Driver side door wont lock

[RAJOD]

Over the past few days the alarm has been going off when I opened my door. At first I thought I forgot to lock the door.

But I had been locking the doors, just the drivers side door does not lock. The LR3 thinks its locked as the alarm sounds when I open it.

When I push the key or the center console lock button I can see the flipper on the door moving in and out. So its getting power to the mechanism.

We have been going through a huge thaw with tons of snow melting. Wondering if humidity is causing something to stick.

Any suggestions on fixing or debugging this.

Also, all other doors and tailgate lock fine. Its just he drivers door.

Same problem here. I sprayed the mechanism the best I could with WD-40, it will lock if I push the lock button on the FOB twice. If not, then the alarm goes off when I open the door just as you have described.

Sounds like you need the lock motor assembly. I've read they go bad sometimes.
