A-Premium HVAC Heater Blower Motor Resistor Compatible with BMW Vehicles - 745i, 745Li 2002-2005, 750i, 750Li 2006-2008, 760i 2004-2006, 760Li 2003-2008, Alpina B7 2007-2008, M3 1991 4.9 out of 5 stars 16 Reasons a Ford Mustang Heater Isn't Working. Ford Mustang. The most common reasons a Ford Mustang heater isn't working are a broken heater blower motor, a problem with the thermostat, or a failed heater blower motor resistor. 0 %. 31 % of the time it's the. When replacing your FSU, also consider changing the microfilter and inspecting the blower motor operation (a failing blower motor may be a contributor to premature FSU failure). This is a blower motor resistor made by ACM, an OEM supplier to BMW for many electrical parts. BMW Fitments: 3 Series E46 (99-05) > 320i E46 (99-05) > 323Ci E46 (99-05 The blower motor resistor is a single part, often with several possible pathways for current flow that provide more or less resistance, depending on the demand from the dash setting. When it fails — usually due to corrosion or overheating — you may notice a few things: Air flows, but only at high speeds, and other settings no longer work. MSRP Price: 234.96. BW Part #: 64116923204. Brand: Genuine BMW. (In Stock) Description. Customer Reviews. Blower fan problems in your BMW E46, E39, X3, and X5 are likely caused by a faulty blower motor resistor, also known as a blower regulator, final stage resistor (FSR) or final stage unit (FSU). This part regulates the fan speed coming from The blower motor resistor (or final stage) varies voltage to the blower motor to achieve the desired speed. If your blower motor fails and replacing the final stage unit has not remedied the problem, the blower motor itself is likely at fault. Over time, a blower motor may become noisy as the motor electrical contacts wear. The blower motor in your truck has a resistor block with multiple resistor wires. Each wire changes the resistance in the ground side of the blower circuit to change the speed of the motor. When the blower is turned to the high setting, the block is bypassed, allowing the blower motor a direct path to ground.

It’s responsible for pushing air into the cabin through the vents. It’s controlled by the fan control switch and blower motor relay, which are responsible for managing the amount of voltage the blower motor receives, allowing it to function at different speeds. When replacing your FSU, also consider changing the microfilter and inspecting the blower motor operation (a failing blower motor may be a contributor to premature FSU failure). This is the Genuine BMW blower motor resistor, part number 64116927600 (64 11 6 927 600), which is the most current of several design improvements and part number changes. What is a blower motor resistor? Heating systems with just 3 or 4 speeds use a blower motor resistor along with the speed switch to regulate the motor speed. The resistors are arranged in series to reduce the voltage in steps, depending on where in the series you apply power. Blower resistors can burn out. When that happens, you lose that speed. BMW 328i Blower Final Stage Fan Resistor May Fail - 119 reports. The blower final stage fan resistor is known to fail. Symptoms are the heater fan speed varies GfvUv4F.
