There is a good chance that the heater core is leaking.

[dannyn12]

could be your drainage from the evaporator is blocked and water is building up

I'd go with heater core leaking

So far I haven't found a thread that tells me how to get to the heater core? My Statesman has a leak and its bl***y cold with it disconnected! Instructions and piccies or linky would be helpful, please. Just found it, here Anything special for those with airbags?

Heater core is a huge pain to replace.

I just got a bottle of Bars Leak and put it in, no heater core leak since

i have a vt commodore when you accelerate the aircon changes vents and blows through the demisters. when i back off the revs it returns to blowing cool air out the dash vents . i dont understand this and it is giving me the shits

Mine has a distinct smell of coolant when the heater is on, and it will fog the windscreen for the first minute or so... I was told it is a bypass valve at the core, and it normal on VT's.... It will not loose enough fluid to worry you, so put up with the smell, or pay $500+ to get it fixed......

If your getting steam, I'd say it more like the core though....

Sounds like the mouse from the ECU (Engine Computer Unit) has crawled into the AC ducting and died... a common problem on these earlier models, because the car/mouse is now eleven years older or more (extremely old for a mouse). An ECU diagnostic will tell you if the mouse is not active any more, just get a new one. If you're handy with a soldering iron you can re-wire a PC mouse to do the job. The smell will go away after a while... just like a dead mouse in the ceiling of a house etc.
