[DML] Re: Mode switch

["Harold McElraft" <hmcelraft@xxxxxxx>]

Probable causes:
rubber manifold split
hose disconnected
diaphragm not in correct position
diaphragm is damaged
mode housing cracked
plastic hose cracked
a vacuum motor is leaking and it just sounds like it is the switch

Be methodical as you test. Have you checked the switch on the bench?
