doors unlocking by themselves
 

2005 Nissan Titan. The door locks keep popping open so the doors do not remain locked. Even when the truck is turned off and the doors are unlocked it keeps making the popping sound like you're unlocking them. Also, the button works to lock the doors but not to unlock them. I think it may be due to moisture getting inside the door. A couple of weeks ago I started having trouble with the driver side window not wanting to go up. Both things happen after it rained. The driver door is a replacement door. Would greatly appreciate any feedback.
