Air Con Probs R33

[klenn]

Hey guys I have found the problem to the inside sensor, for the whole 3 years ive owned the car I always wandered what the mini airflowmeter looking thing in the glovey was and then it hit me haha so ive pluged that in and the problem still isnt fixed but that doesnt come up in the diagnostic anymore so its just the outside air sensor and sunload sensor, I dont think there will be a prob with the sunload sensor, BUT where is the outside air sensor located??? and also when I run a diagnostic and it comes thru to no. 5 showing the temps there are only 2 readings the first at 30 which seems abit werd because its definitly cant be 30 and the second 18, then it goes back to the menu part where it says 5.

So I suppose my next step is to find the outside air sensor right, I have looked but cant find it, also what does it look like??

Please help me coas im dying to take my car out 4 a blat.

Cheers for your help so far guys.

cheers mate had a chronic look there and cant find anything around there, so maybe it is gone?? unless it is somewhere else on a 33, if someone could confirm this that would be great. there are some plugs etc around there but im pretty sure they are for the old spoiler up spoiler down motors that have been taken out, unless the sensor is on the same loom as these plugs?

cheers for your help so far.

bump for an old thread.

i've pulled my dash out and i've found the culprit, it's a little motor which slides to change the fan direction to face and/or feet and/or demister.

the problem is that when the pin adds or removes the feet from the fan setting, it doesn't stop and continues to try and open up the vents.

i've opened it up and none of the cogs/gears are mis-aligned, just seems like it doesn't know when to stop the motor.

doubtful it's something you can buy from nissan. don't like the idea of buying 2nd hand either.

short clip to the stepper motor (~4MB)

any ideas on a fix or new motor?

you will find one of the teeth are either broken or worn that clicking sound is a pain in the arse . i replaced one in my sons car we paid 45 bucks for a second hand one that hasent given any trouble since .

fun job getting the dash out and back in again lol good luck with it . think the correct name for it is the blend door actuator

thanks for the correct name.

i'll have another look at the actuator, but initial glance the teeth look fine.

might check if a series 2 or an R34 one is compatible

I had a clicking noise when i got my engine changed found out it was under the bonnet a clip had came loose and was jamming the little valve that controls hot and cold water on the firewall, thus the climate control was trying to introduce more or less water to control temps but obviously couldnt because valve was jammed

nah, definitely not any 'valves'. i can see the motor clicking along as it tries to change the direction of the vents.

so far all of the people i have spoken to with the issue seem to be series 1 owners.

i want to find out if it's purely an age/usage thing which accounts for the lack of series 2 owners with the issue, or if series 2 R33s have a better/different 'blend door motor'. and quite possibly try to have a look at the R34s if possible

i've pulled it apart and the unit consists of: 1 worm gear and 4 cogs/gears, with one of the gears attached to the arm.

on one of the cogs the teething has worn down to the point that they are barely interlocking with the adjacent cog.

and another has a bent (almost broken) tooth.

i can see an easy solution by rotating the worn cog ~180º so that the worn teeth won't be engaged (tested by manually moving the arm). this however won't work for the other worn cog as it is the one attached to the swing arm.

might be lucky with matching a cog at a hobby shop, but kinda stumped about the worn cog attached to the swing arm.

will post pics when i get a spare minute.
