there is a vacumm line under the hood on the right side that is most likely disconnected on the drivers side , take the battery out. it has probably leaked acid. look at where it has been leaking acid. find the broken black hard plastic vacume line - slide some rubber tubing over where the break is.

The trunk release for a 1997 Chevy Lumina is located on the driver side floor. An emergency release is also located inside the trunk.

Check the floor heat vent and defrost to see if air comes from them. The vents will be vacuum controlled and a vacuum leak will make the vent doors divert air to the wrong place. Check the entire engine and climate control systems for a vacuum leak.
