A few years ago I swapped engines and it seemed like a good idea at the time to remove all the smog stuff and ac stuff. Since then when I turn my heater fan on only the defrost blows and air. It gets warm so im guessing my heater core is ok but I noticed that the air blows into the engine compartment near ac lines. Whats disconnected that I need to reconnect? I dont want to take the dash out if I dont have to but its getting colder here in Wisconsin so I need to fix it fast! If anyone can tell me all the stuff under the hood that needs to be there I sure would be appreciative! As of right now I only have the vacuum line going through the firewall with the little blue valve thing on it (cant remember what its called). Thanks guys
Edit: I also checked the connections and the soft vacuum lines inside the car going to the heater controls and they look good...
