HVAC Blower Motor Resistor Connector (2HAR0004) by Holstein®. Terminal Type: 2 Terminals. Global coverage of European, Asian, and Domestic vehicles. OE Replacement Parts You Can Trust. The Blower Motor Resistor is an electrical component that is a part of the vehicle's interior heating and air conditioning system. It is responsible for controlling the blower motor's fan speed. When the fan speed is changed via the dash controls the blower motor resistor is what changes the speed of the blower motor. A failed blower motor resistor can cause issues with the operation of the entire heating and air conditioning system. Usually a bad or failing blower motor resistor will produce a few symptoms that can alert the driver of a potential issue.
