HVAC Blower Motor Resistor for GM Trucks

Restore proper blower fan operation with Global Parts part number 1712157. This HVAC blower motor resistor is a direct-fit replacement for select Chevrolet and GMC trucks and SUVs with manual A/C or factory air conditioning, including many C/K series applications.

Compatible With 1988-1994 Chevrolet and GMC C/K platform vehicles, this resistor helps maintain correct blower speed control in the cabin HVAC system.

Key Features

  • HVAC blower motor resistor for select Chevrolet and GMC applications
  • Supports blower speed control in manual A/C and air-conditioned systems
  • OE-style replacement for common GM truck and SUV fitments
  • Global Parts part number 1712157 for easy identification
  • This part cross-references Dorman - OE Solutions 973-537 for the same application

Detailed Description

Global Parts 1712157 is an HVAC blower motor resistor used in select Chevrolet C1500, C2500, C3500, K1500, K2500, K3500, Blazer, and GMC C1500, C2500, C3500, K1500, K2500, K3500 applications. It is also listed for several Suburban models with front-unit, 3-speed motor configurations. In the HVAC system, the resistor regulates blower motor speed so the cabin fan can operate at the selected setting. On vehicles with manual A/C, this component is commonly used to maintain consistent fan control.

The manufacturer notes that modern vehicle climate systems may use electrical switching feedback through the engine management system, while earlier vehicles may use direct compressor control to help prevent compressor-related failure. For buyers searching by vehicle, this part number 1712157 is a practical replacement for Chevrolet and GMC HVAC blower motor resistor service on the listed model years.

Common Problems This Part May Address

  • Blower motor works on only one speed
  • Fan speeds stop responding at the HVAC control
  • Intermittent cabin airflow from the vents
  • No blower operation on manual A/C systems
  • Resistor failure in older GM truck and SUV HVAC systems

Installation Notes and Tips

Verify the vehicle’s HVAC configuration before ordering, especially manual A/C versus other system types and any notes for front-unit or 3-speed motor applications. Compare the original connector and mounting location to the removed part before installation. Confirm fitment for your exact Chevrolet or GMC model year, since the listed applications vary by platform and HVAC setup.

Quality Assurance

Global Parts 1712157 is cataloged as an OE-style replacement HVAC component for the listed Chevrolet and GMC applications. Fitment is defined by the vehicle data provided for this part number.

This part fits 246 vehicles
