99 ML320 The power locks have a mind of their own, Any Ideas?
 

as I am traveling down the road the door locks will start locking and unlocking or will try to re lock themselves after it is already locked, while this is going on, the power lock switch on the center console seems to be inop.
Also sometimes when you unlock to door with the key the flashers will start flashing, and I have to get back out of the car and turn the key in the door one more time to get them to shut off, are both these symptoms caused by one thing or am I dealing with 2 diff. problems?

Possibly one of the switches which tell the computer responsible for locking that the doors are closed is bad, so a switch in one of the door latches. Easy way to tell is get it connected to a shop computer that can monitor the switches.

Thanks for the response
