We recently serviced a 2014 Hyundai Xcent at our Motofyx workshop, which had issues with its car AC. The problem was that the AC airflow would get blocked after continuous highway driving, especially during long drives. Although the AC cooling remained unaffected, airflow would only resume normal functioning after turning off the AC for 5 minutes, repeating the cycle.
Our technician suspected ice formation in the AC system, blocking airflow. Detailed inspection revealed the car's AC service was overdue, and the evaporator coil was severely clogged, requiring replacement. Since it hadn't been changed in 4-5 years, cleaning risked damage and leakage.
The primary culprit was the faulty thermistor sensor, causing ice formation in the cooling coil and restricting airflow.
Function of AC Thermistor Sensor:
The AC thermistor sensor monitors the evaporator coil's temperature. Once optimal cooling is reached, the sensor signals the compressor to disengage. When the coil returns to normal temperature, the sensor commands re-engagement, preventing ice formation and maintaining consistent temperature.
Solution:
Removed the entire dashboard assembly to replace the coil and sensor.
Installed new Hyundai genuine cooling coil and thermistor sensor.
Topped up compressor oil.
Performed AC gas top-up.
