'99... A/C doesn't seem to be getting very cold. Compressor is kicking in and there's some cooling, but not much. So, I figure I should check the pressures, try the quick and easy re-charge as a first option if it's low and see where it gets me, look for leaks later :-)

First question: Where's the high pressure fitting? The low pressure is obvious enough but I didn't see the high pressure fitting.

Second question: What are the usual pressures in this car low/high, and with compressor on.

Thanks,

 

in my 95 the high pressure is on the same side as the low but closer to the radiator and the fitting faces the back of the car

 

If your going to do the charge in a can, you don't need to tap into the high side.
Get a charge kit with a gauge & hose, charge on a warm, not hot day through the low side until the idiot gauge indicates the system is full. (usually a green area on the idiot gauge).

 

I usually like to at least see the pressures on the high side as the compressor comes on and off so I have a clue what's going on. Makes me feel good to see it in the right ranges :-)
