Default Removing air box

Hey all,

Got another question. The A/C is almost non-existent on both sides now and I'm trying to remove the air box so I can get to the low-pressure port. I've removed the 2 thumb clips for lack of a better term and the two screws on top. Also I loosened the hose clamp but for some reason the air box isn't coming out. Obviously I've missed something and given that the PCM is right below I don't want to break anything. Is there a tip to getting it out or did I miss some clips, screws, etc?

Sorry for the noobish question but I DID search and didn't find anything. Running on little sleep and being in the car quite a bit w/o AC is rotting my brain.

Not sure if the 3.8L is exactly the same, but my 06 3.5L has 4 snap in clips that all need to be pushed in at the sametime and then the upper part of the box comes off..Then only the lower part of the box will remain, which holds the PCM, so then unclip the PCM, and the lower part will pull out. My lower tray is held in by a press fit into rubber grommets, but no screws...I hope this helps for your car...

Air box issue was resolved by a good night's sleep and looking at it with a good light source...doh!

Anyway if someone could please confirm where the low side port to add refrigerant is on the 02 SS I'd be extremely grateful. It appears as if its located below the driver's strut brace, but none of the AC refiller nozzles work on that. Only thing that happens is the refrigerant gets sprayed onto the hose and body since it won't seal correctly. Could some kind soul give me some direction before I lose what little sanity I have?

Edited in: Just wanted to note that the AC recharge kit I bought plus another hose with just the puncture on one end and the quick coupler on the other have the same issue. I was able to connect to what I BELIEVE is the high side port on the firewall and see 70 lbs of pressure with the A/C on max.

Thanks in advance to anyone who can lend some help here.
