I got a look at the car today. The passenger side trunk well has about 2" of water in it and has ruined the central lock module and the alarm module. The connectors are corroded with some pins broken. The mechanic was puzzled that so many of the functions were still working. I suspect that the modules might still be good, but the connectors are messing up the system.

Does anyone have some experience with these parts?

I'm looking for the parts and connectors, so any help is appreciated.

As the repairs proceed and we locate the leak I will post for posterity.
