Would the low refridg cause the a/c compressor to not engage even after jumping the pins.
I'm not sure what pins you're jumping. I never had to jump anything in a Cadi to start the comp. Clearing the ACM codes will turn on the comp during a recharge if the system is operational.
Clear the ACM while it is running. Turn AC on while someone is watching and/or listening for the comp to come on.

Re: 1999 Eldorado
Maybe the compressor clutch is shot. Try putting 12v directly to the clutch, but with the LOW REFRIGERANT message I suspect that is the problem and you are somehow missing it. Have you put a set of A/C gauges on it to get the system pressure readings?
I edited your title. "1999 Eldorado" is not very informative.
