R32 Climate Control Question

[NRV155]

Ok, ive looked in other threads but cannot find an answer to my question, which is, is there anyway to disable climate control altogether so it just pumps out constant cold/hot air?

Dont flame me if this has already been answered somewhere plz

yeah i remember reading on sau somewhere, tutorial i think, about using resistors instead of the sensors to make the climate controll pump out at full power. i also know that if you hold onto the up button for a few seconds it will flash FH full heat. and if you hold down for a few seconds it will flash FC full cold.

i think it was FH and FC, cant remember, you'll know when you try it.

[NRV155]

Ill try that and see what happens, thanks. I read about the resistors too a while ago but cannot find it now.

Do what QWK32 has mentioned and if it still pushes the wrong air, it could be something wrong with your motor which controls the hot/cold valve.

yeah i find the climate control useless.

Never use the auto setting on the AC. Just always set it to 18degrees and choose fan speed

One question i had was, what if its 16degrees outside and i want cold air flowing through the vents. Climate control only goes to 18degrees.

and the air isnt as cold as outside in this scenario

Does that mean it will pump some hot air out to make it 18degrees?

yeh, mine constantly either pumps out hot or cold air regardless of what temp teh controller is at. It can be quite annoying, but luckily atm its stuck on cold haha so its not so bad. Can Anyone help? Sorry to hijack thread...

haha that happens to me.

I pray for it to get stuck on cold when its a hot day

The problem is most likely your blend door servo motor. This controls the hot/cold flap. If the motor is dieing/jammed it will not move the flap according to the temperature you set it to.

To see if yours is working.

Get into passenger seat, stick your head in the foot area and try and look behind the headunit. You will see a metal rod and a white plastic clip attached to it.

Guide your arm towards the hot/cold buttons on the controller, and press quickly up/down. You will then see the white plastic clip attempt to move the metal rod which moves the position of the flap.

If nothing is moving, then its either jammed or dead.

Take it to an aircon mechanic he should be able to diagnose it.

Quote is about $70 second hand motor + $100~ labour to install.

to disable climate control on the R32 is easy.

you hold down the hot or cold button until it maxes out (ie.. 18 or 32) then it'll hit FC (forced cold or f**kin cold, whichever you prefer) or FH (forced heat or f**kin hot). Then you can use the fan button to vary the speed of the fan as it auto defaults to full fan speed too.

if you just want the fan to go on and not engage the climate control, then switch it off (nothing on the screen) then press the fan button. It'll turn just the fan on and blow whatever's outside thru or cycle whatever's inside.

you'll also notice that if you don't turn anything on, a steady stream of air trickles through. if you want to turn it off, then while its off, just press the recirculate button, and there'll be no air movement at all thru the system.

hope that helps... if your climate control isn't workin properly then its most likely that flap... sometimes its easy to fix yourself if its just jammed... I might post a DIY on how to lubricate/clean the lever assembly. I gotta clean my aircon filter this weekend.

oo didnt think about adjusting fan speed in FC mode, will give that a shot!

Wouldnt this blow at the displayed LCD temperature? I press the fan button and then the up arrow and it makes it hot air come out. So wouldnt this displayed temp have an affect on the air coming out?

you'll also notice that if you don't turn anything on, a steady stream of air trickles through. if you want to turn it off, then while its off, just press the recirculate button, and there'll be no air movement at all thru the system.

that really shits me especially when flap is stuck in hot. Get this annoying flood of hot air.

Ive tried pressing the recirc button but i dont think it made a difference? Will give it another try

DIY would be great, not really keen on replacing the motor cause its too much money hehe

just the fan button (press repeatedly to control the speed)... if you press anything else it goes back to climate control mode and pwn's your ass.

ah awesomeo cheers for the tip

[NRV155]

Alot of useful info, thanks. My problem is that even if i got it on 18 degrees, it will blow cold air for a bit then blow ambient air for a while, and then cold again. Its not just constant cold air. When i press 'amb' button it says something like 37 degrees. Next time i drive my car, i will try the things mentioned. Thanks again.

I think that could be your system controlling the temperature. Like it reaches 18 degrees when it's blowing the cold air, but when it reaches the 18 degrees, it'll blow ambient air to keep it at 18 degrees not make it go down to 16 degrees or what ever.

Just hold down the 'cold' button for about 10secs or until 'FC' comes on and it should continue blowing cold air like others have mentioned.

i have an r33 but im pretty sure they have the same air con system.

first of all the temperature of the air depends on what mode you have it on or whether or not you have pushed the a/c button.

if its just the fan going it will push out ambient air, if the a/c button is pushed you can control the temp by the red/blue buttons and the speed by the fan button.

the Auto setting is a tricky one to figure out. Due to alot of the sensors in the older cars being screwed and the valves have all either broken or gotten stuck the auto button is usually not worth using imo.

the re-circulate button is the best as you dont get all that annoying hot air coming out at your feet and you will also notice a slight increase in the cars performance and fuel economy.

so basically just use the fan button the turn the air con on then select which ever mode you want. Then use the temp buttons, just avoid the auto button as its just a hassle.

r33 and r32 climate control are very different. r33's don't give you as much manual override as the R32.

In my R32 the climate control works fine, then once i had it set to hot, no matter what i changed on the control screen stayed hot, then few hours later it was working again. Im thinking either the motor that controls the flow to the heater core was sticking or the cabin temp sensor may be faulty, any ideas?

[adam-__-]

I think it's the cables to your motor. Mine was stuck on cool air and with the shake of the cables behind the dash, it got everything back to normal. All the motors worked properly again.

Ok, i tried the full cold thing (good to know) but didnt work. Is there anyone in sydney that specialises in nissan air cons?
