Vacuum feed to AC/Heater control panel on 1999 Durango
Does anyone know what vacuum line feeds the AC/Heater control panel on a 1999 Durango? Sometimes when I turn the AC on, all of the air flow is directed to the defrost vents. I have to turn the AC off, reach highway speed and turn it back on, in order to get the air to flow through the AC vents and not the defrost vents.
