My power door locks have not been working for a while now. When you press the lock/unlock button inside the car you can here the BCM click. When I use the remote to lock the car it locks the driver side door but unlocks the passenger side. So I was thinking the problem is the BCM. I bought a used BCM recently and tried to install it. As soon as I plug in the wire harnesses the alarm starts to go off and the car will not start or do anything. I have read a ton of threads and cant seem to find any help so far! Any help would be awesome guys!
