Toyota Corolla Cross: Compressor Solenoid Circuit Short to Ground or Open (P06A014)
DESCRIPTION
In this circuit, the compressor with pulley assembly receives refrigerant compression demand signals from the air conditioning amplifier assembly.
Based on this signal, the compressor with pulley assembly changes the amount of compressor output.
