About the Universal Air Blower Resistor Product Line

The Blower Resistor line from Universal Air focuses on components that regulate the electrical current to the HVAC blower motor, controlling fan speeds within the vehicle’s heating and cooling system. The SW9966C is part of this product line, engineered to meet the specific electrical requirements of Jeep HVAC systems, ensuring proper airflow and temperature control inside the cabin.

Product Details and Functionality

The SW9966C blower motor resistor is an essential component in the HVAC system of Jeep Liberty and Wrangler vehicles. It modulates the voltage supplied to the blower motor, allowing for multiple fan speed settings. When this resistor fails, the blower motor may only operate at a single speed or not at all, affecting climate control performance. This replacement part restores the original functionality, providing reliable fan speed control and improving overall HVAC system operation.

Common Issues Resolved by This Blower Motor Resistor

  • Blower motor stuck on one speed or only high speed
  • Intermittent or no airflow from HVAC vents
  • Inconsistent fan speed control in Jeep Liberty or Wrangler
  • Overheating or electrical resistance issues in blower motor circuit
  • HVAC system failing to maintain desired cabin temperature

Installation Notes and Tips

  • Ensure vehicle ignition is off before installation
  • Locate the blower motor resistor near the blower motor housing
  • Disconnect electrical connectors carefully to avoid damage
  • Replace the resistor with part number SW9966C for compatibility
  • Verify proper blower motor operation after installation
