Hi,

Make sure the air ride switch is turned on in the trunk compartment. Next, you will need to check the wiring for opens/shorts. You will need a DVOM(digital voltmeter) in order to test wiring. There is also the possibility of faulty air suspension switch(located in trunk compartment on left hand side) or a faulty ASCM(air suspension control module)(located behind right side of dash-remove lower instrument panel sound insulator below glove box to access ASCM)

Here are tests that you will need to perform in order to properly diagnose and correct problem:

Here is wiring diagram to help out with above tests(in 3 parts so you can read it better):

You really need to do the above tests. Although it might be the switch or the ASCM, just swapping out the parts, you are taking a chance on wasting money needlessly. It could just as easily be a short/open in the wiring.
