Code B048C Chevrolet Description
The relative humidity sensor measures the relative humidity on the compartment side of the windscreen. It also detects the temperature of the windscreen surface on the compartment side. Both values are used as control inputs for the Heating, Ventilation, and Air Conditioning (HVAC) Control Module application to calculate the fog risk on windscreen compartment side and ability to reduce fuel consumption by decreasing A/C compressor power to a minimum without causing any fog. The sensor will also enable partial recirculation mode in order to improve heat-up performance of the passenger compartment under cold ambient temperature conditions without the risk of mist build-up on the windscreen. The humidity sensor element temperature sensor supplies the temperature of the humidity sensor element. It is only needed if the thermal contact between the humidity sensing element and the inside windscreen surface is not sufficient.
