Low Port on A/C system?

Hey guys quick question, is the low port for the A/C system on the accumulator by the firewall on a 2000 Expedition XLT 5.4 with rear air?
Thanks ~Gage~

Check your condensor and make sure there is nothing blocking the air flow, also check your cabin filter and make sure that it is clean.

I have read that it is behind the glove box but I am not exactly sure, I have changed one on my VW Jetta and I had to remove the plastic underneath the passenger wiper and it was underneath there. Check behind the glove box first or search the forum yours may not even have one. If I get more information I'll post a reply. Good luck.

What pressure were you reading on the low side port with truck running and AC on high recirculate, ( 35 to 40 psi )

cbradford the PSI is at around 35-38. The A/C does work but it takes a while to cool down.
Thanks ~Gage~

Supposedly, that was a dealer-installed option; Expy's did not come with it from factory.
