[MOPAR MIKES]

Working on 1968 Dodge charger AC heaterbox and do not know how to set the doors and levers on the side for the start or off position so everything functions as it should befor any vacuume is supplied from the switch . Should all the doors be in the closed position ??

Do you have a service manual? My 67 had pretty good information on how to adjust everything. But it was too long ago to remember much of the details.
