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.....

      Hey guys! Thanks for the feedback!    it’s got some basic mods currently but it’s been tastefully done  has a z32 Maf and a HKS Mushroom filter an old logo nismo strut brace, splitfire coil packs, braided turbo lines, turbo smart boost controller, walbro 450 fuel pump, sports cat and a reinik cat back exhaust, shock works coilovers, Greddy turbo timer, blitz FMIC, blitz BOV, hard race hicas delete, ebc brakes (front), excedy heavy duty clutch, Michelin pilot sport 4 tyres, and the 33 GTR wheels from memory. i have also had my mate 3D print a gas cap holder for inside the petrol flap haha but she’s very clean underneath (being a paint sprayer of 15 years I did not want to mess around with rust!) and she’s had thousands spent on maintenance over the last few years, she drives like a new car!  my future plans is to do an RB30 rebuild with a 25 head uprated turbo etc etc I’m hoping to start this next year, I’ve just opened a premises for my business so that takes priority at the moment! But overall I’m extremely happy with it!

      I'm just being rude. The VQ was developed by Nissan Japan, but it comes from the time when Renault were....ruining what Nissan had been before. Just look at a Nissan Tiida, and tell me that you're not looking at a Renault. In fact, just look at a V series Skyline or Z33 etc and tell me that you're not looking at something Frenchified. I just see the VQ an emblematic of that. It is also a nasty sounding thing. I'm really glad I chose to stay RB and not put a VQ30 in when I did my car. As to the RB30 being Aussie.....arguably it's a bit Aussie.

      That depends, if the French got it from the Japanese, its Japanese. Or, is the rb30 aussie? Also, wouldn't it be Vq for a junior variant?

      As soon as the MAFs are replaced with ones that work properly, if the harness isn't ruined it should run perfectly immediately.

      Is there a good place to learn how an engine works online?

      By luke gtr · Posted

      If you haven't already decided on a career, look at being a mechanic, engine reconditioning or mechanical engineering. All 3 will give you different views and levels of knowledge (eg, mechanic is general for the whole vehicle, reconditioning will teach you engine specifics, engineer can design stuff). Or.......find something you love doing, hope its a well paying area and pay someone else to build the car for you. After 20 years of mechanicing, I've lost the passion for working on my own car. It may be different if I had access to a hoist, but it is what it is.
