I have a 1970 chevelle convertible with air and I've been experiencing problems with the direction of the air flow. An example of this would be when I select defrost the air flows down to the floor. I can't seem to get the air flowing in the direction that I select on the panel. I know that the air flow is controlled by vacuum but I not sure if the vacuum lines are properly hooked up. I was wondering if anyone knew of a website that may post a diagram of the vacuum line connections. I would greatly appreciate any advice on the matter.

If you can't find a schematic on it anywhere, go to a junk yard and pull the control unit out and write down how it's hooked up. Or if it's cheap, buy the unit for a backup and cut the vacuum hoses then just compare at home.

Jamie for what its worth...I e-mailed you a pic of the vaccuum diagram out of a 72' manual. I dont know if its the same as a 70' but I sent it to ya anyway. hope this helps.
