motor, enabling precise control over cabin airflow at multiple fan speed settings.

On vehicles equipped with automatic climate control, the blower motor resistor acts as an electronic controller — adjusting blower motor speed to match your selected comfort level. A failed resistor commonly results in the fan operating only at full speed, no airflow at all, or erratic speed behavior. Replacing this part is a straightforward, DIY-friendly repair typically completed in under 30 minutes. The resistor is located in the passenger-side footwell, mounted directly to the HVAC housing near the blower motor.

Key Features:

• Direct-fit replacement for original equipment blower motor resistor / control module
• Restores full multi-speed blower fan control to the HVAC system
• Manufactured to meet or exceed OEM specifications for fit, form, and function
• Compatible with vehicles featuring automatic climate control systems
• Built by GPD (Global Parts Distributors), a trusted aftermarket HVAC specialist since 1974
• Backed by GPD's one-year manufacturer warranty against defects in materials and workmanship

Installation Note: Always ensure electrical components are free of debris and moisture before installation. If the existing resistor shows signs of melting or burn damage, inspect the blower motor as well — a failing blower motor drawing excess current is a common cause of resistor failure and both parts may need replacement.
