•Air Mix Actuator system fault
• A/C unit air mix door fault
Shake the wiring harness and conn ectors while performing the inspection to di scover whether poor contact points are the
cause of any intermittent malfunc tions. If there is a problem, check to make sure connectors, terminals and wiring harnesses
are connected correctly and undamaged.
Symptom (6)DescriptionPossible Cause
Windshield fogged. • A/C compressor does not
operate while airflow mode is
in DEFROSTER or HEAT DEF
modes
• Air intake mode does not change to FRESH while
airflow mode is in
DEFROSTER or HEAT DEF
modes • A/C Module (B+ signal) system fault
