After having a new deck installed, my a/c in on constant cold. While this is fine for now, ill eventually need heat :P

With the temp either on 18c or 32c, the air is pretty cool. "FH" and "FC" doesnt make a difference, nor does the car running for an 5 minutes or an hour....

As I said, its only come about after having a new deck put in. Are there any sensors round that area that could have come out? Any ideas welcome ;)

not sure with the 32s but on the 33s there is a sensor in the dash front left of the steering column.

it looks like a little breather vent and has a hose connected on the other side from memory.

If this hose is disconnected (at either end) and is close by to something that generates a little heat, i guess it could make the AC work for colder temps.

check it out... wont hurt

Check the sensor near the deck, to the right of it. You may have to pull the deck out (not sure what type you put in there, single or double DIN) two wires and a hose to the sensor. This is the interior temp sensor, mine wasnt connected (actually, wires were cut, damn thieves :( ) and only hot would work. Try look, you never know ;)

for now yes...but what about when its cold?

Anyway,

I ripped out the climate control sensor (next to ure left leg) and all works correctly now, bar the climate control. I cleaned the sensor with wd40, hooked it up, no go. So looks like i need a new sensor :(

Any1 have an idea on $?

something would have been disturbed around the control area.

the venturi near the clutch pedal draws air from the sencor in the dash to test you can blow through the pipe slowly.also put a rag over the light sencor.

other problems ive had with my passage [same as later mosels]is the hot water sencor reading cold[on the wrong pipe] so the blend door/heater tap motor shuts off to wait for the engine to heat up.a crook thermostate will do this to.to check the door motor will move a little on start up to let a little water through.then close.

my passage R31 climate control freezes up regular to stop this R32 on have a sensor before the evaporator to compare before and after.if these are faulty or dirty it wil go into defrost and go full heat no A/C.

      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.
