7B-39 Air Conditioning System: 3 Position sensor power supply circuit check ignition switch turned OFF. 2) Measure voltage between “RED/WHT” wire terminal of temperature control actuator connector and vehicle body Is voltage 4 – 6 V? Air intake control Go to Step 4. 4 Position sensor power supply circuit check ignition switch turned OFF. 2) Check for proper connection to HVAC control module connector at “G52-14”, “G52-13” and “G52-23” 3) If OK, measure resistance between “RED/WHT” wire terminal of air flow control actuator connector and “G52- Is resistance below 5 Ω ? Go to Step 5. “RED/WHT” wire open 5 Position sensor power supply circuit check of air flow control actuator connector and vehicle body Is resistance infinity? Go to Step 6. “RED/WHT” wire 6 Position sensor power supply circuit check air flow control actuator connector and vehicle body Is voltage 0 V? Go to Step 7. “RED/WHT” wire 7 Position sensor signal circuit check switch turned OFF. 2) Measure voltage between “WHT/BLU” wire terminal of air flow control actuator connector and vehicle body Is voltage 4 – 6 V? Go to Step 11. Go to Step 8. 8 Position sensor signal circuit check ignition switch turned OFF. 2) Measure resistance between “WHT/BLU” wire terminal of air flow control actuator connector and “G52-23” Is resistance below 5 Ω ? Go to Step 9. “WHT/BLU” wire open 9 Position sensor signal circuit check of air flow control actuator connector and vehicle body Is resistance infinity? Go to Step 10. “WHT/BLU” wire Step Action Yes No |
