Hi, I’m Mike from 1A Auto. We’ve been selling auto parts for over 30 years!

Open the door. To remove the master window switch we're going to use the plastic trim tool. You can get these from 1AAuto.com. Otherwise, you'd have to use a flat bladed screwdriver, and you could damage your trim with the hard metal. These are nice, soft plastic, and then kind of get underneath here, it's a little tight fit, and kind of slide it to the middle. There's a clip, we're going to push in this way, and at the same time pry up to pull the master window switch out of the door panel. Put this aside here. Now you can unlock the connector. There’s a tab here, push down and pull out on the switch to pull it out. Put the master window switch aside.

We need to remove this little door handle pull. This little pocket here, where your hand goes. Use the plastic prying tools to kind of go underneath to kind of catch the metal and then pop it up, just like that, and if this side doesn't come, you have to do the same thing, there's a similar clip, pop it up, pull it out, see what you were doing is you were going underneath, pushing in on this metal tab to unlock it.

To remove this black trim cover, take the plastic prying tool, reach in here, just pop it out, and pull that right out. You need a small flat blade screwdriver to carefully open this little door here to expose the screw that's behind it. Use a Phillips head screwdriver to remove the screw. Take the plastic prying tool, there's a slight opening just above the lock, push the plastic prying tool up, and then pop it up off, pull it down so it pulls down from this one. That needs to go out this way, and then you'll have to move this. So you're unhooking it by going this way, and then you're just feeding it off the lever.

To remove this push clip, actually push in on the center. It unlocks it, and then you can take the other side of your plastic prying tool and get underneath it and pry it right out, then to reuse it. Just push it right back out through, and put that aside. Remove the Phillips head screw that was inside our opening for our little cup here, pull handle. Using a Phillips head screwdriver.

The rest of the door panel is held on with clips along the edge. As you pull this off you will need to unplug the courtesy light that should be the only thing that is plugged into the door panel. You just kind of reach underneath, and if you need to, you can use a plastic trim tool, but there's a little bit of a finger hold here I can get it in, get my fingers in, and pull out. And we're going to lift up off of the steel part of the door. The door panel kind of hooks around the top, so lift up and straight out. And the only thing plugged in, I can turn this, so I can see it, is the courtesy light. You’re going to push in on the lock, pull it right out, and we'll put our door panel aside.

To remove the door handle and lock, there's a 10-millimeter bolt here. Remove that, take the bolt out, and pull this off. Slides out of the steel panel. There's a hook here and a hook here. Flip it over. The door opening handle is this green one and it's going into the handle there. We can pull it pulling out the plastic. Just pop it straight out and then when it comes out, you'll just push the cable up and out. And then for the lock one, it's the same thing. We're just going to push it up and out and then unhook it.

To remove the vapor barrier, it's stuck to the door panel with butyl tape. It's forever sticky. You want to take a razor blade and sometimes you just kind of have to gently pull it and then cut it a little bit. We'll get it to separate. You should be able to reuse the vapor barrier, and it will restick to this butyl tape. Just work your way all the way around, peeling and cutting it. Just going to feed this harness out of the opening here. Be very careful. You can lay it sticky side up and reuse it.

There's two actuator rods inside here. So the one with the yellow moves whenever you pull the door handle. The red one is for the lock cylinder. So reach down. Unlock the red one. Push it up and then pull it out. Pop this cap off with a plastic prying tool. There's one of the T-30 torx screws. We need the plastic prying tools. Here’s the lock cylinder assembly.

The lock cylinder's going to go in. Push it in place. You're going to hold the lock cylinder by hand and then tighten the Torx screw. Put the rubber plug back in. You're going to reach up inside the door and go for the red one here. We're going to push it into the opening and then push that down. It'll lock in there.

You're going to reinstall the vapor barrier. You can tell by the orientation of the holes which way it goes. So these two holes match up with these two here, and then these two openings match up with these two here. So I know that'll go up and also the slit there is to go around the cables. We're going to feed the wire through for the courtesy light. I'm going to start in this corner and this stuff is just always sticky. Put it back in place and just push it down. It'll want to stick to everything. I'll lift up the cables underneath, kind of line it up with the holes and just go along the outer edge, and push it right back in. I mean, don't be worried about getting it perfect. That's good enough there.

Reconnect the inside door handle with the lock one. So, the white one went in the other one. It just hooked in and then push right down in. The green one that hooks down in place there. It looks like this actually is broken a little bit it. It'd have a have kind of a tab over it that would lock it. Push it down in place. Just like that. There's two tabs here, they're going to go in to the door panel this way. Push it down. There are two openings in the handle. This one is for when the door panel is on and the screw will go through that, and the capital go over it. This one is the one you access with the door panel off, and the 10 millimeters self-tapper will go in here.

If one of these clips get stuck, you can just take a trim panel tool, pull it in here, pop it out and put it back in your door panel and reuse it. This went in down here—kind of push them in place. Plug in the courtesy light and there we go. The top of the door panel is kind of curved—it's going to hook over the metal frame, so I'm going to start by going up in here. It doesn't matter if the window is up or down. Hang it over it, and then we'll get it in place. Make sure that your master window switch harness is accessible, and now we can push it into place on the clips. It will snap into place. Just go around the door, and push them in place. Put a push clip back in.

Reinstall the screw that was under the door pull handle. Reinstall this door handle pull, the arrow points toward the inside, push it in, just like that. Reinstall this cover. It has a hook that's going to hook into here in the black plastic, so we're going to lift that up and slide it this way. Get it hooked first, and then push this in and we reinstall the screw.

Reinstall this black A-pillar cap. It just slides in place and then snaps in. Put the harness back in. It will click when it locks in place. There's a tab here that will slide underneath, and then this metal tab is going to push into this opening here.
