Product Details

This HVAC blower motor resistor is used in systems that regulate blower motor speed through electrical resistance. In vehicles like the Acura Legend, the resistor helps the HVAC system deliver the selected fan speed by managing current flow to the blower circuit. Global Parts 1712172 is identified for 1990 Acura Legend applications and is a practical replacement when the original resistor has failed or the blower speeds no longer respond correctly. This part number, 1712172, is also associated with cross-reference numbers 79330-SD4-003 and SW-739.

Common Issues It May Solve

• Blower motor only works on one speed
• Lower fan speeds stop functioning
• Intermittent HVAC fan operation
• No cabin airflow from the blower motor circuit
• Resistor-related HVAC control faults in a 1990 Acura Legend

Installation Notes and Tips

Verify the original resistor connector style and HVAC configuration before installation. Inspect the blower motor and related wiring for heat damage or corrosion, since a failed motor or damaged connector can shorten the life of the replacement resistor. Confirm fitment against the vehicle’s HVAC system before ordering.
