My wife’s Saturn Vue does not have any heat (floor). There is plenty of heat, through the vents and defroster, but none on the floor, regardless of the setting for where to direct the flow of air. Any idea on a possible cause for this? You can hear air being redirected when switching the output selector, but it never outputs any to the floor. When the selector is set to the floor, the bulk of the air is directed to the vents.
The most likely cause is a vacuum hose inside the dash panel that has become disconnected. Or, it is possible that a servo motor has quit.
