Climate Control Air-Con not working.

[hsvpunk]

Gday everyone.
Well as title says... Climate control air con wont work for me.

I after id been at the car wash, thought id bang the air con on to cool me down abit.

Push buttons, didnt work.
I can up the temp n down the temp but no air thru the front, side, or rear vents. (there is air thats pushes onto the window (dash board vents) and cold air WILL blow at my feet.

Turned car off, as i was at a shopping centre getting some booze, tried it again, and still didnt blow cold air on my face.

Any suggestionsas to what this problem could be ???
Cheers Marc

There is a thin vacuum hose at the rear of the intake manifold which often disconnects and causes the loss of vacuum. This is only one cause for the vents not working but I've found it is the main reason. I don't know how many times I've written this but it's a lot.

I need to clear something up first. Can you switch between windscreen and feet and have them both working normally? When you switch it to face does it not come out of ANY vent and sound like a blockage, or does it still work only on screen or feet when set to face?

I know with mine, sometimes the face setting doesn't work at all and does what I described above. Mine has a faulty vacuum solenoid which is located under the stereo behind the console. Sometimes when I bash the side of the console where the stereo is it will kick the vent back to face.

If not then you have a vacuum problem as already mentioned.

Thanks Scooter I`ve asked about that and got no answer.
Did you buy a holden vacuum solenoid or go somewhere else?

Thehose you speak of would be the black sqr looking hosue which slides onto the abc of the climate unit? if so i will look at that today or tmrw.
Thak you for your reply.


Scooter79, yeah i can switch btwn the 2, but even when you turn it just to the normal air con bit (no front demist) nothing would come out the front vents.
Cheers for replys guys.

The hose I mean is thin and round (about as thin as a pencil) and it should be connected at the rear of the intake manifold of the engine. You will need to look between the engine and firewall. Often this hose comes off or is loose which results in loss of vacuum. As I said this might not be the problem but it happens a lot.

sweet cheers, il go look now.

[NORTI]

is that the same for climate? or just aircon?

WTF is 'the normal air con bit'? Basically if everything is working normally except the face vents then you have a faulty vacuum solenoid. Nothing to do with your vacuum lines in the engine bay. If it was a loose or disconnected line then you wouldn't be able to switch to any other vents.

[hsvpunk]

Thw normal air con bit being where air flows freely thru the car.... as in NOT blowing hardcore against front window (eg when its fogged up)

Well started the car again yesterday to go out, and tried the aircon, and it worked fine. So i dont know what was wrong with it, as i hadnt touched anything.
Thanks for your replies.

Honestly, I wonder why I bother answering a question when it just gets ignored

READ MY PREVIOUS POSTS. #3 and #9. YOU WILL FIND YOUR ANSWER THERE!

I wish you would answer my question. I`ll listen.

[Scooter79]

I haven't replaced mine yet and don't have a price. I've just had to live with it for the past 12 months. When it doesn't work I just have to bash the console as mentioned and when that that doesn't work I set it to face/feet vents and hope that I hit a bump in the road that kicks in the vacuum solenoid.

[NORTI]

anyone answer MY question?

I have a similar issue, so Im asking is it the same for climate control, or does that work diferently?

Used to blow cold air thru all vents, now only at the floor, this cannot be changed with any amount of button smashing

[Surfwagon]

I had the same problem with the face vents just shutting off and as explained earlier if you bang the side of the console below the radio they would open up.
You can still hear the fan running but no air or very little cold air is coming into the cabin and mainly around the feet.
It turned out to be the vacuum solenoid which is situated below the radio behind the console.
Replaced it and now the AC works perfect, Holden part#92140248 solenoid vacuum about $100+.
I just went away for those last 30+ days (Sydney) and glad I fixed it.

so surf wagon, the answer was .... ?

Yes, it is the same for A/C & C/C ?? Or No it is not?

No it's not the same. The A/C control like in the executive models is controlled with manual vacuum plugs that are attached to the back of the unit. They are opened and closed as you turn the dial.

The solenoid for the climate control which we are referring to is electronically controlled by the climate control module and is not used in the basic executive style unit.

I hope that makes a little sense?


Edit... I just noticed you have a VR Calais which has the electronic climate control, so now I'm a little confused as to what you are asking.

[NORTI]

I was asking if the above problem & solution is the same for climate control, yes in my VR.

My Calais Climate worked fine when I got it, then within a few weeks started to only blow cold air @ your feet no matter where the setting was for....

Soooooo WTF is wrong with it? Any ideas?

I hope that clarifies things?

Does anybody have a picture of the solenoid box? Or could describe its dimensions?

I'm pretty sure I know what and where it is, but I just want to make sure.

[Surfwagon]

If you pull off the radio facia and look below the radio near the floor you will see a rectangular black box with 5 x 10mm holes in it .
If you do replace it be very careful removing the rubber vacuum hose manifold off the back of the box (it has 10 hoses attached to it), as this manifold is no longer available new.
It seems that the VR/VS has reached an age where a lot of people are having the same problem with this solenoid, I should have taken some pics of the instal.

Sorry Pete

Wish I did take some pics when I installed it.
