Refrigerant Type: 134a
Country of Origin: United States
I live in Florida, I have a 1999 Nissan Altima, one owner which is me, this car has not had any type of major mechanical work done yet. The only work done to the car has been new CV Shaft, struts, and that's it. So no one messes around in the motor area or AC lines of my car.
My car has been cooling good since i first purchased it 9 years ago until the last six months, the system seems to have a slow freon leak! The Auto AC shop that I first took my car to they only specialize in auto ac! They kept my car for two days and can't find the leak!!!
They evac the entire system and added the 134a freon back into the system and they also injected the system with a UV to detect where the leak is at. Well Today the car started to throw out warm air which means the system already leaked the freon that i paid for that they added, so i take my car back to them and still they can't find the leak! They used the Ultraviolet Light and Nothing! They used the freon sniffer and still they can't find anything! They even checked under my dashboard to see if the leak is inside the box and still they found no leak!
So, the guy's from the AC shop told me save your money and go to the local auto part store and buy two(2) cans of 12oz 134a and add it to the system since it's empty, well i have done this twice already and the freon only last 4 months in the system.
They told me two(2) 12oz cans is what the system holds.
Today i bought another two 12oz cans of 134a to add it to the system at lunch time. But i was thinking can i add one can of 12oz 134a and another can of the same but with UV ???
The shop already injected the system with UV but it doesn't seem to push it out! or is the UV that they added enough? I was going to add two 12oz cans of 134a one with just freon and the other with the UV??
What should I do???
They told me to keep adding freon till the UV pushes out and they are able to find it.

A leak that bad has to show up in either dye or the sniffer, they may just not be looking at the right place. You can check the front hub for signs of oil or UV dye, all the connections including the service ports for signs of dirt sticking to the oil.. IÃ¢ÂÂm not sure how much room is by the clutch area, but probably not enough to pull off the clutch driver. If itÃ¢ÂÂs not leaking anywhere else, the front shaft seal would be suspect. It can hold a lot of oil and dye before it makes itÃ¢ÂÂs way out to be visible. But you could use something like a shower cap and cover the front of the compressor, let it sit a few hours and then poke the sniffer thru and if the front seal is leaking, it will go off.. You can check with the UV light from Ã¢ÂÂunderÃ¢ÂÂ the car also. Hope this helps..
PS: adding refrigeranbt without adding oil can lead to compressor failure. So find and fix the leak before more damage is done...Hope this helps..
Freedoms just another word for nothing left to lose
