Driving around an older model BMW through Toronto and the surrounding areas can sometimes be a bit of a burden, especially when the temperature outside is brutally cold. If your car’s heat is not as warm as it should be, you could be suffering needlessly.
Your BMW’s heater core is a small radiator like unit that’s situated between the engine compartment and your dashboard. It’s most likely situated behind the dashboard and it does have a specific life expectancy. Eventually, it will begin to break down and no longer generate the type of heat you have grown accustomed to.
Many of these heating cores can become clogged or damaged due to a variety of factors. When more of the fins become clogged, the coolant or antifreeze that moves through the engine and then through the heater core on its way to the radiator is not going to be dispersed properly. In other words, it won’t generate enough heat to keep the main part of your BMW warm.
Some signs that your heating core needs to be replaced.
If you’re driving around and have the heat on full blast, but are only getting lukewarm air, it may be due to a worn-out heating core. If you turn on the fan and nothing comes out, it’s more likely the blower.
No matter how old your BMW is, replacing the heater core or even the blower can be a tremendous job. It doesn’t have to be all that tough, though. Bring your BMW into an authorized BMW service center to have the system diagnosed. It may very well be a minor issue, such as a blown fuse, but if the heating core, the blower, or other major components need to be replaced, it’s best to have it done as soon as possible rather than trying to deal with getting around the city while freezing at the same time.
