Lexus LS door lock malfunction

Hey, that's a bummer. The symptoms point towards a door switch issue or potentially a problem with the wiring harness. Have you checked the door switch? Often, the cable or plug connection of the component could be defective. Also, does it affect all doors or just one?

Thanks for your advice. I didn't check the switch yet. Can you tell me where exactly can I find it? And what should I look for?

Alright, so the door switch is usually integrated into the door latch mechanism inside the door. You'll have to remove the door panel to access it. Look for any loose connections or damaged wires going into the switch. Given your description, it sounds like the cable or plug connection is likely defective. Frankly, without proper tools and knowledge, messing with the wiring can be risky, so maybe consider taking it to a workshop.

I appreciate the help. I took it to a workshop and you were right. It was indeed a defective cable. Repair cost me 95€. Thanks again!
