When I first pick up my van from the dealer the light/
and servo did not engage.  I checked underneath and
one of the little vaccum rubber hose was cracked and
not activating the servo.  I replaced the little hose
and it has since worked like a charm.
Check the rubber hose first.  It is easy to brush off
and near a low point under the van.  It is also very
easy to replace.
