A blower motor resistor regulates the fan speed in a vehicle's HVAC system. By adjusting the electrical resistance, it controls the current flowing to the blower motor, allowing for different fan speeds. Typically, it uses resistive elements to provide low, medium, and high-speed settings. #BlowerMotorResistor #HVAC #VehicleMaintenance #FanSpeedControl #Automotive #ElectricalResistance #BlowerMotor #CarRepair #VehicleHVAC #AirConditioning #CareSkillsAcademy #ACrepairingcourse | Care Skills Acade
