Ralph---The air movement to different outlets is controled by the the vacuum servos (motors) so I think you may have one or more of these that is not working--assuming that you are getting vacuum to them.If you have a vacuum gauge you can ck. vacuum drop at different settings to find the defective servo (servos) You can do this by inserting the gauge in the main feed line that comes out of the reserve tank in the engine compartment.
