I need to fill up the A/C system with more Freon/Refrigerant but want to make sure I tap into the correct line.
My understanding is there are two aluminum lines and the one with the smaller port is the one that the refrigerant needs to go into.
Any online pictures or even descriptions that show where this is?

I can take a pic if I remember when I get back to the car. On the driver side. You have to remove the plastic cover on that edge. Can't miss it. Two alum lines. One with black and another other baby blue caps. The refill can only fit one of those. Can't remember off the top of my head which one

Here's what I did:
- bought a can of R-134a refrigerant/sealant that came with the gauge and hose
- took off the drivers' side cover plate to access the aluminum lines
- the tube only fits on one of the ports, the smaller one
- the gauge read in the "green" (ok) zone but I know it wasn't since it was blowing hot.
- connected a separate gauge and hose to the same port, it read low so I connected the refrigerant to that gauge/hose.
- turned on the engine
- turned on the A/C, fans all the way high, temperature all the way cold
- released the refrigerant into the system, took at least 10 minutes for the can to empty and it's hard to tell when the can's completely empty.
- did the same for a can of stop leak
- put everything back
Blows cold now

My goodness.. your P!G needs a good interior detailing.
One comment - the amount of coolant between RIGHT AMOUNT and WAY TOO MUCH is very small on an R134 system. While it might work fine at some temperatures, an overfilled system can make high enough pressure to trigger the over-pressure shutoff switch, or in extreme cases - pop the pressure relief in the dryer container. To do it right - you really should evacuate all the old Freon (using an EPA approved recycling system) then refill the system by weight.
One question - with the system on HIGH COOL, were both electric radiator fans running full speed? If one of these is acting up (and the small one should run whenever the AC is on) you will get poor cooling from the system.
