B048D CHEVROLET MeaningThe Heating, Ventilation, and Air Conditioning (HVAC) Control Module sends a Pulse Width Modulation (PWM) signal to the electrical auxiliary heater, if the interior temperature is too low and additional heat is requested. The request signal from the HVAC control module, battery positive, ignition and ground circuits enable the electrical auxiliary heater to operate. Through the signal circuit the electrical auxiliary heater sends via a PWM signal the current status to the HVAC control module.
