There’s a door lock actuator (solenoid basically) that has probably given up the ghost. Fairly easy to access by taking the door panel off and the plastic vapor barrier. I did both mine (same issue as yours) a few years ago. I figured the other one was just a matter of time. You don’t have an immobilizer issue just a simple mechanical one.

Took the opportunity to remove the crap sound deadening material that has certainly fallen off the door skin and is laying in the bottom of your door soaking up moisture. Replaced w Dynamat and sprayed Waxoyl corrosion preventative everywhere. Door interior was corrosion free and like new.

Thank you!

Your welcome. I don’t remember any hiccups w this repair. I think I ordered the actuator rod clips just to be safe. Parts are easy to find in the PET. The PITA is removing all the door cover and hardware. I also spent some time getting to and lubing all the window pivot points and slides.

DB’s symptoms point towards a bad actuator is all. Very simple fix.
