I hope the relay fixes the problem. Personally, I'd likely see if the
A/C radiator fan is running after the compressor kicks out before I
replaced the relay.
On the other hand, the relay switches an inductive load, and after
twenty years, it very well might have worn out.

We had an 89 Mazda MPV that seemed to "eat" relays.
A/C relay, Rear defroster relay, relays inside the turn signal module,
electric "kickdown" relay, Overdrive relay, and so forth.
The typical failure mode was contacts heating up, melting plastic, and
then the contacts would not close. No shorts were ever found.
I believe the relay mfr over spec'd the relays in the MPV since the
failing relays were all the same part number, except for those in the
turn signal module, which were made by the same mfr.
