Air Con Probs R33

[klenn]

hi guys thort id try and pick your brains and see if anyone knows much about air con in these skylines.

when I change from the different settings from demister to feet it makes a click click clack noise from somewhere it sounds somewhere at the top of the dash, I have done a search and apparently it is the plastic cogs on the stepper motors, whats involved in getting these stepper motors out??

Also when switching the climate control it is only cold at 18 and the rest are all warm which is annoying, I have done a diagnostics on it and its coming up with

outside air sensor

inside air sensor

sunload sensor (not sure if this would be faulty because I did the test when it was in my garage.)

How can I find the other 2 sensors? and how can I test them?

Any help would be much appreciated, im sure with all the r33's around theres gota be someone whos had these probs aswell.

It seems that I have the same problem as you. (you can only turn the stereo up to cover it for so long lol)

Im really keen to find out what is involved in getting to the controls.

Somone here had an english workshop manual maybe there might be some help in there??

should be the same for r33 in my car the sensor in a little vent to the left of the steering wheel was disconnected which caused problem u described, could be any of the sensors thou....cold air at 18....anything more it went hot. also when u did the diagnostic did it tell u the temp the sensors were reading were they all similar? because my the faulty sensor in mine was given a really different reading......as for the noise i get that too is abit annoying!

i'm having the same problem. where is the sunload sensor located? i've only found the inside sensor as descripted by rod. i've no idea if it's working not. how can you check the readings from them and if the sensors are working? thanks.

i also have the same problem, but mine only happens when i put the temp over 24-25, pretty weird sounding

i've tried kicking it a couple of times and it hasn't helped

ive got it as well.. just the vents clicking for like 20 seconds when they are turned on... then its ok.. ill check these sensors.. thanx

I've found I can stop the clicking if I leave the air on face and feet all the time... then it doesn't click when I start the car. It will still click when I turn on the climate control or change the direction of the air, but by then the stereo is on. Bloody annoying but from what I understand its a whole days work removing the entire dash to fix it then put the dash back together. maybe I'll fix it one day... maybe

The sound you guys/girls (if any) is the sound of the gears slipping on each other when you're trying to change the direction. The gears have probably just worn out over time. To change it, I think you have to take out the whole dash to get to the heater core.

I dont mind doing that as long as I know what Im doing once I get it off and can get the parts to replace them.

Not looking forward to pulling off dash and then having to put it back together if I cannot find out what the problem is or source parts.

I'm not positive that your problem is the gears, but I heard it was common problem on the 33's heating system. I'm just giving you ideas mate. I don't want you to rip out the dash and found nothing wrong inside. Taking the dash out seems like a huge job.

that sounds like my issue. the gears, mine only does it for 5 seconds when it turns on or off.. dash is easy. just need to find the gear thats clicking//:action-smiley-069:

does anyone find that below 24-25 deg it stops clicking?

Hey mate thanks for that, have the cover off and the only thing that leads to that vent is a pipe.... so does this mean the sensor is missing or is it in a different place?

[rgr34]

hey mate in my r34 there is the plastic pipe u describe and another plug for sensor connected in........ someone with a r33 needs to confirm its the same.......i would imagine it is thou....the plastic pipe connects to the back of the unit and the from memory the plug is on the side u see anything like that?

[5hu7o]

i have the same problem but its only when i start the car i turn the key and it goes for about 20 seconds but after that its fine

[DK1983]

same issue as above, but only for around 6 clicks, but then if you listen closely espcially in the mornings i can hear like "water running down the sink" sound coming from the engine bay???? could be related to the air con issue im not sure. wondering if anyone has heard a simular thing??

[nizmokid]

guys it it the motor on which switches the vent over, mine does the same thing but I have got a second hand motor and just have to find the time to be stuffed to pull the whole Dash , cluster ...pretty much everything aroundthe dash to get to the motor.

5-6 hour job I believe....I will get around to it some day......car is only driven on the weekends anyway!

Hey thanks man yeah it would be good if someone can confirm if there is a sensor there because that must be the climate control problem if it is missing, seems abit werd tho because there are no wires there or anything.

cheers.

Some say that it'll take about 6 hours, some say that if you know what you're doing, it'll only take 1 hour. I think it's best to get someone who's taken out the dash before to help save some time.

[siddr20]

Yes it does take 4-5 hours..

Its a big job taking the WHOLE dash out..

thats right, you gotta take everything off..

This guy had pics up here on how to take the dash out: http://gtr.ferni.net/misc/dash_removal/

BUt seems like the link isnt work anymore

"ferni"-- hmm that name sounds familar.. im pretty sure hes on this website..

hope he sees this
