This is the third gen ram forum. However, you have a vacuum issue. your system works with vacuum, and if you lose it thru a broken fitting or anything else, your engine isn't going to run right and you will lose your a/c heater controls. Do a search on the appropriate forum and you have a better chance of finding a specific answer.
