Engine Size: 3.8

I've checked everywhere in the engine bay for a slow leak with both electronic and UV detection and nothing shows. The remaining possibility is the evaporator but I don't see how to access it.
Anybody know how to check it or what parts to remove to get to it?
Number one leak location is compressor shaft seal followed by compressor body o-rings---I haven't seen an evap leak ever on that style W-car-- so are you sure your shaft seal is okay-- I change shaft seals and have never seen a dry one on a V-5 single lip shaft seal application. If you remove your clutch driver- I'll bet the shaft seal is wet and drooling oil- if it is the OEM compressor.
The evaporator change is a dash pull btw.....
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
The Compressor has been completely resealed - tight as a drum :-)
Looks like I'm in for some misery - it's 95 degrees here in FL and no fun tearing out the dash. I'll try putting in some r134 and using the electronic sniffer around the vents.
In my pathfinder I was able to remove the blower motor and directly access the core. I guess there's no such shortcut with this one.........
