Year: 2005
Make: Nissan
Model: Pathfinder
Engine Size: 4.0
Refrigerant Type: R-134

My 2005 Nissan Pathfinder developed a leak in the rear AC lines. From what I read on the internet, it seems to be a common problem with this model. The lines corrode under a protective metal plate where road salt lays on the aluminum pipes. I have a leak in both the high and low side. I need to know if this is repairable. In order to replace the lines, the body has to be lifted off the frame a little bit, and I would really not like to go that route.
My question is if anybody knows of an AC repair shop in the NY metro area that can handle this repair and do it right. I don't want a temporary fix that will leak out wvery year.
Thanks in advance for any help and sggestions.

The real fix is to replace those lines-- although I have been known to use swageloks on them--- just google swagelok

The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
