Have a 94 lincoln, recently I have had a problem with the air suspension
deflating usually the rear and sometimes the front. It seems like this
problem has started only since it has turned cold. Sometimes I can hear a
hiss when vehicle is stopped and watch the suspension go down and when I
return to the car the next morning its up again?? If you have any clues on
this I would appreciate it

The suspension will go down when you shut off the car, exit, and have
all doors closed. It's just adjusting for the removed weight. If you
believe you have leaking air springs, turn off the switch in the trunk
and drive it for a while. If it falls then, you have actual air leaks.
It's usually the air bladder material, but sometimes it's the 0-rings at
the individual solenoids on the air springs.
I have a '94 Mark VIII and have had issues with the air ride system over the
years. It has over 156,000 miles. The first thing I would suspect is leaky
air bags on the front and rear. What I would do to isolate which ones are
leaking is to spray some soapy water on the bottom of each bag when they are
inflated. Watch for any bubbles that would indicate a leak. They are prone
to crack at the fold on the bottom of each bag with age. I would think that
when you come out in the morning and the car is up would mean that it is
either re-inflating or parked in such a way that the cracks are not opened
up. This would make it appear that they are lot leaking. Mine did just that
with the front just a few weeks ago. Some mornings it would be down and
others it would not. I sprayed some soapy water on both front struts and
found that the left one was leaking. Replaced it with a rebuilt one at just
a little over $200 with tax vs. almost $400 new. Now no more droopy nose in
I would suspect an 'O' ring problem. Why not take your vehicle
to a Lincoln dealer? They will connect it to a suspension system
analyzer that will direct the technician to the exact source of
