If the heater and AC are only blowing hot air regardless of the temperature setting, it could indicate a malfunctioning thermostat, which may be stuck in the heat mode. Another possibility is a problem with the blend door actuator, which controls the mix of hot and cold air. Additionally, low refrigerant levels or a failing AC compressor could also lead to inadequate cooling. Lastly, issues with the climate control system's electrical components could prevent it from operating correctly.
