Hey every1...I just signed up on this forum and have a technical question. I have a 98 tour SE 2.5 ltr. and my interior vents only blow out of the defroster. I have already checked out the FAQ and searched and saw that there are two "vacuum diaphragms" under the dash that sometimes form loose connections. I checked the easily accessable one and even pulled the stereo and lower dash apart to check the second one and all the connections were good. I did notice that they have absolutely no vacuum going to either one so I assume the vacuum source off the motor is bad. Does anyone know where the vacuum source originates and/or have any pictures of where I should start?? THANX
