The best comfort to have when inside the a BMW especially on long drives and travels would be the existence of an air conditioning system that will give us that comforting cool wind during summer, and the heater making the car cozy during winter. One of the most significant parts of the AC and the heater would be its BMW blower motor resistor. If you’re not familiar with this one, your BMW 323i blower motor resistor is mounted to the bottom of the heater or your air condition’s housing on the passenger side of the automotive under the instrumental panel. To access it, all you have to do is remove the instrument panel glove box. Your 2000 BMW blower motor resistor is made of multiple resistor wires. Each of these wires reduces the current flow to the blower motor, changing the motor speed. This is then directed to the battery current by the blower motor switch and is brought to the correct resistor wire to obtain that selected speed. When the highest blower motor speed is achieved or selected, the blower motor relay connects the blower motor directly to the battery current, bypassing the blower motor resistor. When your BMW 323i blower motor resistor is damaged or is faulty, this cannot be repaired and the only option would be to replace it.
