ISSUE
Some 2004-2005 Expedition/Navigator vehicles built between 04/01/2004 and 9/26/2004, may exhibit a hoot or whistle noise inside the passenger
compartment, coming from the A/C system. The vehicle may also exhibit insufficient A/C cooling. This may be due to low A/C refrigerant charge from
the factory.
ACTION
If normal diagnostics do not point to a system leak, evacuate and recharge the A/C system. Charge the system to 40 ounces for systems that are not
equipped with rear A/C, and 58 ounces for vehicles that are equipped with rear A/C. Refer to Workshop Manual Section 412-00 A/C system leak
diagnostics and system recovery, evacuation and recharging.
