I have an '87 Lincoln with air suspension. When the temperature drops to around freezing, the front end drops all the way down, whether I am driving the car or it is parked. This happened late last spring, then was fine all summer. Now that it is cold again, its happening again. I have the automatic levelling turned off right now [switch in the trunk], but if it turn it back on, the strange behavior returns.
I don't think this is a water freezing problem because I hear the compressor run, when I start the car. It runs for a long time to no avail -- the front end remains down. Eventually it is cut off by a timeout and the suspension warning light comes on. At least its not water freezing the compressor since it runs. Could water be freezine in the air bag solonoid valve or freezing the vent system valve causing all the new compressed air to vent immediately?
My gut feeling is that the computer is somehow affected because there are other unrelated problems like the Distance to Empty gets confused and displays erroneous values. The windshield wipers park and then immediately unpark on the glass. These latter problems are not related to the temperature, but may be related to the levelling problem if the computer is going bad.
How could temperature affect the automatic leveling? Is it the computer or perhaps the level sensors? How can I test this or what should I replace? The front air shocks were replaced at the end of last cold season to no avail.
This is a weird one ;-)
