I HAVE A 94 CHEROKEE, THERE IS A VACUUM LINE COMING OUT FROM UNDER THE PASSENGER SIDE UNDER THE GLOVE BOX, HOSE COMES OUT OF THE BOTTOM OF THE AIR BOX WHERE IT OPERATES THE FRESH AIR RECIRCULATE VENT.. WHERE DOES IT TERMINATE? I HAVE SEARCHED ALMOST EVERYWHERE! ANYONE HAVE ANY IDEA? THANKS.

 

Should be orange and terminates at the a/c control head

 

it is a black hose... only about 14" of line, i will look there. Thanks so much dude.
