ISSUE
Some 2010 F-150, Expedition and Navigator vehicles equipped with 5.4L engine and built on or before 12/15/2009 may exhibit A/C pressure relief
valve discharging. This may be caused by the engine cooling fan motor strategy at idle, resulting in insufficient air[low across the condenser.
ACTION
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
1. Inspect the A/C compressor pressure relief valve for signs of discharging. If there are signs of discharging, then evacuate and recharge the system to
establish proper fill, refer to the Workshop Manual, Section 412-01.
2. Reprogram the powertrain control module (PCM) to the latest calibration using IDS release 67.06 and higher. This new calibration is not included in
the VCM 2010.5 DVD. Calibration files may also be obtained at the website.
