Surviving winter with BMW Heating System Malfunctions: Causes & Cures from Experts in West Palm Beac

The unforgiving winter punishes everyone and nothing is more comforting than driving the BMW with its heater on. But you might get a rude surprise when you find that the heating system of your car fails to provide you with hot air when you turn on the heater.

There are multiple factors that can cause the heating system to malfunction. Here are the causes of heating system failure in your BMW as shared with us by the expert mechanics in West Palm Beach, FL.

Thermostat Failure

A leading cause behind the malfunctioning of the heating system in your high-end BMW is related to thermostat failure. The thermostat is a crucial part of your vehicle that helps in the proper circulation of coolant throughout the car by holding back the coolant when the engine starts.

This allows the engine and its components to heat up faster and on reaching a particular temperature when the coolant is released it circulates throughout the engine and gets heated up. The heated coolant is what provides you with warm air when you drive.

However, when the thermostat malfunctions in your car it prevents the coolant from circulating in the engine properly. This causes problems in the functioning of the heating system of your car because the coolant is released instantly without being held back by the thermostat & it fails to heat up rapidly.

Due to this the heating system of your car will take time to provide you with hot air. You must get in touch with a BMW specialist who will diagnose the thermostat & fix it accordingly.

Faulty Fan Motor

Another prominent part of your HVAC system that plays a stellar role in the functioning of the heater in your vehicle is the fan motor. The fan motor helps in the flow of air over the heater core and then the air blows through the vents of the vehicle.

The fan motor is an electrical part of your vehicle and like other electrical components, it is also prone to electrical problems like malfunctioning fuse which will adversely affect the functioning of the fan motor. Most people are not able to comprehend the problem with the fan motor & blame other parts for the failure of the heating system in their car.

In addition to this, as your BMW picks up miles the fan motor might encounter issues with its functioning because of continuous usage & replacing it will be the only option for you to get back your heating system on track.

Inadequate Coolant

The coolant is a vital fluid in your BMW that not only helps in preventing the engine from overheating but also helps in the efficient functioning of your heating system. Most drivers are surprised to know that the heated coolant is the primary source of the warm air they receive from the vents of their car.

The heat collected by the coolant when circulating through the engine gets dissipated in the form of warm air when you turn on the heater. However, it is often observed that the presence of low levels of coolant adversely affects the functioning of the heater core in vehicles.

Moreover, inadequate levels of coolant can also lead to other issues like overheating engine and you need to immediately take steps in filling up the coolant in your car.

Bad Heater Core

A failing heater core in your vehicle can also play spoilsport in the functioning of the heating system and make your winter drives dreadful. Most of the time leaks are detected to be the primary cause behind the failure of the heater core in BMW.

If your heater core has developed a leak, then it won’t be able to provide you with sufficient warm air & will also cause the coolant to leak into the cabin of your car. This will become evident when you experience a sweet smell inside the cabin of your car all of a sudden.

Replacing the heater core of your high-end car is quite complex & you need to visit a qualified mechanic or BMW-authorized service center to get your heater core replaced at the earliest.

Finally

The above-discussed factors are the prominent reasons behind the malfunctioning of the heating system in your vehicle. Now, whenever you happen to come across your heater not functioning properly, then take your BMW to a certified repair shop to get it inspected & fixed before the cold weather catches up on you.
