Car Will Not Start problem #2

Special acquisition module (sam) my car would not start the mercedes roadside came out and started the car and I took it to the dealership for diagnostic. Upon review the dealer stated the sam module plastic cover had water drops on it. They also stated the male and female connectors to the module was corroded, and I would need a new special acquisition module (sam) at the cost of $1590. 00. They ask if I had left the windows down, but I had not the inside of the car has never been wet, but I did notice everytime I went to the car wash the information system was showing alerts I didn't recognize. My concern is even with a new module if the old one got wet and it is clear the water is coming from underneath the car what will keep the new module (sam) from getting wet. Something is allowing the (sam) module to get wet from under the car.
