i searched all thru the forums for an answer for this and cant seem to find anything. the issue i am having is that when i turn my a.c on, it blows out the vents like its supposed to, but it also blows out the defroster and if the sun is not out my windsheild will always fog up. my wife has the same car (1996 bmw 740il) and hers does not do that, so i know there is a problem with mine. i have bypassed the heater pump and the heater core and that has not resolved the issue. its really hot out and i want my car to blow out the vents on the dash only to help cool the car off. please help!
