You will want to take it to a shop that will determine WHERE the leak is.
This spring....I had my first A/C issue with my '96....at 183K miles.
I took it to my indepenant shop.....and they used a "sniffer" to check for leaks around the compressor, etc....and could not get any reading of a leak.
The recharged the unit with a leak detection dye in the charge.
Told me to come back in a couple weeks....as it was still cold outside......
They looked.....and found that the leak was from the evaporator coil.....which is inside the passenger compartment.....not a fun job for them to replace.

My point being...find the leak location before replacing anything......my compressor was fine......and did not need replacement....and would not have done anything to cure the problem.
It is possible that it is only a seal at a pipe/hose fitting.....(I like to hope for cheaper solutions first).


They also had to replace the relay that engages the A/C compressor clutch.....as it would not stay engaged.....but that was a separate problem from the leak.....very likely caused by the constant cycling caused by the low charge of the A/C system.
