door locks and power windows don't work on 3 doors serial buss problem?
Hi everyone, I have a 2002 Seville that got wet in a flood up to the carpet. Everything on the car is working okay except for the passanger door windows and door locks, and the rear door windows and locks. The car doesn't talk to any of the door modules except the drivers door. U1161 - Loss of PASS Door Module SBI, U1162 - Loss of Rear Driver Door Module SBI, U1163 - Loss of Rear PASS Door Module SBI. I am guessing the seial data bus has a problem. Anyone have any experience finding and repairing the serial data cable. Any advice on this at all will be greatly appreciated. I am suspecting the problem will be at one of the splice points. All the fuses in both the front and rear have been checked and are okay. Rick

I had a similar problem after tipping over a martini on the drivers mat & under the seat. I has everything to do with the electronics under the dvr.seat. I was able to correct after doing the wiggle on the connections. I don't know what modules are under there. It looks like 2 or 3 are there. Make sure things have dried out well.
