83-603 of the service cd "testing the acc with an impulse counter" to read stored fault codes....also 83-604 "checking elec components of the acc".

Also tape up the outside inlet grilles (around monowiper) with wide 3M blue painters tape following with towells and run a/c, this will tell you if you have a blend/flap issue along with 83-603.

On my 1993 fault (same symptoms as yours) code 30 (aux water pump ground fault) keeps comming up.

Do not be so sure it is a refrigerant or vacuum pod problem, it could be an electrical problem. Be sure before you mess with vacuum pods/dash removal or refrigerant.
