My passat A/C doesn’t work when the car sits still for a while. If I am moving anything over stop and go rushhour traffic it works fine. Does this sound like the Compressor, or just in need of a re-charge? The car is a 2001 and it sounds to me like it’s re-charge time.
dimished airflow over the radiator + compressor rotating at reduced speed (idle) = poor heat exchange. I have never had a car that had good ac while stationary.
True, but this is worse than normal. With any normal A/C setup there is at least some cooling when stationary, with this there is none at all, but plenty when moving.
