Hi,
My power door locks will unlock but will not lock. Has this happened to anyone else? If so, how was it resolved?

It affects all the doors, and the unlock is functioning. Which is why I don't think it's a bad actuator. I can manually lock the doors and both the fob and unlock button on the door will unlock all the doors, but nothing happens when I press the lock button.

Suspiciously, it began when I returned from a three-week trip. My car was parked at the airport, and I needed to get a jump start. The locks haven't worked properly since.

The 12V battery in this car is smaller and less powerful compared to a normal car battery. How old is your battery? If it's already a couple of years old and it died completely and you needed a jump start I would just replace it before other problems occur. So I would check the battery health first.

Mine was checked when i had my car serviced and they said it was at 70 or 75% health and it was still good. Not long after that my car wouldn't start so I replaced it and problem solved. After I replaced it I plugged in my OBD scanner and it had some codes all related to low power circuit for the power windows, heated seats and parking sensors. I cleared the codes and they haven't showed up again.
