<VV> Seeking Expedition suspension advise NO Corvair

[Grant Young]

My daughter's 2010 Expedition rear auto-level suspension has stopped working and is
in the lowered position. The owner's manual does not have much information and does not show the fuse
or relay or the location of the solenoids, pump, etc. Just hoping there is someone
on our list who has solved such a problem, or knows where to start looking. They 
planned to leave on a trip pulling a trailer tomorrow and there is probably
very little chance the Chrysler dealer who sold it and carries the warranty will
be able to fix it in time. It was once stuck in the lifted position after that
dealer rotated the tires without disabling the system (which can be done with
dashboard controls) and it had to be taken back for "repair" about a month ago. It 
has worked okay until yesterday.
Thanks much,
Grant
