for only about 10 minutes. it was so nice! the first time they've ever blown coldish air ever. my economy gauge also went to super economical :D. im guessing by this that i have a vacuum leak somewhere and that for just 10 minutes it didnt leak for some reason. any ideas where to look?

Are you a smoker, by chance? You could remove a vacuum line in the engine area and blow smoke into it to see where it comes out at. There are professional "smoke" kits that mechanics use to quickly find a leak, but they are costly. Just an idea. friends of mine have done this with some success. :)
