Re: A/C Heat Vacuum Hose Routing

I fixed the airflow issue- two of the cables were backwards. However, the vacuum is still working opposite. When "inside" is selected,(top lever fully to the drivers side) the vacuum valve allows engine vacuum to all the ports- the fresh air, cowl and heater water control valve. Move it to "outside" or further right and they all close.....
No leaks in my lines or actuators and I have a good 15"-20" at idle. Should work the opposite if I understand correctly, ie vacuum passes through the valve at all times except when it he lever is fully to the drivers side and it is "inside". Am I missing something?
