Well, it looks like the heater hoses are hooked up...ummm. Any ideas guys??

If you have a working fan motor then I'd check the heater core hoses. They should be hot to the touch when the car is warmed up. If that the case and your still not getting any warm air its either your blend door or the heater core. The blend door is vacuum controlled, if its not hooked up then it could be closed off and you will only blow cold air. If its working then it probly your heater core. A good way to tell if they are bad is leaking coolant, typically on the floorboard or your windows will fog up uncontroably when the heater is on. Let me know what you find out.

Did you attach the vacuum hose to the heater control on the heater hose?

check the heater valve that's in the heater hose and make sure the vaccum is hooked up to it and check to see if the valve is seized
