Re: [DML] idle revisited

Dale;
You can get a good idea of what the under dash looks like on page 7/3/0 of
the parts book. Part number 100752 item 7 has the diaphragm inside. ( It
is called Mode Switch). The lines come off it in one solid rubber boot with
all the line connections built in. It looks like you could never get it
back together but my went back in and connected really easy. Only two
screws hold the switch in, they go in from the front panel. The switch is
really not an electrical switch, it just send vacunm to the different
position to close or open doors in the fan air system. Depending on what
might be broken or just cracked when the right thing is selected you could
have a leak. Depending on how broken it is you can sometimes hear it
sucking air.
