[DML] Re: Mode switch

["Toby Peterson" <tobyp@xxxxxxxxxxxx>]

Chris - You might want to have a look at the vacuum actuator that 
this position supplies vacuum to for its function.  Perhaps the 
vacuum line to the actuator is cracked, or the actuator has a torn 
diaphram?  Often, when the diaphram on the mode switch goes bad, you 
will get a vacuum leak at several positions.  However, since your 
switch functions flawlessly except for the one position, I am 
thinking that the line or actuator is at fault.
