ISSUE
Some 2005-2006 Expedition/Navigator vehicles built before 1/30/2006 may exhibit a hoot or whistle noise inside the passenger compartment, coming
from the rear auxiliary A/C system. The noise will most likely be heard by the customer when driving the vehicle with the interior cooled down, the rear
A/C off, front A/C on, and the blower fan on the low speed setting.
ACTION
Replace the thermostatic expansion valve (TXV), located near the rear auxiliary A/C housing, following the Workshop Manual procedure (Removal And
Installation: Thermostatic Expansion Valve). The procedure can be found in Section 412-03B of the 2005 MY Workshop Manual, or Section 412-02 of
the 2006 MY Workshop Manual.
