Low side should be about 30 psi, high side 150 to 300, depending upon outside temp and fan efficiency. If low and high pressures are the same, the compressor isn't operating.
With the engine running and AC on, visually check the center of the compressor clutch - if it isn't turning, the compressor isn't turning. Many possible reasons for the compressor clutch to not be engaging...
