While the Mercedes Sprinter's heater can experience various issues leading to failure, a significant factor often involves problems with the heater blower motor assembly, such as issues with the blower motor or resistor. Approximately half of all heater failures are attributed to these components. Another common cause is a malfunctioning thermostat. Additionally, problems may arise with the heater control valve, heater hoses, or the blower motor itself. If you notice that the heater is not functioning, consider whether the fan is also affected. If the heater is only blowing cold air, the problem might be related to temperature regulation, whereas if the fan itself is not working, a mechanical issue is likely to blame.
Hello everyone. I own a 2014 Sprinter van and the heater motor is not functioning. I replaced the motor with a new one but it still does not work. I then replaced the climate control button unit but the issue persists. I am seeking advice from experienced professionals. Can any of you offer me some professional guidance? Please feel free to reach out to me at rmerss@gmail.com. Thank you.
If the heater isn't functioning properly in your Mercedes Sprinter, make sure to inspect for issues such as a malfunctioning heater blower motor, thermostat malfunction, or faulty heater blower motor resistor.
I'm curious if you were able to find a solution.
