Air Con Climate Control Temperature

[Marko R1]

hi guys,

my climate control module in my r32gtr adjusts from 18deg to 32deg however on 18deg it is cold...as soon as i go above this temperature (i.e. 19deg +) it is hot.

i cant seem to get a warm setting - could it be a fuse or maybe there is a control valve under the dash which needs attention?

this is just on a fan setting without the use of air con as my condensor & radiator fan for the a/c has been removed.

thanks,

Hrmm, I think my car's acting like this as well. I'll try and suss it out tomorrow and report back. When it's on 21 degrees, it's really burning up inside the car. It could be that my valve is stuck on the hot setting though, haven't actually checked yet.

I'll let you know what happens.

I have the same problem. will be watching this thread with interest..

Sorry, I can't help with any news today guys. I don't actually drive my car so can't take it out for a spin to warm the engine up. I've got to wait for one of my parents to give it a drive (P plater and turbo = fines and loss of points). I'll check out what's going on when my mum gets home from work in it.

wat happens wen u turn it to 20? or 25? does it get even hotter?

[joeyjoejoejuniorshabadoo]

mine is only cold on 18 but then 19 + gets hotter as then numbers go up...

its ok though cos i'm not a biatch

as soon as i go above 18deg (i.e. 24deg) it feels like it gets warmer but then it gets really hot after 30sec or so...i then try back it off and its still madness hot!

i keep dropping the temp down towards 18deg & it stays really hot - as soon as i get to 18deg it will then stay just as hot - it takes a good 5min for it to come back to cold on 18deg.

how does the temperature adjuster work? if its like my other cars it will have a tap which adjusts how much water comes thru the radiator under the dash, is this is the case i'd think this is playing up, could be dirty or getting stuck...can anyone confirmation the location of this tap if this is the case?

I hopefully have an answer for you.

My R34 has a small grill on the dash below and to the left of the steering wheel.

Behind it is some sort of temperature sensor.

When i changed my LED lights i forgot to plug this back in, and presto my climate control would be freezing cold to hot in .5 of a degree on the digital cluster.

Plugged this sensor back in and all returned to normal.

So no doubt your 32 has a similar unit, and it may have stuffed up/broken/not be plugged in and be causing it to act like my climate control did?

i also have a grill which sits on the centre console - are you referring to the grill which has a black hose that plugs in the grill & its about 1cm in diameter???

i also installed led lights in my dash so yes i will definitely check this out later today...i think by memory next to this grill there is also an electrical plug hmmmm

[Granthem]

Thats the one. There is a black hose and also an electrical plug. Check both of these out and see if you forgot to clip one back up!

[666DAN]

That'll be it, I've also done the same thing before

[Oosh]

Have you tried putting the Climate Control Unit in to its diagnostic mode?

I can't remember the details how, but there's a tutorial on it in the appropriate DIY forum.

[Marko R1]

i will check out the diagnostic as well - great idea

[Marko R1]

hi guys,

here's an update...i ran thru the entire diagnostics section as per the gtr manual (steps 1-6) & everything comes up fine!

i did notice in step 2 that the number to appear if normal should be '20' & mine displayed '25' (keeping in mind that i performed this test at night in my garage)

it also states though if car is positioned in dark area or exceptionally strong sunlight that the 'sunload sensor' error may appear which is number '25' (this is the result i got) so other than that it seems ok...what else could this be if the diagnostics came up 100% good???

[Craved]

was the sensor plugged in behind the little vent? hose and elecs ?

[Shaun]

Mine does the same.

Where is the sunload sensor??

Apparently there is also a sensor in front of the radiator.

yes it was

Shaun.

im not sure myself - there is a pic in the manual but it is poor quality - my guess is that the sunload sensor is the round thing on top of the dash on the left side...

can anyone confirm the location of the sunload sensore?

[Craved]

sun sensor is in the dash on r33 on left side

R33's dont have the sensor in the front bar, 32's do for outside air temp sensor.

[moobaque]

My air con does the same thing (cold when on 18, hot on everything else). It also pumps hot air out the dash vents where it use to only heat from foot wells and cool through dash vents.

Now this could be related or coincidental but mine faulted as soon as I put in my power fc....haven't put the stock ecu back in to prove that this is the case. But im sure if this was an issue everyone with a pfc would have made comment.

Diagnostics also come back with all sensors working correctly. (return air hose is definitely also attached to the dash)

Cheers
