I was taking out my PCM to get it programmed, and I noticed a line that was broken off at the fitting. I possibly could have broken it when I was taking out the pcm since the line was in the way, not sure though. Anyway, here are 2 pictures of what is broken, can someone tell me what this is, and to fix it what do I need to buy exactly, or can i just epoxy it back together??
Thanks for any help.

that looks like the vacuum for the heater & a/c door flap, to verify that turn on the heat then turn it off with the car running and see if you hear the door close and a hissing sound..

That looks like a check valve. I'd remove it, go to the dealer and get a new one, can't be more then a few bucks. Then pull the broken part out of the 90* vaccum fitting and plug it back in.

its is a vacuum check valve - mine was broken also - controls where the heat/vent/ac will blow (feel, defrost, main vents) cost like $3 at autozone...

Yep. One line goes into the car for the HVAC controls, one goes to the intake manifold, and the other goes to the vacuum reserve canister on the passenger frame rail.
