Rear Air Conditioning Inoperative, Blowing Warm Air
Condition Some customers may comment that the 2nd row / rear HVAC blows warm air when air
conditioning is commanded
Cause - This condition may be caused by the auxiliary temperature valve, internal to the A/C
distributor case, being fractured.
Note: The technician may find the pivot for the temperature valve has pulled away from
the actuator motor (2).
Verify if the temperature valve is working properly:
• If it has been validated that the rear A/C does blow warm, replace the A/C distributor case.
• If the temperature valve has been found to be working correctly, refer to SI for further
diagnostics.
