If after restart the low side has high pressure, this is typical if the compressor isn't running. ( the system will have equal pressures on both sides if it isn't running. )
Your issue seems AC control panel related not mechanical. You should be able to get live data out of the control, anyone know if this is still possible? On my 97 with the system on , press REST until the display changes then use the hot / cold buttons to scroll through the info.
