As an owner of a Mercedes Benz, you understand the superior level of comfort, style, and luxury that these vehicles possess. Mercedes embodies intelligence, sophistication, technology advancement, and renowned safety features. While these automobiles are in a class by themselves, they are still susceptible to mechanical errors or malfunctions, such as a heater blower motor malfunction.
Optimal comfort is one of the characteristics that make a Mercedes so appealing. When this comfort is compromised, it can create a negative driving experience. Climate control in the cabin of your vehicle is maintained through the HVAC blower, so when the blower motor is malfunctioning, the temperature may not be regulated to your comfort.
Possible Causes of a Heater Blower Motor Failure
Your Mercedes may experience a blower failure for several reasons. Determining the cause of such failure must be done in order to diagnose then successfully repair the problem. This process is best performed by an expert mechanic who has the knowledge and expertise to work with these European made vehicles.
Like any automobile, with age comes normal wear and tear of the components. The more you drive your car, the greater the possibility of your blower motor giving out. Prolonged use and missed routine maintenance appointments can lead to a blower malfunction.
Another piece of the HVAC system is the blower motor relay. This important component sends the proper amount of power to the blower. At times, the relay may suffer from electrical problems, which can prevent the blower from distributing the proper flow of air or stop the air flow completely.
Overheating of the resistor motor can be a common cause of blower failure as well. This can happen when improper measurements are gathered during the engineering process. This may cause the HVAC blower to stop working, which will need to be addressed immediately for the comfort of you and your passengers.
Questions to Ask When You Suspect Blower Failure
If you suspect blower failure, you may check if the air blowing from the vents is consistent with the temperature setting. A mechanic will begin their inspection by checking to make sure the unit is blowing cold air when the air conditioner setting is utilized and hot air when the heater is used. Of course, these two settings should feel very different when things are working properly. If the two temperature settings are not distinguishable, you could have a coolant leak. While a blower failure may not cause this issue, it can create an extremely bothersome interior climate and should be addressed immediately to ensure a comfortable drive.
Next, check to see if the air is flowing out of each vent inside the vehicle. The answer to this question should be quite easy. A simple test can confirm the results. Switch the air control knob to the strongest setting, pausing at each interval. Make sure that the flow of air gradually becomes stronger as you increase the settings and make a note of the air blowing from each of the vents. It should be strong, smooth, and consistent. The absence of any airflow at all will signal a serious problem. While this could be an electrical issue, it is more commonly a result of an HVAC blower failure.
