passenger side right above the airbox 1 plastic line it loves to pop off
SOURCE: ac vent problem
the vacuum canister is located under the battery tray on this model truck, however the most common problem are the vacuum lines that run around the battery box. usually the battry will leak acid at some point in time and create holes in the small hard plastic lines. i would remove the battery and check the vacuum lines first.
