- Incorrect temperature setting: Ensure that the temperature setting on the climate control panel is set to a lower temperature.
- Faulty thermostat: A faulty thermostat may cause the heater to blow hot air even when the temperature is set to a lower value.
- Insufficient coolant: Low coolant levels can result in the heater not receiving enough coolant to regulate its temperature effectively, causing it to blow hot air.
- Malfunctioning blend door actuator: The blend door actuator controls the mixing of hot and cold air inside the vehicle. A faulty actuator can prevent the proper blending of air, resulting in constant hot air flow.
- Faulty heater control module: The heater control module is responsible for regulating the temperature and airflow inside the vehicle. A malfunctioning module can lead to incorrect temperature readings and hot air blowing.
