Failed door lock cylinder switches on Dodge Ram 1500

Problem Description and Possible Solution
If the door locks intermittently lock and unlock without pressing the door lock switch, the door lock cylinder switches may need replacement. This may occur more often when driving in damp conditions like the rain or through a car wash.

rear door lock works off and on mostly off
When driving in wet weather only, the locks will unlock then lock doors again. Happened to me with the keys out of the ignition and left them in the truck and I had to break into it. I will be looking for a new door ajar actuator/switch with the water gasket part on it. Dunno if the lights in the cab were coming on too but hopefully it's a easy fix. Also the keyless entry buttons were not working.
