My A/c was cold but I felt it took a little too long to get cold. I thought I was being too **** but since I have access to a shop I went ahead and checked the system. I noticed I had a small bubbling action at both valves when the caps were removed so I replaced the valves. I recovered .61 lbs of Freon. Total system charge should be 1.44 lbs. I vacuumed and leak checked. I failed the leak test. It appears to be very small. I did not notice anything wet. I did see that someone soldered the condenser at some point but it was dry. Are there any common places that are known to leak?

2000 i30 here.

 

Nope, not that i know of, ive owned a 95.99 and 00 and thats one thing i give nissan! they NEVER EVER gave me a single issue even at 268k miles i never did ANYTHING and she was ice cold no matter what!

only thing is the ac compressor clutch bearing noises that will last for ever but are annoying. so you gonna have to put some dye in the system and inspect.

 

Yeah it has dye in it. Seems like a small leak because it went from -30 psi during vaccum to -10 psi. I was amazed at how cold the A/C was considering it had less than half of what it should of freon-wise.
