Does someone know where the low side AC Service port is located on a 1999 Ford Expedition 5.4?

Thanks

 

On the accumulator, passenger's side of the engine compartment underneath the bulkhead wiring harnesses.

 

You should always get your AC service done by a reputed expert only. A few things you can also do yourself at home to assure the good working of your AC unit. A regular dusting of your AC vents several times a year is a must. Always check if something is blocking your AC's condensing unit.
