View Full Version : heater core vacuum lines?
07-22-2010, 09:44 PM
well, i was doing some work on the 'ol GA and ended up taking the vacuum lines off the heater core (the multicolored ones going from the back of the HVAC control to all over the heater box), and like an idiot i didnt label them or anything thinking i wouldn't have them off that long and would remember where they went. and now, a week later, i go to put them back on and have no idea where each end goes... so my question to you guys is does anyone have a pic of the dash out of the car with all the vacuum lines in? so i can try and follow that and figure out this little set-back...

Wish I could help. I'm trying to figure out how to put wires and hoses how they are supposed to be, instead of all sloppy and all over the place since having the head gasket and intake manifold gaskets replaced. :(

Is that it?
lol I held a mirror in there and shot a pic thru the ACC plug door, but I'm not ready to take that apart anytime soon... Won't it be different for different models?

those are the HVAC Vacuum lines, if am remembering this right that is on the mode selector, those vacuum lines go to different small vacuum pumps on the HVAC unit that opens and closes the doors to change the direction of the air flow.
