The common leak is the compressor's body seals and shaft leaks in many of the vintage. Most came with green UV dye new. Check for oilyness or dye for the likely leak.
As HT said - running low on charge will not carry necessary oil and burn out compressor even if that wasn't the problem! If you charge - don't over do it! More is NOT better so watch your #s and for dual air systems run front only for more dependable #s IMO and observations.
More: If this is an OE Delphi - check out Sanden's drop in clone NEW not a rebuilt if that's the issue. If compressor wipes out it takes out condenser with it so acting fast to fix this will save $$ and headaches,
