Cleaning the Cabin Temperature Sensor

Model: Mercedes Classe C - Years 1983-1993
Part: Checks and maintenance

Depending on the internal cabin temperature and the external temperature, the air conditioning system regulates the temperature of the cooled air: it is essential that both sensors function properly to ensure optimal climate control; the external temperature sensor is generally located in the front bumper grille while the internal sensor is in the cabin light fixture; to ensure it works correctly, clean it with contact spray but you need to remove it by detaching the light fixture from the headliner, then disconnect the sensor harness and the sensor itself.
