I have heat and I have cool air. I can hear my fan run in all speeds. It does not come out the vent only when the car is moving.Where would the canister be or the main vacuum source to start the trace for a vacuum leak and is the a schematic/drawing for this. My repair manuel has nothing

you have a vacuum leak under the hood you will find the vacuum line running to the canister or directly into the wire harness. you have to find where its broken. its tricky because there is not alot of room.
