On the factory r134a, the Low Pressure switch works between 23psi and 45psi.

This year my '93 940 compressor runs but the clutch doesn't seem to cycle off. Must be I have enough pressure to close the LP switch to get the clutch, but the low side pressure doesn't make it up to 45psi for clutch cycling.
