    Passenger door won’t unlock, central locking dead

    Central locking and drivers lock cylinder worked perfectly on my car until I unlocked it yesterday after traveling for two weeks. When I unlocked the drivers door, the lock opened but none of the other locks moved like central locking was dead.

    Passenger door lock won’t unlock from the outside. Drivers door will not lock from the outside but if I push the handle down to lock it, I can unlock it with the key.

    Trunk locks and unlocks fine but does not unlock when I unlock the drivers door.

    Seems like a central locking issue? The fuse is fine.

    Ok so I took the driver lock cylinder out. It’s afflicted by the standard cracked arm. I manually pushed the microswitch to lock the doors and nothing happens but I could hear clicking in the CLCU. I manually raised and lowered the fork that the cylinder rotates in but that didn’t lock or unlock the passenger doors. Any ideas of what to do next?

    Thanks​

    it was the blown fuse in the CLCU. I resoldered it and all the locks work like they should even with a broken drivers cylinder lol. What a nightmare to get to that control unit. https://www.rtsauto.com/two-of-most-...w-to-fix-them/

        Hello asking for help. None of my doors will unlock or open. I can’t even unlock and open the trunk. I replaced the CLCU and it still didn’t fix the problem.

        what can I do to fix this? It’s a convertible so it’s harder to rip the door panel off with the door closed.

        thank you
