My odometer stopped working. I know that the BCM has been exposed to water through the plugged drain line of the sunroof, so I removed it, dismantled it, and attempt a repair.
This is part 1 of 2. In this part, I find the faulty component, research its function and availability and discuss the procedure for final repair. At the end, I await arrival of a new component from the UK. To be cont’d in part 2.
Here is a link to a follow up video working on the speedo to reset mileage for coordination with the BCM:

Hi! Did you ever get to film part 2? I have the same exact issue with my 08 Hummer H3 BCM. I'm unsure whether or not I should just replace the BCM.
