Hey,

Have a little issue with my AC in my r32 gtst and hope someone has an answer.

When i got my ac compressor changed+regassed, the mechanic said that my blend door servo motor is dead. Therefore i cannot control the temps of the ac. He set it manually to cold so I just get cold air coming out regardless of Temp on climate control.

I went into AC diagnostic mode, and went through all the steps and no error came up for a dead blend door motor. ( I think the number is 26 ).

So what exactly is my problem? If it was a dead blend door motor it should have registered on the diag test mode on the climate control...

Cheers

Patrick

Was good during hot says as its stuck on cold but now I cant set it to Hot on the cold days! :)

So the problem is you can't get it to turn off.....

Ask the guy who put the new compressor in to show you where you can turn the air-con off from"manually",,,seeing he

set it on cold all the time...you can set it back during summer.

If he says you can't..he was lieing to you from the start and does not know anything about climate control.

Might then have to try some one who can fix your problem from the start.......how do you know

he correctly diagnosed the problem at the start and that he changed your compressor for no reason at all.

You might have a blown main fuse or something like that...lol

He said that he set the hot/cold flap to Cold setting manually. The climate control controls a motor (blend door servo motor) which moves the flap from cold to hot. He said that the motor is dead and that i should find a 2nd hand one to replace it with, in order to have control of temperatures again.

The funny part is that the AC Diag should come up with error 26-blend door motor, but it doesnt...

I have the same issue with my r32. No hot air comes from the vents what so ever (great in summer, but its starting to get annoying). Running the A/c climate control diag says that everything is working.Anyone know what might be causing this. Is there anything i can do to diagnose whats going on.

Common problem...and AC Diagnostic mode would not necessarily give an error for it...mine didn't because it was a failure in a mechanical component...just go to a wrecker and change it...in the time it took you to write this thread and wait for replies you could have gotten your aircon working...

you must have read over the part where i said i wasn't keen on a crappy 2nd hand replacement. my dash is apart already, i know what's involved in tearing the thing apart and i DO NOT want to be doing it again a year later when the 'wreckers part' fails.

my air con has been playing up for ages. all i get is hot air

the compressor and gas has been chcked and they're fine.

how do i perform an air con diagnosis?

The only thing i can see wrong is the display is out of whack when i turn it on during a hot day. but the functions/fan settings still work when i press any of the buttons.

the easiest way 2 check the a/c system is if u hear the ac compressor in then it has gas in as the compressor wont cut in without pressure in the lines. if it wont vary between hot and cold. stick ur head under the dash and get a friend 2 vary the temp between hot and cold and u should c sum levers move on the side of the heater box. if u cant c anymove then there is a problem in that part. hope that helps

Most likely not the motor itself. Its actually mechanical as described above and its very common. This is the same part that makes that clicking sound on startup on other skylines. Gearteeth are just probably completely broken off rather than just a few.

Have fun pulling out the dash

If it has gas in it will get cold (actually the vaccum makes it cold nehow). To check compressor&compressor clutch operation start car, turn on ac and see if RPM increases

    • Greg speaks wisdom. These dirty old Datsuns are only value when they are cheap. When they are not cheap, there is no value. Sounds contradictory, but it's true. We are now 20 years past the hey day of modifying cheap 90s JDM cars for small amounts of money. This is a different world. If you are rich and can afford not to care about what is effectively wasting money on an old Datto shitter, then I have no reason to argue against it. But if you are wanting to experience what we all experienced back in 2005 (and I bought my car last century!) then there is no way to do it.
    • Short answer: No. Medium answer: No, because you still need to conjure the things out of thin air to bolt them to a NA to make it a NA+T. Long Answer: No - The things you need to conjure - meaning a turbo, intercooling, manifolds, exhaust, intake/manifold/piping, clutch, injectors, fuel pump, AFM (?), ECU + Wiring (woo, N/A loom fun) have to come from somewhere. You could have many scavenged these things from an OEM car that someone had upgraded from and use some of these. This will be cost prohibitive now, especially so in the USA. You'd probably pay the same for newer, upgraded components that are better than old OEM stuff from 25-30 years ago. None of these big ticket items are re-usable for the N/A car. Why not buy new and upgrade while you're there? The only real consideration is turbo and fuel sizing and determining whether you want to stay within the bounds of the OEM engine or get into rebuild territory. These limits ARE lower with a N/A motor and especially N/A gearbox at the starting point. And if you're gonna upgrade those then you may as well consider having them built to begin with. Because everyone here knows you're never far from that next engine rebuild once you start making the power you want... The cars you see on the internet and SAU etc have been built over decades. If you're really clued in... you would sell your US car to somebody for what you paid for it. You would then scour AU JDM pages or SAU and buy a car like Dose's on this forum with your powerful American Dollar. This will save you so much money in the long term. Importing it could be tricky. Or it might not because USA. I have long said the only reason 90's Japanese stuff took off was because a) Japanese people had Japanese cars so that is what they used b) Australians could import these cars to Australia with very minimal changes and use them on the road here c) Neither country had well-priced access to US or EU Sports Cars. I don't believe the JDM scene would have taken off in Australia at all if we had EU priced EU BMW M offerings, or more especially the AUS V8 Scene would never have existed if we had the multitude of US cars like Camaros, Mustangs, Corvettes at the prices you folks do. After all - Do the math. I would say put a V8 in your R34 and that's the smart way forward. It is. I did it. I know this from my own experience. But at that point there's no reason to simply not buy a C5 or C6? It would be simpler and easier and cheaper and bette-
    • Reading all this... hurts lol. I have an ENR34 5MT and I paid an inflated USA price for the car alone, had to do tons of preventative maintenance past that, and so I'm over $30K USD into the car already and haven't even touched power.  I wanted to +t it. Not even trying to make GTR numbers, I'd be happy with 250hp.  Can I get away with paying much less to make that happen?
    • Damn you’ve done well, definitely snapping necks.
    • Great weekend and event. Open fire at the caravan park, perfect weather all day and a great feed and a couple of drinks at at awesome country pub.
