Passenger door sounds like the door lock is locking and unlocking itself automatically, even with car turned off. it has drained the battery when the car wasn't moved for 2 days. the locking mechanism isn't actually closing and opening though. any thoughts will be helpful!

okay this how you do it you lift the handle up on the car and you move it back and it should go back only when the handle is up
SOURCE: 1992 Subaru Liberty wagon - cannot lock front passenger door.
Check the alignment with the door pin. Might be out of adjustment and will not let the door close all the way. That will cause the lock to not be operable. Good luck and have a great day.
Replacing the drivers door switch most often takes care of this problem. Due to the cost of the part have a dealer confirm this.

Driver door lock switch

Front passenger door lock switch

Door lock actuators in each of the doors

Door lock system fuse into the BCM (BCM D 25A fuse)
Door Lock Operation
When the BCM detects a transition of either of the door lock switches to the LOCK position, it switches the door lock actuator lock control circuit to voltage. Since the lock actuator unlock control circuits are at ground potential within the BCM, the door lock actuator motors transition to the Lock position.
Driver Door Unlock Operation
When the BCM detects a transition of either of the door lock switches to the UNLOCK position, it switches the driver door lock actuator unlock control circuit to voltage. Since the door lock actuator lock control circuit is at ground potential within the BCM, the LF door lock actuator motor transitions to the Unlock position.
The driver door lock actuator unlock control circuit is a dedicated control circuit used only for the driver door lock actuator motor. This is done so that the driver door may be unlocked by itself using a keyless entry transmitter or an automatic door unlock function (if programmed).

This video on testing computer controlled door locks on a Subaru , doesn't matter . test yours same way > The BCM controls your door locks .
Are all of the power door locks inoperative from both door lock switches?

My 2012 Legacy is doing this exact thing. Front passenger door. It hasn't drained the battery ( yet ), thank my lucky stars.
