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

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
