I know you think it is vacum, but it sure seems more like it's electrical. When the air starts to come out of the center vents on a/c mode it is all of the sudden, and it doesn't matter if the car is moving or at idle the whole time. If it was vacum would it work on e/c and not on a/c? This problem has had me stumped for quite a while now.
Thanks for your advice!
