The colder periods are approaching, and the last thing you need right now is a problem with your BMW’s heater. Having to struggle with a faulty heater can prove to be a very big discomfort. Nobody wants to struggle with a malfunctioning heater in increasingly cold climates.

Often BMW vehicles have been reported to have heater issues, so this problem is not particular to your vehicle alone. If you’re on this page right now, then you’re doing the right things to aim at repairing your BMW’s heater issue. We will run through the reasons why your heater may malfunction and how to get it fixed.

Your BMW’s Cabin Heating System

First, you need to know that there is an entire system in your BMW that regulates the car temperature. It utilizes heat from the car’s engine and coolant from the reservoir to warm up a heater core. The heater core dispenses warmth into the cabin of your vehicle to ensure you stay warm on a chilly day.

Causes of a Malfunctioning Heater

Next, to fix the problem with your BMW’s heater, you have to first know why it is faulty. There are various reasons why your BMW’s heater is malfunctioning and some of them shall be explained here:

  • A Broken Thermostat: A faulty thermostat, if not quickly fixed, could result in extensive damage. Leaving your thermostat faulty or broken would obviously stop your heater from working but it can also go on to damage your vehicle’s engine.
  • A Clogged Heater Core: When you use the vehicle over time, it is possible for debris, dirt, and grease to clog up your heater core. Aside from the debris that could get in from the outside, there is a possibility of radiator rust getting into the cooling system, which can later get stuck in the heater core.
  • Overheating: A leak in the coolant system of your vehicle is dangerous. When the coolant system leaks, it causes the radiator and the heater core to get hot. This could consequently cause the vehicle to overheat. If this is not fixed as soon as possible, it could lead to further engine damage.
  • Broken Heater Fan: Even if the heater core is working optimally, a faulty or broken heater fan could prevent the hot air from entering the cabin of the vehicle. The heater fan is the component that blows the hot air into the car, and if it is faulty due to electrical shorts or other reasons, it might disrupt the hot air you should be getting in your vehicle.

What Are the Signs That Your Heater Needs Fixing

To quickly fix your BMW’S heater before it escalates, you should be able to read the early signs that your heater might be malfunctioning. Some of these signs would be discussed below.

  • The first and most obvious sign is that your BMW is not releasing hot air into the cabin of your vehicle.
  • You may realize that the heater is releasing cold hair while the engine is overheating.
  • Often a faulty heater is accompanied by a leaky coolant. A leaky coolant could fill your car with a sweet smell.
  • A foggy window can be telling of a heater problem. What we mean by fog is a thick mist covering not one but all of the car windows. This is caused by warm coolant leaking into the cabin and interacting with cold hair which produces warm condensation.

It is important to act upon these signs as soon as you notice them.
