350z Aircon Problem
350z Aircon Problem
Ok so i have had the car over a year now and went to get the aircon checked and re gassed as it wasnt very cold
anyway they regassed the system however the temperature wouldnt drop to a low cold
Any ideas as to what it could be or where to start looking for a fault car was garaged for half the year every year by the previous owner....
I thought as part of the regass they put in UV dye so that inthe event of it not performing as well after, its easy to spot where the leak is?
(thats what was done with my aircon service recently), pressure tested, old refrigerant out, etc etc.
First port of call would be back to the outfit that did the regass..

Possible the expansion valve that controls the expansion of gas when it changes state from a high pressure liquid into a low pressure gas
it appears that the air con is working but simply can not produce ice cold air, so I am guessing that rules out the magnetic clutch because that is a simple on/off.
The pressure sensor is also an on/off operation but rabs can feel some cooling effect so that could prove those two items are working
Going deeper now it could be even the thermistor that is freezing up and switching off the magnetic clutch prematurely, this could be caused by something simple as too much refrigerant in the system.
I am guessing that the 350Z should have some sort of on-board diagnostics for A/C operation,
Have you changed your stereo/cd player recently and do all of your dials/speedo work OK?
HI Guys ok so i have a garage that i trust looking at the car they have had an aircon specialist out to investigate the problem and his finding are as follows
Compressor seems fine clutch is activating but there is no live at the compressor, apparently there could be a release valve that is stuck and thus not allowing the current to get through ?
i had the Rad fans changed last year due to them failing is there a connector that could have been missed when fitting these etc
the local nissan dealership which the garage know quiet well have said (it could be anything best send it down for us to look at) not really up for that as they will charge a fortune yes ok it will get the thing fixed but if its something simple there not gonna let me know its something simple and still charge me a fortune
so looking for a bit more input from you guys can anyone offer advice ?
