I believe i am missing a vacuum line on my 87 astro. The defrost works great, but no heat out of the vents or floor. i just do not know which one or where it goes to? I have gotten rid of a lot of stuff, i can get pics. i also have the haynes manual. I'd like to get rid of as much of the a/c stufff as possible w/o affecting the heat/defrost. already have a bypass pulley installed for the a/c. any info woul dbe nice.

i cannot open the topic that chemist created further down the page at work, i'll check that out at home, i get denied for pornography reasons? whats in that post?
