Mercedes Sprinter 2018 - Heating, ventilation, air conditioning
The HVAC system (heating, ventilation and air conditioning) in the Mercedes Sprinter III provides the necessary interior comfort in both cold and warm weather conditions and supports a clear view. Regular maintenance of elements such as the heating, air conditioning or ventilation unit is crucial for continued reliable performance.

Mercedes Sprinter III: Heating not working
If the heating in the 2018 Sprinter is not working properly, this can lead to insufficient interior temperature or no heating effect at all. Common causes are a faulty thermostat, a blocked heat exchanger or problems with the heating control valve. Regularly flushing the cooling system and checking important components play a key role in preventing faults and maintaining heating performance.
2018 Mercedes Sprinter - position of the heating control valve
The heating control valve of the 2018 Sprinter is normally located in the area of the bulkhead, directly in the coolant pipe that leads to the heat exchanger. Its task is to control the flow of hot coolant. If this valve is defective, this can lead to irregular or non-existent heat dissipation. Replacing it with a suitable spare part restores the correct function of the heating system.
Problems with the heating in the Mercedes Sprinter III
Common reasons for heating problems in the Sprinter III are low coolant levels, air build-up in the cooling circuit or a defective blower motor. Typical symptoms are delayed heating of the interior, uneven heat distribution or weak air flow. Bleeding the system and replacing worn components usually resolves these problems.
Heating not working (only cold air coming out)
If only cold air is coming out of the nozzles, this is often due to a faulty thermostat, a blocked heat exchanger or a defective actuator for the air flaps. The problem can usually be solved by cleaning or replacing the heat exchanger and checking the mixing flap mechanism.
Failure of the air conditioning system in the Sprinter III
The air conditioning system in the Mercedes Sprinter III can fail if, for example, refrigerant is leaking, the compressor is damaged or there is a fault with the pressure switch. Signs of this include poor cooling performance, unusual noises or the lack of any reaction when the air conditioning system is switched on. To rectify the fault, first check the refrigerant level, compressor and pressure switch. Regular maintenance, including topping up the refrigerant, will keep the air conditioning system in perfect condition. Less text
