Audi Repair: No heat, vacuum lines, heater valve

Question
I have 1992 100CS with 2.8l. I changed the blower fan for the heater.  Since changing the fan I have no heat, just cold air.  I am not sure that I have the vacuum lines hooked up correctly and have been try ing to find a diagram for them, but I do not know that this is the only problem.  I really need any ideas out there, it is pretty cold out!

Answer
Not that it's much help, but... Should have labelled the vacuum lines...  Now you either have to get a manual or find someone with the same type of car.  Sounds like the heater valve is not being activated; but I don't have a clear picture or a diagram of the connections.  You could try some of the Audi forums for help...  Let me know what you find,  Jan
