Yes, there's two small plastic lines going into the AC box by the blower resistor. One should be black, coming from the vacuum reservoir. The other is grey and goes to the hot water valve. Check those and make sure their not damaged as well as the the one between the vacuum reservoir and intake. Theres also a vacuum gang plug on the AC box behind the glove box.
