Ok first of all yes I searched. Did not get any real clear answers. My fiancée cobalt is a black 4 door LS. I found a black 4 door LT with power options that hit a deer. I was planning on swapping the entire doors from the lt to the LS. My question is how do the power windows and locks work? I'm guess it has something with the bcm? I'm really not sure. What wiring will have to be swapped to make it all like factory? And if bcm is swapped how does that work cause I thought bcm's were vin specific? Does that mean there will new to be a reprogram if that's how it all even works??
