No, actually I had to replace the high pressure line of my AC system because it developed a pin-hole leak and my freon/refridgerant leaked out. It is my understanding that having "exposed" the system to air then I must replace the system drier/filter. On older cars, it is easily identifiable and normally in a corner of the engine compartment. Nissan has hidden this one and I cannot find it anywhere. I have purchased the replacement (1.5 by 9 inch aluminum cylinder), just cannot find where it goes.
