Im currrently restoring a '80 chevy 4x4 dually with factory a/c, the problem Im having is it only switchs on normal and bi level the rest of the settings wont work, I took and hooked vacuum up to each line without the switch and everything works fine so I think my switch is bad plus when its on the settings that wont work you can hear vacuum leaking from inside the switch, I took it apart but still couldnt get it to stop so I found one in a junkyard but it was the same way, does anybody have any idea where to get a new one like this or even make this one stop leaking, I can find the style like the 80's but nothing for a 70's model, here is a pic of the switch I need
