Hello again. I need help locating the vacuum source for the heater control unit on a 1986 Grand Wagoneer. None of the vent doors open. I checkd the unit and all ports and hoses seem fine. I believe there is an outlet on the firewall in the engine compartment but am not sure where it hooks up. This site has been very useful in the past but seems to have been overrun by a group of chowderheads who only seem interested in trading insults or selling non-related products. Is ther another site/group that these miscreants have not taken over? This is my 4th posting on this subject without one response. Please help. Jim
