If not how do I fix. How do I also fix the driver side so it is not 1/4 lower than other side. When I turn off the car the air ride system lowers, but not all of the way. The driver side of the car is 1/4 inch lower all of the time on or off.
The air suspension does air up and then vent the suspension to a given ride height when the ignition is in the, "ON" position and then will hold for about 40 minutes.
Damage can occur if the air suspension switch, under the glovebox in the right kick panel, is not turned off when towed or jump started.
One of the main components that can control left and right suspension height differential is the Gate Solenoid. The outer shock air pressure increases which decreases body roll. The Gate solenoid is located in front of the A/C condenser. Other than that a fault might be occurring in one of the air shocks it self which each have a control solenoid. They are not servicable and must be replaced as a unit.
The best thing to do at this point is to get the trouble codes pulled. This will give you a better idea if there is an electronic fault. If no codes come back there is a mechanical fault. Any Advance Auto or Auto Zone will pull codes for free. They will have a brief description of the problem. If nothing shows up you have to visually inspect the system for loose or broken air lines and/or a failing air shock or other sources of leaks or ride height mis alignment.
