THE
REAREND IS DOWN OVERNIGHT
Don't
worry, this is a problem an air suspension equipped car owner WILL
encounter sooner or later if they own the vehicle long enough. As with most air
suspension problems, they can be easily diagnosed and repaired without having
to go to the dealer, if the owner is familiar with how the system works.
One
of the most important things to remember about a air suspension equipped Ford/Lincoln,
is that the system has a separate module or "brain". The module is what
makes all the air suspension decisions.
This
system is designed not to let any air in or out of the front or rear struts unless
the solenoid on that strut has been opened by the module. These solenoids act
as a gate for air to go in or out of the strut and no air should go through into
the strut unless the solenoid has been opened by the module.
On
Ford/Lincoln vehicles, the module will "go to sleep" an hour after the
ignition is turned off, which means in essence, is disabling each and every solenoid
in the system. After this hour has passed, the module won't try to make ANY adjustments
until the ignition is turned on again.
With
that being said, if the car lowers after this hour has passed, most likely you
have leaking rear air struts. We recommend performing a leak test. Don't worry,
there is an easy way to do this test without even getting your hands dirty. Go
here for more info: LEAK
TEST
Keep
in mind that because of the rolling lobe design of the air struts/springs, they
will usually leak the worst while being driven. Because the system is automatic,
it has probably been leaking for 6 months or more without you even knowing. This
has already put a pretty good strain on an already old system. The sooner you
fix the leak(s), the more money you will save.
