I have a 2001 town and CountryLimited and this evening while driving down the road the power locks just started locking. I was traveling around 60 mph for at least 5 minutes when this started happening. The doors are already locked but it was if someone continued to try to lock the doors. When I got home I disconnected the battery for 3 or 4 minutes and this did not help. They continue to do this even with no key in the ignition and sometimes they do it several times back to back. I actually cannot keep the vehicle unlocked because it continues to lock by itself.

 

to correctly figure this one out U will need a dealer scanner to see what door lock is staying open or what have u and then fix it.

 

Now it seems to work fine. It was raining pretty hard Saturday and we were in and out of the van. Maybe one of the power doors did not fully close or completely lock.
