Congratulations on the 348. It does sound like it could be a low pressure problem but could be a couple of different things. Do you know when the last time the car was serviced and the AC system charged? Suggest you first check all the fuses on both the luggage panel and the passanger side panel. Then if they all are OK take it to a specialist for a quick look.bonedoc said:Just bought my first Ferrari today. It is a 91 348ts. The AC sort of works. It turns on when I tell it to, but I can hear the the compressor clicking on and off repeatedly.....every few seconds. What could this be? Relay?
