Air conditioning 1985 300 SD

My airconditioning system (R-12) does not cool at all. With gauges hooked up, at idle with clutch engaged, I have 5# on the LOW side and 75# on the HI side. With an increase in rpm, LOW side goes to MINUS 5 and the High side to 100#. The system appears to be full of Freon and will not take any additional when opening the valve. Are these indications of a bad expansion valve, or bad valve AND compressor??

Thanks, Bill
