My vent control is stuck on defrost which I know to be a vaccuum leak (as I know the mechanicals are all conected). Where in the engine compartment do I look for the leak?

Usually the source line goes through the firewall near the heater and a/c lines. Will be a small black plastic line, usually has a check valve on it somewhere and might even go to a vacuum resevoir (small plastic bottle)

Thank you! I found the disconected hose and it all works now!
