Heater Control Valve on 90 A90 Q20V

[rob_duvalle@co.washington.or.us]

Posting for a friend who has a question about his 90A90.  He was replacing the 
heater control valve and noticed that the nipple on it was broken off.  The 
new valve has a nipple on it and he was wondering if on this model there is 
not supposed to be a vacuum line to it (meaning that coolant is always 
directed into the core).  He checked around and found a line in the dash that 
appeared to be capped at the factory.  Anyone been there.....?  

Thanks in advance for the help!
