2007 Lincoln Navigator Air Suspension

I need help diagnosing the cause of my rear air suspension that fails every time it rains. The dealer has replaced the compressor, both rear air bags, a strut and 2 selonoids. They have no clue how to fix the issue when it rains after more than 12 service visits. Does anyone know what is wrong? Thanks.

Without knowing if there are DTCs stored, one overlooked component that can cause this symptom (especially when wet and rainy) the driver door ajar switch. Remember, the suspension wont work with the door open.
