1994 chey van Sign In

Hi, I'm new to the forum and it looks very useful. I have a 1994 chey 1 ton van, 12 passenger. When i turn on the heat, a/c, or defrost, I can hear it blowing somewhere but not into the cab of the van. It seems to be blowing into the engine compartment or somewhere else. Is the a door or somethin that i can easily check and see if its open to let the air in? Thanks for any help

Pretty sure this vintage used vacuum to actuate the doors. Usually when a vacuum line break or it's storage ball it will default to defrost vents.

I'd look for that first. Many vacuum lines are plastic and look like wire - easy to break. Easy patch with like wiper/washer hose if you find one totally snapped or you can cut a bad spot out and use hose,
