It's been a while back . That lock was replaced they also replaced tranny. Bout same time
That's all that is in the history for this car from dealer and car fax . I know it got wet floor board was wet . But I pulled ECU checked it . Was dry. The bcm is right there I couldn't feel no moister around it. The water seems like it came from somewhere near or under the fan.i did all the reset computer and drove it . It will not shut off if you get it started. And before it start security light still flashing . And I have to put key fob in holder but if it starts it's without hitting the button it just will start when you hold the clutch for a while by its self. I have dump clutch shut it off. And take battery cable off to get the power off inside car I.e. the push button on light and warning lights on dash . It will throw a code u0164 communication HVAC . It will go away and come back as car is running or shut off. I took it to dealer for them to diagnose it. We shall see.it didn't do this till I went threw car wash . So I don't think it flood car I thing a seal around wind shield or wiring harness allowed water in.
