Hi I have this whining noise sound like its coming from the dash any ideas?
Difficult to analyse without seeing it however does it sound like wind rushing through a partly closed vent ? perhaps your activating solenoid that controls air intake vents may be faulty ! Good luck.
I tried uploading a sound recording with the post but it failed. and no its more like a vacuum cleaner but a lot higher or a mosquito but louder
Does it happen at start up and then go away?
Is the car idling ok?
Do the vents change ok?
Is this happening with or without the air con on?
Noting to do with start up.
She idles good for a car that has done 261000 there is a slight flicker of the RPM meter but noting to worry about and a slight shake but noting to complain about.
interesting that you mention the AC and vents, I hardly use the AC so I did not notice but the vents wont change off the dash window setting till now.
with the AC on or off tried that last time it come on to see if it could help.
is there a way to upload audio?
Sounds like the air con vacuum system manifold or lines are leaking or vac too low to operate actuators. If you are fortunate could be just lack of vac from engine due to blocked line or NR valve in vac line from intake. My VZ defaulted to air on dash only when vac from engine dropped e.g. when car travelling in load uphill. This meant taking dashboard out to access the manifold, so never fixed it. Sold car in meantime.
The AC vents change now so Im not sure whats going on now
good to know that tho could be something to go off.
Check when accelerating uphill as an example - do the vents change air direction to dash only? That will show if there is a vacuum leak in a/c switching system (hoese or manifold). Used to give me the sh!ts.
its working now can switch vents and it did not change when going up the hills at 45 degrees so I don't know what is going on there. I checked no manifold leak.
what do you mean when you said (This meant taking dashboard out to access the manifold, so never fixed it.)
the manifold is under the rocket cover in the engine bay? it should have only taken 10 to get to.
Yep correct the engine intake manifold is under the bonnet. I meant the vacuum reservoir manifold inside the dashboard. Best left well alone if you can find the whining elsewhere.
thanks that helps fill in the gaps I have to take the dash off at some point any way for another fix.
I once had a phone mount the type that slides into the vent, one off the rubber clips fell down the vent could that be causing any problems?
Hi guys, quick question, my t56 on my vz ss thunder won’t go in to reverse unless slightly rolling back, also sometimes it whines wen changing into 5th or 6th, usually I just pop it back to neutral and put it back in and is sweet again, anyone no what it could be & would it be a simple fix or is a new box in order.

Not to be obvious but don't you think you should have started your own thread or possibly posted in a thread with a relevant topic?
Well not to be obvious but as a new member!! Still working out the forum & the heading is whinnying noise so thought I’d ask, as a staff member you think you would be helping rather than criticising. No problem though will just stop using the forum altogether. Thanks for your help, excellent staffing skills immortality
You've managed 15 other posts so.......
Yeah well I work 7-days a week so forgive me if I don’t read every message, for me this forum is for knowledge & convenience as I have been away for last 10yrs until early this year so I saw heading whinnying noises & thought good place to ask the fellas, as much as I love my vz v8 I don’t have the knowledge most u guys have so I ask, no harm in asking that’s how u learn, I woke up this morning bout to leave for work and I saw your post, obviously I’m out of my element, but I thought that was one of the reasons for a forum, to learn & discuss.
....meanwhile... *Bat symbol spins* *dramatic sound bite* Back on topic...
This outlines how one part of the vacuum relating to HVAC can be faulty.
It's a fairly easy fix
