[KimberlyMarie]

The air conditioning filter of the Mercedes-Benz S-Class is located behind the glove compartment. Specific reasons: Lack of antifreeze used by the engine, the engine's antifreeze reaching the replacement cycle, damage to the engine thermostat, excessively dirty air conditioning filter, or blockage in the vehicle's circulation system, among other reasons, can all cause the vehicle's heating system to not produce enough heat. Solution: When the heating system of the vehicle does not produce enough heat, you can inspect the vehicle's heating system using a troubleshooting method. After identifying the specific fault, carry out the corresponding repairs. If any parts cannot be repaired, they should be replaced directly. After repairs, the vehicle's heating system will return to normal operation.
