I Hate To Ask This

A 2007 van is going to have a lot of computer modules. Going by my GM experience ( I know, GM, yuck, don't hate me) there is probably a module for the powertrain, body control, IPC (cluster), air bags, ABS, anti theft etc. Any one of these getting water intrusion can cause all kinds of expensive problems. I'd call the insurance co. I've seen minor flood damaged vehicles get totalled at our body shop.
