SUBJECT:
Windows May Begin To Fog When The HVAC Is In Floor Mode
OVERVIEW:
This bulletin involves flash reprogramming the Body Control Module (BCM) to increase the amount of air coming out of the defroster ducts when operating HVAC in the Floor Mode.
MODELS:
2001 - 2004 (JR) Sebring Convertible/Sebring Sedan/Stratus Sedan
SYMPTOM/CONDITION:
The vehicle operator may experience window fogging in certain climate conditions when operating the HVAC system in the Floor Mode.
DIAGNOSIS:
If the vehicle operator describes the above Symptom, verify the heater and defroster are functioning properly and that the vehicle operator is using the Fresh Air Mode NOT the Recirculation Mode. Explain to the vehicle operator the condition can be corrected by operating the HVAC system in the Fresh Air Mode with higher blower speed and temperature settings and selecting either the Floor/Defrost Mix Mode or Defrost Mode. Otherwise, the HVAC system can be recalibrated to provide more air flow from the defroster ducts when the Floor Mode is selected. Perform the Repair Procedure if the vehicle operator prefers to have the HVAC recalibrated.
