I changed the radiator and some A/C hose on my 2010 G37 i know the a/c was empty and i went to my garage to refill the A/C gaz.
The problem is the A/C compresseur does nt turn result is no cold air !
do i need to do something special to reset the A/C control ?

 

i did another test, i ve conect 12V on the compressor clutch wire and it works . but still won t work by it self .....

 

Could it be that it can sense when the pressure is not within spec and not turn on? I know when I filled my maxima up and overdid it, the compressor would not turn on and when I released some pressure from the ac it would kick on.

 

you are maybe right i ll try another A/C shop, i hope this will solve the problem !

 

sorry if this is a dumb Question BUT why would you replace the rad and a A/C hose!!!u have a 2 year old car at the most? and shouldnt the dealer take care of this ????

 

He's rebuilding a salvage title car.

 

Any update on this?

 

i ve try with another A/C shop and still not working !
when i tried to manualy give 12 volt on the compressor the clutch kick on after 15 second running i saw a lot of smoke coming near the hose on de condenssor.

yes it s a rebuilt salvage car, i ll try to solve the probleme for the lowest cost as possible cause this car is for my girl friend i don t want to pay 100$/hour at infiniti dealer .does any body else have an idea about the problem ?

Thanks for help !

 

AC in our car is very sensitive , if small problem anywhere in air circulation ; all system fail , so you have to ckeck it step by step.

A/C Dryer , A/C Expansion valve and and compressor , my advice you buy all new (since you have rebuilt salvage car).

After fixing them you have to check the AC air lines by filling it with air , then wait for 30 mins , if the air pressure remain same you dont have any leaking prroblem.

Then electric ; you have to be sure power is there (wiring , fuse and sensor).

After you do all of this and filling good brand light freon gas (I am assuming the Condenser is ok) the AC should run.

DONTforget this : there is damn small sensor that control on/off AC attach to the evaporator (behind the dash) it should be there otherwise your AC will be working untill damage.

I hope this could help you little.

 

i looked in the ipdm e/r for fuse , and it was ok,
after i tested the continuity on the terminal between compressor and ipdm e/r, continuity exist .
i tryed to replace ipdm and nothing changed.
finaly i did a self diagnostic on the car i during the test i saw the clutch is working.
but it still not working when i turn the A/C on.

My conclusion is : the compress is ok , clutch magnet is ok, wiring is ok .but something tells the computer to not turn on the compressor ! I can t solve this problem !
