Yes - it'll be somewhere in the smaller vacuum line that comes off the brake booster and goes through the firewall to the power/vacuum module for the ATC system. Don't know where exactly, but the line should be black in color.
The power/vacuum module is mounted to the front of the air box behind the glove compartment. Its job is to redirect engine vacuum to the various vacuum motors that control the blend doors.
The system has a self test you can activate by pressing bi-level, floor, and defrost at the same time until the display starts flashing.
