Not huge issues cause i still have hot air though. But it rained and made me realize i need a defrost function still. Those little vacuum lines dont seem to be pinched that come off the back. Maybe when i re assemble it they become pinched? Anyone have any luck with these issues?

the other is a vacuum issue. start by tracing the lines in the engine bay (as crazyman suggested). it's not uncommon for that line to slip off the intake manifold.
There's a little metal guard over the lines to prevent pinching...so that probably isn't your problem. if you know you're getting vacuum to the switch, it could be the switch itself. it's a fairly simple mechanism, with little sliding plastic pieces, if these don't seal (there's some sort of grease on there that helps...but it seems that it usually dries up), you'll have problems. I tried a few different switches, with no luck.....so I did this:
that was 3 years ago. still running it like that. always just on Heat and Defrost. which works fine. I think I'll try the switch from my parts car in it before I sell it though.
