Finding a vacuum leak that could cause your problem could be almost impossible without a smoke machine.
But they are too expensive for most people to buy.
You might call around to some shops in your area to see if they have one and take it to them.
I would like to rule out some other things, but I need to ask some question.
What is happening to make you think it is a vacuum leak?
Does the air blow out the dash vents all the time, even when it warms up?
Does the AC air get cold before the engine is hot?
How much driving does it take before the air heats up?
