It sounds like the BCM got wet here is the location. I would try to unplug it and let it dry out for a couple of days while checking the terminals for corrosion. Disconnect the battery first leave the doors open as well. If that does work try a used BCM

Upload pictures of the problem will help.

Please let us know what happens.

Cheers, Ken
