    So if I understand this right, everything worked fine until you forded 3 feet of water. But now when you push the button for 4hi, it just blinks and nothing happens?

    My 98 blazer does this about once a year. I have been lucky in that pulling battery cable for a few minutes seems to fix it. Not sure how pulling battery cable fixes it, but I drove it so little I haven't looked into any further.
