1998 VT Berlina aircondtioning

[ferrous oxide]

my Berlina a/c loses vacuum to the vent flaps when the engine is under power especially when towing my boat. any clues as to why and is there a fix?

[Doctor Bob]

try the check valve just near where the hose connects to the inlet manifold

Thanks but unfortunately this did not fix the problem, any other suggestions of where to look?

[Tasmaniak]

perhaps in the air condition section of the forum? You might get better luck there

Being a Berlina i assume it has climate control. All the directions for where the air blows out are vacuum controlled. When there is a vacuum leak in the system the default is that the air will blow out the windscreen demist.
Now to diagnosed the fault you will need to put a vacuum pump at control pack and check each individual circuit.
If you need any more info pm

Oh no!
I have a 1998 VT Berlina as well. I was wondering why when travelling at 110kph the air wasnt coming out of the vents only the window thingy. Also my air-cond doesnt even work, and it's always over 35oC during the summer where I live!

How much would it cost to have fixed? I have to get a new compressor as well.

Same problem here... air-con works occassionally sometime not... noticed that air went to the window demist at random times... usually when driving over 100

is there an easy fix?

[Rhin0o8]

ive just fixed mine in the last few days.

PM me for details
I'll try to post up pics aswell

Well, got a quote from a mechanic in the town i live. He said it will cost $1000 for the new compressor to be fitted!!! OMG!

[Head_is]

Wow $1000? The new compressor in my old VY was only about $300 odd, Fitting it shouldn't cost that much extra it wouldn't take that long

[HSVBoI]

The machanic said it would take a day? Where'd you get yours done?

[Head_is]

I never did get it done and it fixed itself, it had some sorta error in electrics that stopped it... weird.. Oh I just see compressor after all that. Mine was only the blower fan motor... sorry. But all the old commodores blew air whenever under load out onto the windscreen

[HSVBoI]

SO what was wrong with yours? Mine blows air out the windscreen on cruise at 110kph and my compressor is noisy or something, so the machanic dis connected it and yeah. $1000 for a new one. Was told it would be cheaper at other places. I also need to replace the globe in my climate control so i can see the screen at night.:|
