The system protects the compressor by not allowing it to run if the refrigerant is too low. Search for "bubbles" and "sight glass" for a method to check refrigernat level. I have a steady stream of fine bubbles in the sight glass. charged with 36 oz. of freon. Could it still be to low on charge? "Fine" bubbles just enough to make the sight glass opaque? Transitions from empty to obvious bubbling and then to "fine" bubbles, just enough to make the sight glass look grayish..? Turn the blower speed down to the lowest level which should reduce the rate at which the refrigernat is exhausted, used up, and see if the sight glass now trnasitions to liquid. If so more charge is needed. But be aware that the compressor may cycle off quickly due to high pressure limit with little "use" of the refrigerant. Is there a certain high and low preasure reading? I have 45 psi on the low and 170 psi on the high at about 75 deg ambient temp. Good readings insofar as I know. Why are we pursuing this line? Because your compressor runs continuously? That may be somewhat normal depending on circumstances. pursuing because my compressor runs for about 10 seconds and then shuts off giving me the blinking green light.

I have a 1990 ls 400 with new ac compresser and i still have a blinking ac light. I can jump the compresser and it cools just fine, could this be a relay?
