VR Climate Control, feet only??

[NORTI]

Hi Guys,

Ive had an issue for awhile where my climate control now only cools your feet?

A VERY small amount of air comes out of the correct ducts, but most of it hits your feet, no matter which mode its on.

Swapped over the solenoid box thinking that was it, but no, exact same issue.

Anyone got any light to shed on this?

The hoses still seem intact, & with the centre console out, I can see that its blowing from the ducts below those that route to the rear thru the centre console.


Please help?

are all the vac hoses connected to the valves?

Can you move the side valve (drivers side up under the dash) by hand - ie open and clise the vents.

Also I have printouts at home of all the VQ climate setup from the big book. I can bring them into work if that will help you.

Mate I have the exact same drama. and was just going to start a thread on this. Hope that there is some that can help us

do you mean at the solenoid end? the little rubber vaccum manifold??

Looks like all the hoses from the dash are into the back of the manifold, & then I made sure all the white plugs were snug into the manifold.

Im going to go look for this side valve now!

BBS!

The vacuum opens the valves to let the small gates open and close - directing air flow. Can you move them by hand - ie not jammed up some how.

Here is a photo of the things you need to make move

cant find it at all, nothing like that is there?

[88GreenVN]

You will have 4 of them.

[NORTI]

four of what?

I dont have the black thing on the drivers side at all?

[88GreenVN]

OK the vac lines go to something..... what ever they plug into will drive the vents inside the heater box.

[NORTI]

well I know where the red one goes, & where the beige one goes, Il lhave to get the torch uder there again & trace the rest

[88GreenVN]

If you unplug red one do you hear the air suck in?

[NORTI]

cant reach it. it that part only on climate models? or on aircon models too?

[88GreenVN]

All heater boxes have the small round vac units on the heater box - just the CC units are controled electronicly and have the vac pack under the heater box. The standard system had the vac lines hooked up to the twist control knob.

cool, so I can go raid one off anything.

Im not looking forward to the fact that it appears I may have remove the whole crash pad to get at this piece of crap.

No - should only need to remove the front panel (radio bit) to get to them. Also the black plastic bit under the glove box.

Already have taken off all the radio surrounds etc,

its way way underneath, Im going to have to take out all of the aircon ducts to see if that gives me more room

yes that will help

after reading this thread last weekend i went and ordered the solenoid block and fitted it in this morning. absloute friggin pain in the arse spot to get at but after about 2hrs stuffing around, took it for a drive and FINALLY the climate control works perfectly! haha woot

[NORTI]

lol I think that might be a different thread.....

Im glad yours worked out okay, wish mine was fixed by that

[crawfy]

lol oh yeah, seeing as you only started this thread today... one im thinking had the part number for it posted

yeah really happy that it did fix it, and that i hadn't wasted 90 bucks on something that wasn't broke

Check the T piece going onto the manifold again and make sure the one way valve is facing the right way and works. Should be only able to blow through it one way.

thx wavez, Ive narrowed it down to a vaccum issue somewhere involving the black hose....

Ill check the T-piece again...

Check the line into the vac ball under the front left gaurd too.

[NORTI]

Okay, so here is the saga....

after 3 solenoid boxes (yes 3, I went & got ANOTHER one), 2 climate control dash units, 2 spare vaccum diaphrams, & a very handy piece of hose.....

its fixed!!!

So, we narrowed it down that the dash thingo, is fine.
The solenoid box is working correctly, & using the hose we cycled thru & sucked/blew thru all the valves to check. - Allgood.

So then maybe not getting vaccum in? Checked recently replaced vaccum ball connections, allgood.

CHecked T-Piece has 3 hoses... whoa, one not connected, ah-ha you say? Noooooo, connected said hose, still an issue

Recheck all actuators with the hose.... all of them work....

Back to engine bay, use hose to check vaccum going thru firewall, allgood.

Still why not working?? hmmm, follow all vaccum lines around engine bay, remove engine covers, crawl over manifold....

then sit & think.... did aircon play up before or after new spark leads??? After!!

By feel, find that there is a small nipple for one of the hoses on the t-piece to attach too, guess what? when doing the lead change, have knocked little itty bitty hose off....

for refrence, this hose is located to the right of the dizzy, underneath a larger hose that runs under the dizzy, cant see it, definetly cant take a photo lol


so great drama is finally over, & much dust entered my car after 6mths of no face vents working lols....

(as a side note, I realise that I totally bluffed my way thru regency about the demister.... ha!)
