1992 964 Airconditioner turns suddenly off

[boying_r]

My 1992 964 has 21,000 km in it and drives immaculately except for its airconditioner that goes off mysteriously and comes on again after a while, This woud not cause any problem in cool or mild weather but here in our country where it is hot, the inside turns into a sauna when the a/c turns off even foe 5 minutes. I thought it was caused by a defective ignition switch which was suggested by a Porsche mechanic. But after changing the ignition switch, the problem still persists, Anybody's help is appreciated. Thanks

Check Refrigerant gas level, check condensor under battery vent...it gets ruined by that

Thank you. Will try that and get back to you.

I'd get a new fan relay. They tend to overheat with age and start to fail.
