are you using the same series wiring for everything? if you aren't, its going to be a huge mess.

I used the original S4 wiring, its all S4. The only thing that is S5 is the short block.

That connector looks almost like it might be the one that plugs into the back of the blower motor. Is is a 2 conductor? Is there anything connected to the two conductor plug on the side of the blower motor facing the firewall?

If that is it, it would explain why the HVAC does not work. It is wired such that if the blower motor is not operating, the AC will not come on.
