HVAC Vacuum Leak

HVAC Vacuum Leak
I clearly have a vacuum leak inside the truck. The "hissing" air noise sounds like it is coming from the hvac control unit. I have tried taking out the two screws and pulling the hvac unit out, but it doesnt seem to come out very much, if any. Does anyone have good instructions on how to fix this? Will I need a new hvac unit or just a vacuum line? Visual instructions would be great. Thanks in advance.
