A/c issues.

I got a report from my dad about my 91 zr1. My dad took it out the other day and the Ac was working fine. But then it started getting warn so dad moving it from auto to recirculate but still warm. Then he said the green light started flashing and what ever setting he put it on the light would flash and it wouldn't cool. Any ideas I'm a few thousand miles from home and I don't know what to tell him?
