Please find the internal diagram of the driver side power door lock.

and also to have a detailed troubleshooting the locks please visit:

In my mind, cold making it worse would indicate that the actuator is bad. Think about it. Cold makes everything contract thus making more friction. When you use the key fob or the switch, you hit it until you hear it lock. The auto lock is a short signal sent to the actuator and evidently the actuator is weak or binding slightly causing the actuator to not fully lock the door. *shrug* That's just my opinion though.

    First remove the inner door panel. I'm not going into this. There is an excellent writeup at Mini2 on this.

    There's not a whole lot to take pictures of.

    First look inside and get acquainted with the tight space you're going to be working. When looking toward the outside edge of the door (the part where it latches) you'll first see the rail the window rides along. This will be in your way and it is possible to remove, but not necessary.

    Just behind it, sort of wedged into the inside corner of the door is the lock actuator assembly. Just opposite it is the backside of the door handle.

    There are 3 steps to the removal.

    1) Removing the 2 door opening cables, the lock indicator bar, and the electronics connector.

    2) Removing the outside handle (drivers side door only).

    3) Removing the 3 screws holding the actuator in place and wiggle it past the window bar.

    Step 1

    As you look inside the door, to the outside of the door will be the cable that opens the door from the handle. At the bottom right corner of the actuator is the end of the cable. Pull the cable down for slack and then towards the front and up at the same time to disconnect. Remove the cable from the holder above it and one cable down.

    For the inside cable, you have 2 options. First and easiest is leave it connected and disconnect it from the inside handle and just thread it through the door and remove with the actuator. Otherwise, look at your new actuator (you do have it right?) and you'll have to open the flap and lift it off. You may as well take it out, I doubt anybody could get the darn thing on the mechanism inside the door.

    Removing the electronics cable is tricky. It's hard to see and I broke off both sets of clips that hold it in place. Don't know what I'll do to keep it on. Probably glue it once it falls off once. The clips are fragile.

    Finally, the bar that shows the door unlocked or locked, just pop it out away from the actuator and remove from the car.

    Step 2

    Probably the most difficult part.

    There are 3 screws that hold the door handle in place. They are right where you'd expect them to be. The one toward the rear has a hex head (10mm) and an allen wrench head (5mm). Back it out all the way.

    The one near the outside edge of the door is allen only. If you have a long enough allen wrench, I'm talking medium length screwdriver here, back it out. Otherwise, a t-27 torx head will work in a pinch. There is an access hole under the rubber cover near the upper-outside edge of the door. Remove the grommet and have at it. Back it out until the handle come free. Gently pull the handle away and the cable comes with it.

    The third screw is torx t-25 and is under the rubber grommet on the outside edge of the door (where the door strike is) Just above 3 t-25 screws. Look at the picture. Remove it and the lock tumbler is free. It may not come out now due to the actuator holding it in place.

    Step 3

    Remove the 3 t-25 torx screws holding the actuator to the door it includes the strike so when those are free, it will start to fall inside the door. Make sure your window is fully up.

    If you look inside the door, the rail for the window has a bolt coming up from the bottom of the door. If you loosen that bolt (10mm hex), you can slide the rail about 1/2" toward the inside. This will give you just enough room to wiggle the actuator out.

    BE CAREFUL HERE. If you force the actuator, one of the edges could leave marks in the door body panel. Don't force it. You will have to angle it slightly and drop it down to the widest part of the door and just work with it and it will come out.

    Once it's out of the car, remove the cable for the inside door handle. Remove the white clip that held the cable for the outside door handle and you'll have to remove the bottom clip that held the outside door handle cable at the bottom.

    Installation is the reverse. Be sure to tighten things appropriately.

Power locks don't work with remote or control from

The door lock/unlock input from the driver's key switch goes to the Door Multiplex control unit (main switch), the Door multiplex control unit then sends a signal on the BUS (CAN) circuit to the passenger's multiplex control unit; the passenger's multiplex control unit then controls all the door locks. The passenger's door lock key switch inputs to the passenger's multiplex control unit, if the locks work from the passenger's side key switch but not the driver's side key switch, the most likely cause is the driver's multiplex control unit (main switch) not sending the signal to the passenger's side multiplex control unit. This could also be the drivers side door lock actuator. Hope this helps!
