Modern vehicle climate control is shifting from simple mechanical components to complex, networked electronic systems. This comprehensive seminar provides automotive professionals with essential knowledge to help diagnose and repair both traditional internal combustion engine (ICE) and advanced hybrid/electric vehicle (HEV/EV) HVAC systems. We will discuss the critical sensors (the system's inputs) and actuators (the system's outputs) that govern cabin temperature, humidity, and airflow, equipping you with practical, systematic diagnostic techniques using multimeters, oscilloscopes, and scan tools.

Additionally, we’ll explore the unique challenges of electric vehicle thermal management, which is crucial for maximizing battery range and longevity. You will learn the operation and analytics of components like electric A/C compressors and Positive Temperature Coefficient (PTC) heaters.

Key Seminar Topics

• Standard HVAC System Inputs: Detailed study of temperature, pressure, sun load, cabin air quality and humidity sensors.

• Traditional HVAC Outputs: Diagnosis and calibration of blend door actuators, blower motor control (PWM), cooling fan technologies…
