Figured it out, apparently the vacuum source to the HBV should not be constant, that is why I wasn't getting warm air inside the car. So now I got one loose vacuum hose behind the car that has vacuum in it and not sure where to put it.
Is this thing perhaps related to the HBV operation by any chance at the back of the engine? Connector goes to it and it has 2 vacuum hoses going to it apparently but I'm not sure from where and to where.

https://puu.sh/vooSz/deb066a795.jpgI get the check engine light on shortly after I take off at low RPMs or if I go around the town at low revs but when I do a quicker acceleration it turns off almost instantly and stays off usually under my "usual" driving. Need to read the codes tomorrow or something but anyone got any wild guesses?
