Climate Control Air Con Not Changing Vents

[r32matt]

Hey,

The other day when i was pressing the MODE button on the Air Con it stopped changing from vent to vent and is now stuck on the Windsheild Vent. I want to get the front Vents working again. Does anyone know how to fix this? Is there a vacuum line which could of come loose? or is it electrical?

Thanks

i think the venst are electrical, as they can be operated without the car running.

Not sure how to fix it though.

[r32matt]

Anyone else have any ideas please?

ive had the same issue with my gtr for ages. while its off the road im gonna see if i can find out what it is. apparently there is a control box (electrical) somewhere that controls the vents. this sometimes fails. thats all i know so far.

has anybody had this issue or knows what the problem is? im driving an r32gtr

Take all the surround bollocks off from around the back of the A/C, when you press the button to change vents you will see the servo move which controls it. See if the pin holding it to the vent arm is broken or has popped out, happens a fair bit on 32's especially for the vent that controls the hot air from the heater box.

this sounds like a great idea. ill try that if what i have in mind doesnt work.

i finally got the vent check (step 3) to work as it was only coming up with '3' instead of a '30' number. like '31 32 33 34 35 36"

when i ran it, all of these numbers came up flashing and changed from number to number, then stopped back on '3'

from what i can understand, this could either be that every actuator is faulty, or the 'mode door actuator' is.

pretty strong feeling that ALL of my actuators wouldnt fail in one go so i reckon its the mode door actuator.

let me see if i can find this mode door actuator...

anybody know its whereabouts or have a photo of it?

[arep3]

i think this is the mode door actuator. can anybody confirm this before i start pulling things apart tomorrow after work?

much appreciated

[arep3]

r32matt, do you have a copy of the workshop manual? its got a diagnostics part in the heater section. the best way to figure out your problem is to run that fully. pm me if you dont have it.

sorry for hijacking your thread...

[arep3]

does anybody know the part number for the mode door actuator?

[arep3]

anybody?

I was about to post up with the same problem. I havnt got the climate control in mine, mines just the old crap slide switch thing.. I cant close of my external vents or change where my vents flow the air either, when i push the buttons i cant hear the little motor sound any more so ill be pulling mine out tonight to see if what 666dan said is correct or not,, i hope so.. its means i cant really use my aircon because i cant close of my fresh air vents therefore it dont realy get cold... its poo...

cheers

Hey all i have code #21 and #25 come up when i do a diagnostics test can anyone tell me what these sensors are and how to fix or replace them.

cheers Ryan

[arep3]

21 is the outside air sensor. 25 is the sunload sensor.

the sunload sensor will always give you an error code unless its in full sunlight.

the pic that i posted in this thread IS the mode door actuator. it controls the vents (head, feet, half way and demist/window)

it is not repairable....

a new one from nissan is gonna be around the $200 mark and they want full payment before they will order it from japan. so its still gonna be a 10 day wait before it shows after you've paid for it.

i did find one at a wrecker though and they want $80 for it.

if my car was working and i didnt need to save for my rebuild, i would have replaced it by now. and then i could tell you if it worked or not....

[mad032]

do you know where the outside sensor is located and how can i test them.

i have the same problem as described above my ambient temp is always showin -30.... this means?

Ryan

[mad032]

ok now i have fault #22 aswell..... anyone know what this is or how can i access the codes list?

[arep3]

Hope these help

[mad032]

Cheers mate.

Any chance you or someone else knows where the outside air temp sensor is??

i got the same problem on my r33 ..my electrician has gone through the car and the last thing he hasnt had a chance to touch is the climate control.
