HVAC Blower Motor Resistor for Ford and Mercury

Global Parts 1712021 is an HVAC blower motor resistor for select Ford and Mercury vehicles. It is used in systems that need resistor-based blower speed control, helping restore proper fan operation in the cabin HVAC system.

  • HVAC blower motor resistor for select Ford and Mercury applications
  • Supports blower speed control in resistor-type HVAC systems
  • Direct-fit replacement for common OE cross-reference numbers
  • Fits 2010-2011 Ford Transit Connect, N/A
  • Fits 2000-2007 Ford Focus, N/A
  • Fits 2002 Ford Thunderbird, N/A
  • Fits 1999-2002 Mercury Cougar, N/A
  • Fits 1997-2000 Ford Contour, N/A
  • Fits 1997-2000 Mercury Mystique, N/A

Application Details

This Global Parts 1712021 resistor is used in HVAC systems that rely on stepped blower motor control rather than direct electronic fan regulation. It cross-references UAC SW11250C for the same application. Common vehicle coverage includes Ford Focus, Ford Transit Connect, Ford Thunderbird, Mercury Cougar, Ford Contour, and Mercury Mystique.

Common Symptoms It May Address

  • Blower motor works on only one speed
  • Cabin fan speeds are intermittent
  • HVAC fan does not respond at certain settings
  • Loss of low or medium blower speeds
  • Erratic heater and A/C fan operation

Installation Notes

Verify the original connector style and HVAC configuration before installation. Inspect the blower motor and related wiring for heat damage or corrosion, since a failing motor or damaged connector can shorten resistor life. Confirm vehicle fitment by year, make, and model before ordering.

Quality Assurance

Global Parts supplies this HVAC component as a replacement part for the listed Ford and Mercury applications. Part number 1712021 is referenced against common OE and aftermarket numbers for application matching.

This part fits 40 vehicles
Always verify fitment with your vehicle's VIN if unsure. Submodel & trim restrictions may apply.
