Of course not!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
What exactly happened? Did you take a BCM out of another vehicle? With Global Communications, it won't work......All BCM'* retain the VIN of the vehicle they come from......putting it in another vehicle with a different VIN causes communication problems...
BCM'* are a pain in the *** when you replace them.......you have to be tied into a GM computer, and you have to know all the RPO options and make them available to the BCM during programming...if you make a mistake, sometimes you can't change it.....and God forbid, if you don't have backup battery power while doing this....
