I need help. I have set my options in the DIC to autolock both doors when you start driving and then auto unlock both doors when you pull pull out the key. The problem I am having is that both doors will lock with the DIC or the key fob but the passenger door never unlocks with the key fob or the setting. Is the motor going out or am I not setting something right. There are no codes showing at all.

The door lock module is probably gone. The dealership replaced mine under warranty, but I was told that it is fairly easy to replace. The funny thing is that even though I was having problems with both the drivers and passenger's lock, the dealer tech replaced just the drivers which appently, fixed everything.
