BMW is a top-quality automotive brand that is known for producing high-end vehicles with exquisite features, outstanding engine performance, and top-of-the-line interior comfort. Although BMWs are built to withstand the test of time, they may experience issues including HVAC blower failure.
What is the HVAC blower?
BMW is designed and manufactured with the comfort of the driver in mind which is why the makers of these automobiles strive to produce high-quality components such as the HVAC system. HVAC is an acronym for Heating, Ventilation, and Air Conditioning and is what provides your BMW with air conditioning and heat for a comfortable ride.
The HVAC system is made of several parts, including the HVAC blower. It is responsible for forcing hot air through the vents when you turn on the heat and cold air when you are using the air conditioner. This is both controlled by turning the climate control unit on your BMW’s dashboard.
Warning Signs of HVAC Blower Failure
As with all parts that make up a BMW, the HVAC blower is at risk of failure. If this part is unable to maintain itself and function as intended, it will produce a few symptoms or warning signs that will alert the driver to a problem. These warning signs include:
● Poor airflow: When the HVAC blower is working appropriately, you are sure to feel comfortably cool in the middle of summer and cozy during the winter months. But when the HVAC blower fails, there is an insufficient amount of air flowing from the vents leaving you incredibly uncomfortable.
● No airflow: This is probably the most obvious warning sign of a failed HVAC blower. No air flowing from your vents regardless of how high or low you set the climate control unit indicates a problem that needs a professional to repair it.
● Insufficient temperatures: A failing or failed HVAC blower is unable to keep up with the desired temperature set through the climate control unit.
Common Causes of HVAC Blower Failure
As the owner of a BMW, you know the luxurious comforts that come along with it. In turn, you also notice almost immediately when these comfort features are not working appropriately. A properly functioning air conditioner and heating system is at the top of the list of comfort measures. Below are two of the most commonly reported causes of HVAC blower failure in BMW.
A malfunctioning relay
The heating, ventilation, air conditioning system, and blower are made of many small parts that work together. When one of these parts is unable to function properly, it can cause the whole blower and system to fail.
The blower system utilizes several electrical pieces and wiring to help the system communicate. When one of these relays fails to do its job, the blower motor can no longer force air through the vents.
Normal wear and tear
All vehicles, regardless of age, make, or model are subject to normal degradation from constant use and environmental factors. The HVAC blower found within the heating, ventilation, and air conditioning system of your BMW is not immune to the ravages of time. This is one of the systems that you will have to maintain and repair as it ages. This is a normal part of car ownership.
