i am glad you are finally sorted. sure was one heck of a journey to find your solution.

 

Thanks. This has been a thorn in my side for almost a whole year now. I still have to sync the tire sensors. They were replaced last year but they use the same radio receiver on the BCM as the key fob so the shop wasn't able to get them to sync back then.

I was going to take it over to the dealer to show them that yes, it is in fact possible to put a used BCM in a Hummer but the two gentlemen who told me to go away no longer seem to be working there.
