1972 AC Vacuum Line
My heater control valve will not close when I turn on the AC and I am in the middle of trying to determine why I don't have any vacuum coming out of my A/C slide switch under the dash. It appears that I have some going in but nothing coming out. The vacuum going is very week. So, I am going to put a vacuum gauge on the various points throughout the system and was wondering if anyone could tell me what readings I should expect on the vacuum gauge? Please see my picture below and if you can lend any insight, that would be greatly appreciated.
BTW, I am running a two port off the manifold - one is going to the brake booster, the other has a T that is feeding the transmission and the HVAC unit. Thanks in Advance, KellerMac
