Q: Rear end leveling not working correctley on 1999 Cadillac DeVille

The rear auto leveling is acting wacky. When I stat the car it airs up and levels out then sometimes it will go way down and not come back up until the next time i start the car. After parking it will often lower down by itself with the car off. I check the ride hieght rods on each side and they are fine. Help.

Could be you have a air leak at one of the shocks or related air supply lines. The other thing possibly would be the ride height sensor out of adjustment or a bad sensor. I have seen the sensor bracket where it bolts down be loose and letting the sensor move around and cause the same thing.
