hey guys,

i have just had my 100k service done, and atm one of the belts is screeching on start up until i give it a rev and it goes away. now i havent had a chance to get back to the mechanics due to work commitments, but i will be as soon as i get a chance. today i went to turn on my aircon and it didnt work at all, no air comes through the vents nomatter what speed u have the fan on. so i tried just normal fan and still nothing. i was wondering if this would be related to the belt slipping problem or totally different problem. it's not the aircon gas run out bcoz the normal air would have still been flowing through when i put the fan on. any ideas before i go to the mechanics?? or even the auto elect.

cheers daz.

Alternator belt? Had the same thing when I took off my alternator to replace it. When I put it back in and started the car, it was screeching and making a hell of a lot of sound. Just tightened it up more and it went away. This would probably have NOTHING to do with the aircon however, perhaps check all the belts, see if they are loose?

the fan that blows air is electric ..... it has nothing to do with the belt

check your fuses .,....

if you can here a fan noise but have no air coming out then .... a few things can happen to stop the air flow .... the ducting is detached or your fan is spining backwards :D

yeah when u press the aircon button, u can hear the compressor turn on but no air comes out, im pretty sure it mite be a fuse for the a/c. and the belt has been tightened now, i didnt think that was the problem for the aircon not working, but it mite have been, so i thought id ask anyway. il see how i go....and il write back in here, its hard when i havent got much time between work to do stuff, but il try.

if your A/C is blowing hot air and sensor's seem ok my guess its your A/c relay!!

happened to me bout a month ago.

to test go to black box in the engine bay where jump points are swap A/C relay for fan relay if A/C starts working there is your problem!!

oh nissan dealership spare parts tryed to charge me $110.90 WTF hahah

i laughed in her face

then went to a wrecker and payed $10

A/C works mint now

well, after dropping my car off at my mates auto electric shop today the traced it back to being what they called the "FAN SPEED CONTROLLER" module. its located behind the glove box, so u have to remove your glove box and it will be in there towards the white plastic bit on the right side.

it will look like this.....

    • There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.
    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful
