Help please: Adding refrigerant to my 06 H3...which port is the Lowside?

[jersey]

Actually, while I was under the hood I noticed I didn't hear the clutch turning on and off. That's odd. If it were low on r134 I should hear it cycling on and off more rapidly, no? Checked fuses but all seem good; I swapped the relays again as I did the week before when the blower resistor malfunctioned, since they're all the same, and even changed the megafuses around and still no cold air. I do see a/c condensation dripping out under the H3, so that must mean something as that was always present. So it seems the problem is with the clutch. If it's not a fuse, a relay or a megafuse, I wonder what could be wrong? Any idea's on what to check next?
