Hi, I have bought GMC Envoy and I have had some problems with BCM so it was said it needs to be replaced. I need to buy a new one BCM but as I do not have any local dealer in my country (Slovakia) it is very difficult for me. I have found a lot of BCMs on ebay for example but no one have the same P/N number as is on my wrong BCM and I am not sure if it is important or not. So I would like to ask if it is possible to replace the BCM with P/N number 15135466 which I actually have in my car with any other BCM with another P/N number? Can you advice me something? Photo of my BCM is attached. Many thanks, Silvia

I am not sure what that part fits, but the manual shows a different number for the 6 cylinder.

I am attaching the info needed to replace the part and the part number. Plus, the process to program the BCM when you get it.

Also, here is a guide that will help with replacing the BCM in a similar vehicle:

Please see the info below from the manual.

Let us know what questions you have.

Thanks
