I have a 2006 Escalade(not EXT OR ESV) and need to recharge my A/C system but I cannot find the Low port for the A/C unit anywhere just the 2 high ports.
Anyone know where the low port is on these things?
low should be on the passengers side near the firewall, the hi side is near it.

2 high ports?
No such thing.
One of those is low.
Remove the service caps, the big one is high pressure, the smaller is low pressure.

negative... both of the service ports are on the same line. I, too, am looking for the low pressure service port. I've looked all the way back to where the low pressure line goes into the cabin in the back of the rig and can't find a connection anywhere.

Well, I wouldn't have thought it, but both ports are in the same line. One port is large for high pressure and the other port is small for low pressure. Charged it up and it worked great! The compressor worked intermittently until it was fully charged.
