Hey there, thanks for the question.
Are you saying the low side is almost 100 PSI when the compressor clutch is engaged??
the compressor must not be turning on, apply 12v to the compressor wire and make sure the clutch engages. Let me know if the pressure drops substantially.
It's not uncommon to see high pressures on the low side with the compressor off, but when it's running it should be a third of that.
