Is Your Mercedes-Benz Heater Not Working On One Side? Here's How To Fix It in Glendale

Thus, the heater is an important part of the car that can keep the engine cool. Moreover, the heating system has several components to keep it running such as a heater core, a heater fan, the cooling system, and the HVAC controls. Like the other parts of the Mercedes-Benz, the heater is also not working and causes major damage.

In general, driving a car with a broken heater is always inconvenient and dangerous especially during the winter because the heater is used for removing the ice and fog build-up on the windshield. Moreover, driving a Mercedes-Benz with a broken heater is the biggest safety hazard for an extended period of time.

How the heater does work?

Basically, the heater in your Mercedes-Benz is interacting with several cooling system components such as a coolant, radiator, thermostat, and water pump. During the combustion process, a lot of heat is generated from the engine. However, the majority of the heat goes out through the exhaust system of the car.

But, the rest of the heat is transferred to the coolant inside the HVAC system. In this process, the hot air of the engine is flow from the radiator to the heater core for allowing the coolant to flow through the system which is regulated by the heater control valve.

Once you set the HVAC control panel at the right level, the blower motor is forcing the air over the heater core and into the cabin at the appropriate speed. Due to numerous reasons, the whole heating system is working poorly. So, when the heater is not working, it’s always advisable to consult a mechanic for diagnosing and fixing it.

Reasons behind the failed heater

Like the other components of the Mercedes-Benz, the heater is also damaged over regular use and age. Through proper diagnosis, you can determine the reason behind the damages easily. The following points define the reason behind the failed heater in your Mercedes-Benz.

Failed heater fan

Generally, the heater fan in the heating system is containing a hot coolant for blowing the heat into the cabin. When the heater core is breaking down, you will find that the heat is unable to remove from the engine and cause engine overheating problems.

Clogged heater core

When the outside debris and particulates are accumulated in the coolant system, it will clog the heater core poorly. On the other hand, the rust radiator and when the debris gets through the radiator are clogging the heater core and affect the heater functions. At this point, you have to refurbish the heater core or replace it.

Failed thermostat

Thus, the most common causes behind the failed heater in your car are the broken thermostat. If the thermostat is stuck open or closed, then it will not only affect the functions of the heater but also affect the overall functions of the cooling system. Neglecting it for longer can cause major damage to the cooling system.

Failed HVAC controls

In general, the HVAC controls of the Mercedes contain buttons, dials, shorts, knobs, or feedback touchscreens for triggering the heating system. When the HVAC control parts are damaged like dials, touchscreen, and shorts, it can prevent the functions of the heater and need the immediate attention of a mechanic.

Low coolant/antifreeze

Another common reason behind the failed heater is the low coolant or antifreeze in the cooling system. Due to the low level of coolant/antifreeze, the hot air is unable to reach the heater core for keeping the cabin inside the car cool. As a result, the engine is working very hard to reach its functions which causes overheating problems.

Failed blower motor resistor

Sometimes, the failed blower motor resistor also affects the functions of the heater. When it is failed, you will face problems with setting the speed of the heater fan to get the air out of the engine.

Conclusion

Driving the Mercedes-Benz with a failed heater is always life-threatening. When it stops working, try to fix it immediately.
