The original refrigerant installed at the factory in 1973 was R12 (Freon). If it has not been converted to R134a, I suggest you convert it now, if it is leaking and needs repair. R12 is no longer in production and the dwindling supply is very expensive. Much cheaper to convert it to R134a.
Your 1996 El Dorado uses R-134a refrigerant.

...it fixed the issue on my 1995 ElDorado, BUT you must disconnect the battery for a little while to reset the computer to allow you to add Freon to the system. I had a leak and it fixed it for about 6 months. Both warnings went away until the system got low again.
Most drivetrain parts and some body parts are interchangeable, the largest issue being the larger bumpers on the '73 vs the '72.
