Lexus GS Door Lock Failure

I've got a GS too, and that sounds familiar. Before you tear everything apart, check the wiring loom where it passes from the body to the door. They're known for chafing and broken wires. Any warning lights on the dash?

Thanks! Where exactly can I find this wiring loom? What damage should I look for?

It's usually behind a rubber boot between the door and the frame. Look for cracked or split insulation. Honestly, though, I took mine to a shop. Best 95€ I ever spent. Could save you some time, and potentially make things worse.

Thanks for the recommendation. Going to the workshop was the right move, as you suggested. They found a defective cable connection and fixed the damaged component quickly. The problem is resolved. I appreciate your suggestion!
