I'm just going to hit the dome lamp override switch to shut off dome lights, just so we don't run the battery down. Open up your door, and using small flat blade screwdriver or a small trim tool, remove a couple panels: one in behind your door handle—just twist lightly and pull that out; there's one right back in here, right in the middle—pull out and off; then the door lock knob, pull up on it lightly, and try and pry this center clip out at same time. Comes up and off. If you have good fingernails sometimes you can just pull up and off on that. You could also use a trim tool available on 1aauto.com. Put it underneath, pull straight up, make sure you pull up on the front. Somebody was not that careful on this one, and you can see they actually broke off the tab from the trim. Then you'll want to disconnect your power window switch, just a little tab here. Pull and disconnect. Then we'll remove three 10 millimeter bolts: one here and then two down underneath where your door pull is. 10 millimeter bolts, remove them with a 10 millimeter socket ratchet and extension. A lot of times these ones won't come all the way out, and that's okay. You can retrieve them when you get the door panel all the way off.

You'll want to use a trim tool. Once you get in there, you can see in behind there and see where the clips are. Got one here, roughly here and here. Pull out firmly, and work your way around. Then my bolts have popped out here, so I'll make sure I collect those. Once I'm sure I'm all the way around, lift up, and out. Then on here there's a couple of little tabs. I'm going to push the tab, pull out a little bit, twist it around, push the other tab. Push that through and out, and my door panel comes out. You can see there's actually clips on the padding here. It's still clipped on in a couple of spots. Just push those off.

To pull this vapor barrier off, it's got some butyl tape on here. Sometimes it will peel off really easily. If it doesn't, I've got a razor blade here to help to just cut it off a little bit. There you go. I'll put this aside so it doesn't get destroyed.

Before you take the door handle off, you've got to remove or unhook the clip that's on the actuator here. It's this yellowish orange looking clip. It's got a little tab. A small, flat bladed screwdriver will push it open. It will pop off.

We're going to take our plastic trim tool—if you don't have one of these you can get them from 1AAuto.com—and we're going to pull this rubber grommet out. Put that aside so you don't lose it, and remove the door lock actuator with a T30 Torx. Now with it loose, we can go inside the door and disconnect the bowden cable for the door handle and the wiring harness. With the door lock actuator loose, I'm going to pull it out.

I'm going to undo the actuator cable or the bowden cable, the door handle first. I'm just going to squeeze here and squeeze the other one working around and squeeze it. Just like that and pop the end of the cable off of this and put that aside. I've got a tangle in the harness here. Get that out of the way.

The next thing to do is to pop this lock off of here with a flat bladed screwdriver. It's going to come up pretty far. Once it's unlocked, it should be really loose. Just comes right off. Slide the actuator out. Maneuver it out of the door. It's got a long actuator rod on here you have to fish out.

That's our door lock actuator. Our door lock actuator is working okay, so we're going to put this one back in. You're just going to have to fish the actuator rod in there. All right, before you get too far, now is the time to connect the connector. As you can see that lock on there, there's a couple of pins on either side of the actuator that those locks are going to go into, so you slide it over and push down as far as you can go. Then when you push the lock down, it's going to pull it the rest of the way in. Now that's locked. It won't come off.

Reattach the bowden cable, put the ball through, and push this lever in a little bit so it catches. I'm going to clip it in. Now we're going to feed that actuator rod up into the door. You have to reach around with your hands. There it is. Get this sort of close. I'm holding it in from behind with my hands so it's not like moving around on me. I've got my T30 torx bolts that came out. I'll thread these back in. get the holes lined up.

This is your child lock. There's a little diagram for it so this is unlocked. The door handle will open the door from the inside. If you don't want children to open the door from the inside, you can take a screwdriver and turn that so it's horizontal like that. Now I've got these started, I'm going to grab my T30 Torx and my socket and tighten them down. I'll reinstall this grommet. After the actuator is installed, you need to reconnect the actuator rod to this little yellow clip and try to get it straight up and down. Place the rod in there, and then if you just sort of roll it up and over it will clip in.

Now we're all set working inside the door, we can reinstall the water vapor barrier. Just going to feed the wires through, sort of find the general area of where it was. The butyl tape on there was still pretty sticky, so just kind of push it back down.

You have these longer, larger basically kind of teeth that hook into the square holes down there. Preliminary line everything up. Just make sure your harness goes up and through, and then reconnect your door handle cable in. and pull it out, push it in.

Again, just make sure that that harness is up through. You want this groove to go into the channel here, so lift up. Lift up, push down, and make sure your door lock is up through, your harness is up through, and then you should be able to see it nice and close to the door. There's a large line of pin up here. Once everything is good it'll go in about that far away, and then you can just set all the pins. You just need a pair of pliers, reach in, bring your lock back up. Put your three 10 millimeter bolts back in. One here, and then these two, and load into your socket. If you put some tape or painters tape on it might help hold them in place. I'll just put those in place. Reconnect the switch, feed the harness down in, and make sure you put this in correctly. Then your three pieces of trim, the one in behind the door handle, snap it in place. This one can just go down in place. This one make sure that the little tab is out. Put it down on, lock into place. That's all set.
