I couldn't get my ac to work so i recharged it and it still didn't work so i messed around with it a bit before noticing that the a/c pump is doin anything, i checked the fuse and it was good, but it doesn't seem as if there is power at the relay? anyone have any ideas?

Do you have a pressure gage or a computer scanner? My scanner will tell me the hi side pressure. What is the hi side pressyre?2002 Electron Blue Vette, 1SC, FE3/Z51, G92 3.15 gears, 308.9 RWHP 321.7 RWTQ (before any mods), SLP headers, Z06 exhaust, MSD Ignition Wires, AC Delco Iridium Spark Plugs, 160 t-stat, lots of ECM tuning

I'm not an a/c expert, but to the best of my knowledge the hi pressure switch is used to control when the condenser fan is activated and the low pressure cycling switch(by the accumulator) is used to control the a/c clutch engagement. Try unplugging the pigtail from the low pressure switch and jumping the pigtail while the a/c is turned on at the dash. If the compressor kicks on, then either you have a bad low pressure switch or you actually do not have enough refrigerant pressure to satisfy the PCM. If the compressor does not kick on it could be a bad compessor clutch relay or a short somewhere in the compressor/low side/relay circuit but not as likely. There is also a condenser temp sensor as well.
Another thing you need to do is scan for codes. HVAC DTC's do not activate the SES light.
