door locks unlock by themselves

Not a battery problem in the remote, does this happen mostly when its raining or wet out? Could be your disarm switch in one of the doors causing the problem

replace the battery in the key fob

It doesn't matter if it's wet or dry. The doors are always latched tight so it's not that the computer thinks the door is ajar. Where is the disarm switch? Would the body control module have anything to do with it and if so where is it? It must know when we are slowing or stopped. I've read about a key fob module behind the instrument cluster up high by the windshield but I wasn't sure if that could be it so I didn't tear into it. I pulled the door lock relay from under the hood and of course the locks don't work then. I don't think it could be a faulty relay intermittantly switching to unlock the doors because it only unlocks and doesn't lock them randomly. Thanks for the help guys.

The door ajar has nothing to do with the disarm switches, they are located in the drivers and passengers front doors, mounted on the key cylinder. The best way to check these out is to use a scan tool and monitor them as it is happening

How hard is it to change the disarm switch? I can see where it may be just setting of signal because its faulty.
