moran75 Posted January 7, 2020 Share Posted January 7, 2020 Hi all my heat/air system has never worked properly, but that’s ok - I can live without either...not a priority ... BUT what I have done is break off the vacuum nipple at the heat door diaphragm...so I now def have a vacuum leak..and possibly others hence system not working. As I’m in no rush to repair everything , but want to avoid performance issues no matter how small or inaudible to untrained ear, how about plugging the ‘main’ vacuum hose from the T at back of carb...therefore isolating the whole heat/AC system ? is that feasible or would it create unforeseen problems? Thanks in advance kev Link to comment Share on other sites More sharing options...
64Rivvy Posted January 7, 2020 Share Posted January 7, 2020 Mine was plugged just like that when I got the car and didnt appear to cause issues. I'm just now completing a full rebuild and replacement of the heat and ac system so will be hooking it back up soon. 1 Link to comment Share on other sites More sharing options...
