Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.
In this video, we're going to show you how to remove and reinstall a regulator rail. This is if the regulator or the motor still makes noise and still works but the window is not going up and down. Usually it's just the regulator rail you need to replace. Tools you'll need include a small, flat blade screwdriver, Phillips screwdriver, a 10mm socket with a ratchet and extension.
To remove the door panel first use a small screwdriver, carefully pry up here. Pull this corner straight off. Then you want to go under here. Pry straight up firmly on your switch panel. Turn it over and there's a button right here. Press that button and disconnect your switch panel. Use a small screwdriver, and there's just a little trim button down here. Pry it up. You can see there's a Phillips screw right there. Just fast-forward as I remove that screw and then pull that door pull cup up and out. It's fragile. You see mine is broken already so it makes it a little easier to come off.
Basically there are four tabs. You want to pry in between this back part and the tab and pull out on the bezel at the same time. Pull it off. Grab hold and pull firm on the bottom. Lift the panel off the bottom. Now you want to pull the water shield back. Start by taking the two screws off that hold the small speaker near the door handle. Then take the screw out in the middle of the door handle. Slide it back. Then the two screws that hold the bracket in the middle of the door, and then slowly and carefully pull the water shield down to give yourself access to the inside of the door.
Next you'll need a 10mm socket with a ratchet to remove this brace. We'll fast-forward here as we just remove those four bolts and that brace. These window regulators are cable-activator or cable-driven. Usually when they break you hear a popping and then a grinding noise when you try and activate your window. Basically you can still hear the motor run but the window doesn't move. When you get to this point, usually what you can do is just grab hold of them with your hand and move them up and down by hand. You want to move it to a point where you can see these 10mm bolts right through these holes. Use a 10mm socket and extension and a ratchet. Remove these bolts.
When you have those bolts out you can move the window up and tilt it forward and lift it out all the way. Now you want to remove this bolt and loosen this one. Remove these two down here. Then remove these three here. This is your lead here for the window motor. Pull back on this tab and pull it up and out. Then pull this tab from the door. Fast-forward here again as I just remove those bolts that I pointed out to you. Once you have those off we'll feed this harness right through there, lift up on your motor, and then bring it out. Bring it over, bring it out, and then bring the assembly right out that way.
It's pretty straightforward. There are three screws. It does take some strength to get these loosened. I'll fast-forward here as I remove those three screws the rest of the way. Then make sure that you remove the little clip that clips the wiring harness to the motor bracket and remove the motor.
Take your motor and mount it to the new regulator. I apologize for the up-close shots of my forearm there. Motor down onto the regulator, flip it over. Start the three screws in and then tighten them up. Finish off by re-installing that clip into the motor bracket.
Make sure that you put this bolt back in to start it in up here. The motor regulator does go in now, right through, hang up there. Line up the motor here. Bring your harness through, like that. I'll fast-forward here. Just to summarize, you put the new regulator and motor in, you start that bolt in first and then you can hang the regulator rail up with that bolt. Then you hang the motor up with the tabs that are on the bracket. Then put all the bolts in by hand first and then tighten them up.
When you tighten them you want to tighten them nice and firm. Don't over-tighten them, though. Make sure it's in the back and in the front here. Lower it down slowly until you feel it come in contact with the regulator. Make sure it's positioned here, and then put these two bolts back in. On these bolts you'll kind of maybe just have to just grab the window, move it around a little bit, as you push in on the bolts and turn them clockwise to get them started. Then again, when you tighten these up you're going into a plastic fitting so don't over-tighten them or you'll strip the plastic.
With the key on you can see here that other than a weak battery that causes slow up movement, it's working well. I'm going to fast-forward through here as I put the door back together and get the water shield back up in place in preparation for putting the door panel back on. Put the panel back on. Just make sure that your harness comes up through. Lift it into the right place. Push against the window and down.
