Here goes...

Where is the vacuum connection that the climate control system uses to change the way the air blows? I know it's on the passenger side of the engine, but I don't know exactly where. I just know that I unplugged it accidentally yesterday and now my air only comes out of the floor vents.

Reach down just to the right of the PCM, and you should see three different vacuum hoses that connect into the vacuum check valve.

 

I know it's gotta be the one on the fender, I heard it go psssss the other day when I bumped it. Just couldn't remember exactly where it was. Thanks fellas.

 

Glad I could help.
