As an owner of the BMW brand, you expect your car to have all of today’s contemporary automotive amenities, including a fully functional HVAC system. The very last thing on your mind should be shivering in winter or getting cooked in your BMW during summer due to a broken HVAC blower. BMW maintains high standards for its automobiles, but they’re not immune to production errors, and some parts are just susceptible to failure over time as a result of general wear and tear.
Heating, ventilation, and air conditioning are abbreviated as HVAC. Its purpose is to force heat or air conditioning into the cabin via the vents. It also sends heat into the cabin to clear the glass, which would otherwise fog up in cold weather because of the hot air in your breath, reducing the driver’s view. This might endanger you as well as other drivers.
Blower HVAC Failure Symptoms
When HVAC, just like all other elements of a car, begins to fail, one will notice some signs. These are a few of the noticeable signs that will appear if your car’s HVAC blower fails:
- Strange noises whenever the fan is turned on: If you hear cracking or slapping sounds from the right-hand side of the vent, it is most likely a piece that was pulled into the vent and now slamming against it.
- Minimal or no flow of air: Weak or no airflow from your vents is among the first symptoms that indicate that your HVAC system is malfunctioning. You may have to set the blower up to a higher level to achieve the regular airflow you are used to. You might also note that your car’s defrosters may be malfunctioning.
- Ventilation Smoke: You should not be concerned about white, unscented condensation emanating from the air vents. It is caused by cold, dry air having contact with milder, moister air around the conditioner. However, if smoke with an odor comes out of the vents, you must immediately switch off the blowers, lower your windows, and stop the car. You should exit your car immediately as the fumes or smoke might hurt you. Have your vehicle hauled to our qualified technicians and do not drive it any further.
- Only has a single speed: Whenever this occurs, it is possible that the switch of the fan is faulty. However, it is most likely the resistor of the blower motor. Whenever this resistor malfunctions, the maximum fan speed normally stays operational. This is due to the fact that it basically skips the resistor and obtains maximal voltage.
Blower Failure Causes
We have two major reasons for HVAC blower malfunction in BMWs, which we will discuss below:
- Natural wear and tear. Some HVAC blower problems emerge as a result of natural vehicle depreciation as the vehicle travels long distances. Parts deteriorate and break as a result of repeated usage and exposure to the elements. HVAC blowers are designed to survive the whole life of the vehicle, however, they are prone to breaking based on the extent of some climatic conditions.
- Relay Components That Aren’t Working; Your car’s HVAC blower is composed of various technical pieces that might break down, causing the entire system to fail. It has the potential to cause the entire blower system to fail. In most situations, the problem is caused by a burned-out blower motor or a fault in the electrical wiring.
