R32 Heating Issue

Hey

Recently been attempting to rectify an issue with the heating in my R32.

It seems to not adjust temperature from hot to cold, or vise versa, it just holds one constant temperature no matter what the unit is set on.

I ran it in that diagnostics mode and didn't mean shit to me, so I gave up.

I did a little test yesterday, I started off by bleeding the heating system and thats all fine, water is flowing fine through there.

I then checked the radiator hoses to see if they where the correct temperatures, that was fine, bottom one cold, top one hot, and hot water is feeding through under the manifold through that heater pipe.

BUT

The heater hoses on he firewall are dead cold. They have water in them it feels like, but it is not warm. I'm assuming thats why my heating is not working, but why isn't the hot water flowing into the heater core is my question?

I tried it when the car was cold, idled till it was at operating temperature, even drove it hard so it was well into operating temperature and still the heater hoses where cold.

Any help would be appreciated.

Thanks,

Abu

Sounds like a problem I was have at the start of the year. There's a motor near the back of your dash which controls the hot/cold, but before you go and check to see whether it's stuffed, try holding down the 'heat' button for like 10-15secs or until the sign 'FH' appears. If you still get no change in temperature, it's your valve.

Let me know.

Hey Adam!

Tried that FH trick last time, unfortunately no change. What does this mean?

Thanks,

It could be your connecting rod which has disconnected off the hot/cold flap.

Common problem on the skylines and an easy fix.

Look at the footwell of the front passenger area.

Look up under the dash (behind the headunit)

There should be a metal threaded rod which moves side to side. This should be attached to a plastic clip.

Where abouts do you live again?

I can drop by and have a look around for ya

Shoot us a PM if you can be stuffed

Hi Patrick

I am from Hallam man, probably about 20 - 30 minutes from you.

Connecting rod hey, I will have to take a look when I get back from work, if I have any issues I will send you a PM.

Do you I have to pull the centre console surround out and the headunit etc? Or can I just see up from the foot well? Cant picture it right now in my head, but will make more sense when I take a look at it when I get home.

I get what you mean though.

Thanks,

Abu

You'll be able to see the motor from the passangers foot well. It should be at the back of where the headunit and that would be. Depending on where Pat lives, I can check it out for you. I'm in the Dandenong area. :laugh:

Oh ok mad. Thanks again Adam.

Haven't even bothered to look yet, just cant be stuffed doing anything after work.

Will go out soon and have a quick look. Will let you know if I need help, you wouldn't be too far from me.

Thanks! :)

Just give me a PM if you need any help.

The 'FH' is 'fast hot' or something like that. It should ignore the sensors and just throw out as much hot air as possible, but you said nothing happens so it's probably your motor. Make sure you did this while your car was warm :D

      Duncan's V37.......race car?

      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.
