Could someone please help me find the low pressure service port on the A/C system? This is a 2000 5.4L Expedition.

The high pressure port sticks right out but the low pressure port is nowhere to be found.

Thanks for the help.

The low side service port is on the accumulator(filter/dryer), which is located on the pass. side firewall.

 

Just in case someone has trouble in the future:

I had to wait until my truck had completely cooled so that I could get my face close enough to locate the port. It IS located where Tailgator specified but there is a bracket with hoses and wire harnesses that block the view and access.

If you'll insert your hand along the path of the top of the valve cover there is just enough clearance to get your hand on the cap for the service port. It hangs off of the side of the accumulator and points toward the center of the engine.

Good luck.
