You may have to check the vacuum control for the dash. They have a rubber diaphragm I think that controls the whole system. I think there is a thread on it in the forum on the DIY fix from one of the gentleman on here from about 6 months ago or so.
If you have a hand vacuum pump for checking each door control and none are leaking, that may be your culprit.
