A BMW is a luxury car, and as such, you can expect a high level of quality components and high performance out of your vehicle.
Despite this fact, over time as a BMW accumulates mileage, it is going to need some BMW repair services. If you want to keep your ride flawless and smooth, keep up with routine care and maintenance repairs.
One popular BMW component that often needs repairing is the blower final stage fan resistor, which is part of your HVAC system. Here is a brief overview of what this piece is, and some signs that it may be malfunctioning.
Meet the BMW Blower Final Stage Fan Resistor
Outside of being a mouthful to say, the blower final stage fan resistor is an electrical component under the hood. It provides voltage to BMW’s HVAC fan.
“Blower final stage fan resistor is an electrical component that gives voltage to the HVAC fan.”
Often referred to simply as the blower motor resistor, it is essential to look at BMW repair options if you feel yours is failing. Without the blower motor resistor, your BMW HVAC system will fail, which means no air conditioning or heat. This can turn an enjoyable luxury ride into an uncomfortable and possibly dangerous ride based on outside air temperatures.
Issues that May Occur with Fan Resistors
Only BMWs with four or five fixed speeds have the blower final stage fan resistor. And in many newer systems, it’s inside of the HVAC system so that it naturally cools itself as air passes through it. This upgrade is a significant improvement. It helps prevent the blower motor resistor from needing BMW service as a result of overheating.
Every time you turn the fan knob inside of your BMW, the blower final stage fan resistor changes the speeds under which it operates. Thus, as a picky driver who is continually turning the knob to adjust the temperature, the fan is likely worn down. Each turn forces the blower motor resistor to speed up or slow down instantly. Of course, even if you aren’t constantly changing the fan speeds, over time, natural wear will catch up and push you closer towards needing BMW service.
Common Symptoms Your Blower Final Stage Fan Resistor May be Failing
Stuck on One Speed
Most of the time, the blower final stage fan resistor does not break down completely. Although when this does happen, the drivers find themselves unable to turn on the AC or the heat.
Instead, drivers will notice that the blower motor resistor gets stuck on one speed which allows air to blow but not at the speed you choose. Regardless of how many times you turn the knob, the wind will blow at the same rate. The only way to remedy this situation is by calling up someone to replace the fan resistor.
“The best way to avoid wind getting blown at the same rate, replace the blower final stage fan resistor.”
Air Vents are Blocked:
Of course, the other significant sign of a blower failure is when no air comes out of the air vents in the exterior in the BMW. This is a visible sign that BMW repair is necessary.
For air to come out of the interior vents, the blower motor resistor has to send the electrical current through the HVAC system to power it. If the piece breaks down, it is unable to address the current, and therefore, producing no air.
Where to Look for BMW Repair
The blower final stage fan resistor provides comfort as you navigate down the road. So, if it fails, then it is time to seek out help from a trained BMW repair specialist.
