Don't worry too much if you feel you may be in to deep. I just want you to understand the system so that IF you have to take it in to be repaired, you can ask the right questions so that you don't get charged for replacing the entire system, when only one piece is required.
If it started with large puddles, the would tend to confirm that the problem is water getting into the exhaust solenoids. These are located on the compressor to let air out of the system so that the level of the vehicle will go down.
These is also an air 'input' on the compressor, and a little bit of electronics in the area. So if water gets into the system, it can mess up the exhaust, or the electronics (solenoid). What the other expert was saying is that air vent really needs to be moved, so that there is less of a chance of getting water into the system.
I believe the relay he was referring to is the control relay, which is shown in the first schematic. Below are the two diagrams that show the location of the ALC (Auto-Level Control) system.
Let me see if I can find the system description for you, so you will have the "Big Picture" of how the system works, or is supposed to work.
