Hello,
I have a 2011 G37x sedan and I want to inspect the ac amplifier module. The part number is: 27760-1nn3a. I was wondering where I can find a schematic of the printed circuit board that is located within it.

 

AFAIK, it doesn't exist online- at least not for the masses. That is likely considered "proprietary" by both Nissan and Calsonic Kansei (the halfa** manufacturer of those- and most- modules).

I think you'll have better luck finding the needle in the haystack but others may have more input. If you, or someone you know, is a member of gtrlife.com, forum member Legertas might have some input as he knows Nissan electrics quite well.
