After installing the underdrives from march on my 95, the car feels better. Definately an improvement, as to a worthy improvement on the dyno, probably not. It was just something to buy and put on the car, nothing more nothing less, power is made with heads cam and an intake, not bolt ons. Anyway, after installing them, the car charges just fine, no problems whatsoever. But, when I turn the ac on, the car immediately drops its guts and is on N or O on the gauge. Granted I don't have definitive, actual electical measurements. I'm considering either the Alt's bad, or the pulley system isn't working well enough. So now, in addition to my charging issues, My AC has decided to RANDOMLY stop going to anything but defrost. It started firstly with the coming out of defrost and dash, then went to feet and defrost, now it's on defrost only. So I'm afraid to turn the AC on for the fact it may loose to much power, and that obviously somewhere vacuum is escaping, so it starts to surge when I turn the car on. I know for a fact my line to the AC is good, I checked countless times. Any ideas?

Put the stock alternator pulley back on and see if there are any changes (for the better)...

The defroster vent problem is common. there is a vacuum line that goes from the driver side vac tree to the passenger side along the fire wall. then it goes into the car. your prob is most likely along the FW. the line is very small. mine was broken right in front of the passenger. I used heat shrink tubing for the repair
