I have been trying to diagnose the issue of my A/C for awhile now. I know the compressor works fine, relay is good, the system is pressurized. I brought my car to a shop and the dude said the compressor was turning off because of a pressure issue. Does anybody know an easy way to get to the AC pressure sensor without me having to rip the front end of the car apart or remove the radiator/condenser?

 

Removing the front end on a 350Z isn't really that difficult. If it's too much for you, maybe you should take your car to a shop. Otherwise, just follow what's in the FSM.
