Blower Motor Resistor, 4-Spade Terminal Replacement SKU: QT52110

This blower motor resistor controls multiple fan speeds in your cab’s HVAC system. When the resistor fails, fan speeds may stop working or the blower may only run on high, making replacement essential.

Built with durable components and a sealed housing, it’s designed to handle heat, dust, and vibration inside cab environments. The 4-spade terminal layout provides a secure connection to standard blower motor wiring.

• Blower motor resistor with 4-spade terminal design
• Regulates multiple fan speeds for cab HVAC systems
• Durable housing to resist heat, dust, and vibration
• Direct-fit replacement for standard blower motor wiring assemblies

Installation Tip: Disconnect the battery before replacing. Remove the old unit, match the terminal positions carefully, and ensure the new resistor is seated and mounted securely to prevent moisture entry.

A reliable replacement part to restore full fan speed control and keep cab airflow consistent during daily use.
