2002 Impala LS Electrical trouble

I have a 2002 impala ls. I have multiple problems. 1st trouble is that when trying to lock the or unlock the doors, only the drivers door will lock and unlock, using the key fob or the door lock its self. It does sound like the other doors are trying to lock but they don’t . You have to do them manually. The 2nd problem I have is that sometimes the lights will go on , on the rear view mirror and the car will not start. I have to undo the battery, negative side, and then reattach and the lights will go out and I can start the car. I took it to Auto Zone and no codes came up. I am hoping that these problems are related and that it’s a single component causing these problems. Could all this be caused by the BCM? Any help will be greatly appreciated.

Thanks!

2002 Impala LS - Headlights keep burning out - frying wires. Replace bulb quite often, every two-3months. Is this a electrical or fuse problem???
