it is a broken vac line. check vac. distribution block above the brake booster... there should be an A/C line. check if that is broken. if it isn't, follow it and see if it's cracked anywhere. they tend to get brittle. if that's still not it, then under the passenger side dash there is another set of vac lines for the vents, check those.

what year is it? i have a 93 and had the same problem, the line was broken right at the tree there above the bb because that's where it bends
