What powers the aircon compressor?

[Johndom]

I've just bought a 2006 Caravelle? I think.. 1.9 LWB
The aircon compressor is not working, we have worked that much out. We are trying to work out if the compressor is powered from the computer or from another control module.
Does anyone have any experience with aircon electrics?
thanks

I believe it's a dedicated module (near the battery?). The Denso units in Oz T4s were a local fitment rather than a factory fit.

I have the same problem on my 2006 Multi
The compressor is turning but not cooling.
I cant remember if an icon is suppoed to appear on the dash control readout to say if it is aircon mode,

Normally the air con button lights up when the air is on , there are no indicators on the dash . You should check all fuses and also relays to ensure its being powered also remember the air wont work unless the dash fan is on .For fuse and relay locations check here T5 FAQ and How to THREAD (up to August 2009). There are two fuses for the Aircon so it pays to check BOTH .

On mine there is no button to switch the aircon on you just put the temp to low and it used to come on?
The fan works and I have checked the fuses I can find.
Also the dampner on the compressor is turning?

juat checked mine and the fans work and I can hear the fan behind the rear seat on the drivers side working but no cold air?
I have checked all the fuses on the card and there isnt a fuse near the battery even though others have said there should be, it was working?
Will try and take it somewhere to have a look tomorrow.

Thanks people, I'll look into that, I'm still waiting for a working compressor to arrive. The first one didn't work.

Apparently the commpressor is knackered
Does anyone know the part number or know if I can get aftermarket as Vw want $1400

Try JM Auto Air 02 9718 2209. I told him what car and he knew which compressor.

Recently for my MK4 $350 compressor $40 receiver drier and $25 shipping to Brisbane

You will need someone to take down and regas. Gas is on a credit basis and any extra you need is $150/kg, I needed 300g more than I had.
