Need help with the underseat/floorboard electronics 2015 silverado

[Bobby Hale]

I'm trying to repair 2015 Silverado that has been in water up to the bottoms of the seats. Does anyone have a diagram showing the electronics in that area with part numbers? I'm going to replace all the wiring and any electronics I can find damaged by the water. The instrument cluster is inop so something in that area must control it. Any help would be appreciated. Thanks.

I try your dealership (part's man) ask for a print out of the area - wires /switches /ect. good luck

I'd bet 10:1 that the BCM got swamped. In years past it's been low under the dash, and console if it has one, mounted to the floor if I remember correctly. Up to the seats would've definitely put it or the wiring underwater.

Yeah I was thinking the bcm was damaged. Would that control the odometer and guage cluster?
