Frontier door lock failure

I had something similar happen on my Nissan Navara. Have you checked the wiring harness where it passes from the body to the door? That's where my issue was. I had a broken wire there. It's a common spot for wear and tear.

Thank you for the information. Could you clarify if your symptoms were identical, specifically the inability to lock or unlock the door? Was there any other electrical malfunction?

Yes, the symptoms were the same. The door refused to lock or unlock electronically. No other issues were present at the time. I suggest you visit a workshop.

Confirmed; the defective plug connection was the issue. Repair cost was 95€ Thank you for your assistance.
