HOOT OR WHISTLE NOISE FROM REAR A/C SYSTEM

 

FORD: 2005-2006 Expedition
LINCOLN: 2005-2006 Navigator

 

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.

ZeroR® AC Refrigerant | R134a Replacement | 6 Cans for AC Recharging
  • UNIVERSAL - ZeroR AC Refrigerant is a hydrocarbon that safely bonds with chemicals like R134a, R1234YF and R12. We can only advertise this product to be used in R134a systems due to EPA regulations in the USA on both R12 and R1234YF systems. EPA also prohibits mixing refrigerant types. See the description for all legal disclaimers.
  • EASY - This product installs just as easily as any R134a products. Cans even have R134a threads and the majority of R134a can taps will work for these cans.
  • 6oz CANS - Refrigerants are compressed gasses and are measured by weight, not by liquid volume such as water. All gasses compress differently and produce a different weight. ZeroR AC Refrigerant is low weight compared to R134a, but its performance is equal to 16oz of R134a.
  • ECO FRIENDLY – ZeroR AC Refrigerant is a 100% Natural gas unlike R134a, R1234yf and R12.
