Thanks Rekin for the pics, you're a champ m8 ;-)

Mine had the exact problem as you've described. The servo arm dosen't move when I cycle through cold and hot. But when I wiggle the plug while doing that, the servo arm moved. So I tried taping up the wires, pushing the wires upwards, and all sort of other things.... but still have the same issue.

Eventually I was able to find a fix, the trick is to apply a slight pressure on the actual plug towards the right (back of the car). There is a rectangular void on the left of the plug and all I did was stuff some paper in there to create that pressure and the problem solved. I was able to get cold air again!! Bloody awesome. Thanks Rekin!

thanks to the both of ya! mine had the same problem but was stuck on cold even though ac doesn't seem to work but as it was stuck in the cold position so i didnt have heaters, so i too so stuck some paper in that gap and now they work perfect gunna save me on those early morniong starts in winter thanks again! guys

Hey guys,

I too am going through R32 air con problems. My servo motor is moving, I had my air con re gassed and serviced but no luck. I found a way to run the air con in diagnostic mod and the A/C does get cold in that mode... Just not in normal mode.

According to the following my outside sensor is causing the problems.

So if you need to test you sensors here is the instructions for Diagnostic mode.

hope this helps.

just ran the diagnostic and came up with 25 so what is this senors purpose ? and what will happen or not happen if its not working? thx

Big shout out to all who have contributed to this thread, thank you all, it has saved me a lot of time, sweat and my kids ears from swear words!!! Also found my mode motor had the same connection issues as the blend motor.

woah thread back from the dead

so anyway recently i turned my aircon on and it won't blow cold air it just blows ambient air at me, the compressor doesn't engage

every so often i can turn it on and it will work, but mostly not

from reading through some of these posts, it's either some kind of electrical fault or it needs regassing?

I'm far from an expert on all things air con but i'll have a go! If the clutch in your compressor only works every now and then it could be more an issue with the compressor (either electrical or mechanical fault) Have also read before that low gas levels can make the air con play up

Bumping too, it's summer, I 've prolonged not fixing the A/C as long as possible, but its FARKING Hot.

I'll give the paper in the socket a go, I juts want cold air, winter = drive with windows down

Btw, does anyone have problems with the "recycle air" button? Mine doesnt seem to want to stay on

is the demistor supposed to be able to be on without the air con?

because mine will only come on with the ac and the servo motor or whatever moves but it i select it to 32 degrees it doesent move as much as it does when im not in demistor mode and the air coming out wont be cold but it wont be hot and i need it to be hot to get over the pits.

any help appreciated cheers

quick way to check that:

puul the AC relay out and jumper it. there will be one terminal with +12v and another heavy wire that feeds to the clutch. if you connect the two the clutch should click.

last copule of these I have looked at were leaking on the front pipes. low gas = low pressure = no go as the pressure switch shuts the compressor off to save it destroying things.

btw - wave at a white signed combo van when it passes you on lutwyche rd of the morning about 730ish. (thats me!)

sorry to ask again but i was chasing some advice on this matter still

should be able to turn off a/c after selecting demist. but demist is hopeless with a/c running. but at 32 with a/c should still be hot

thanks i'll give that a go

yeah matey i've seen you around a few times recently in the morning, i nearly completely ploughed into the rear end of you a couple of weeks ago

you did the alarm on my car a couple of years ago when i was on hamilton road

ok if that is the case:

look at all the joins along the way to the condensor (outside coil) if any of them are dirty then your leak is there. most I haev looked at the leak is in the front right area (standing in front of car.)

it could just need regassing as i have no idea when it was last regassed and i've had the car for 3 years now and i haven't had it regassed and i know the owner before me was a complete noob that wouldn't have had it done

im pretty sure my ac just blows air(neither hot or cold, but as engine heats up it goes warm to hot understandibly as i noticed an ac pipe runs less than 10cm away from the belly of my turbo)

i came up with 23, 24, 25 on diag test.. i knew about th water temp as my gauge says nothing all the time.. but what are the other 2? is it just simpls enuf as replacing them and my aircon works? :S also i havent done any of the other checks as yet

thanks in advance!

Very useful writeup.

In addition to holding the socket in place with some paper, I found that some cabling had been zip tied in such a way that it was inhibiting the movement of the rod connected to the servo arm.

blast from the past.

Ended-up pulling out the blend-door servo motor and resoldering the tracks. Problem solved :D

    • 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.
