2003 Durango Door Locks / Keyless Entry

My 2003 Durango is suddenly (today) acting wierd:

The doorlocks will lock /unlock at random - particularly when the key is in the ignition and the engine is running.

Even when I remove the battery from the transmitter, the behavior continues.

Once I arm the security system, it behaves normally.

Could it be:

1. bad fuse?
2. bad wiring / short?
3. door lock activator itself?
4. ???

Appreciate your time and advice...

One more thing:

Sometimes after I turn off the engine, remove the keys, etc., the security system arms itself without being prompted.

Ideas?

The schematic for fuses, both inside the passenger compartment and under the hood, show no clear fuse for the door locks and/or security system.

Is there a fuse or link for these items?

I just found a TSB for this problem. I'll contact my dealer and see what gives...

My dealer replaced two (front) door lock switches today - and my warranty covered the expense completely.

So far, so good!

Even after the car wash!

Thanks everyone for the help! :icon16:
