Hi, I'm Don 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, I'm going to show you how to replace a rear window motor on this 2000 Nissan Altima, pretty much the same as any 1998 to '01 Altima. Usually you need to replace the motor when the window's not working and you press the switch and nothing happens. Tools you'll need are small flat blade screwdriver, a Phillips screwdriver, a 10mm socket with ratchet and extension, a putty knife or something similar to pry the door panel off, and you may need an impact driver. I show you how to use one in this video, although sometimes if you use a screwdriver and tap it with a hammer, that's good enough to get the screws that hold the motor loose.

Start by taking a flat blade screwdriver and there's a little trim button right down in here. You have to be careful, there's a little sticky stuff down in here sometimes, pry that up and then there's a Phillips screw there. Then here, you need to carefully, and you can see this is actually already been broken, but carefully go in here and pry out. Up here, pry out, and up here, pry out as well. Then remove this bezel. You can see it has four places where clips go in. Here I'm just using a Phillips screwdriver, take out that screw, and pull up on that pull cup. The pull cup comes up and off and the switch comes out with it; pull it backwards and out. Then underneath there's a tab on the harness where it connects, push the tab down, disconnect the harness.

I'm going to pull out, work your fingernails underneath, and pull out on the door panel and release a bunch of clips. Lift the panel up and off. Fast-forward here a little bit, there is a bracket on the middle of the door, use a 10mm socket and ratchet or a screwdriver would work and remove the bracket so that you can then pull that water shield down. You might be able to tell that somebody just cut the water shield before, that's not what you want to do, you want to pull it off, try not to damage it, keep it intact.

Now with that water shield out of the way, you'll see a brace that is held on by another four 10mm bolts. Remove those and remove the brace. Next there are six bolts that hold the regulator and motor assembly to the door. You'll see me removing those six bolts. You'll have to lift the window motor up a little bit and then down in, and you can see that the regulator and whole window assembly slides down a little bit. This allows you to get to the bolts that hold the window to the regulator. Here's a close-up. There's the kind of gold bolt right there and then there's one tucked in further. Here I'm using a 10mm wrench and kind of reaching in there and getting to that bolt that's kind of hidden in the door panel, and then I'll speed it up here as I remove that. Now, here I'm removing that other bolt that's fairly easy to get to, and once I get that out, then you're able to just grab hold of the window and lift it up. Just hold the window up with some painter's tape.

There's a little tab where you connect the harness. Pull that up and pull that off, and then you can just kind of reach in here and squeeze the two tabs for the motor harness. Bring the regulator and motor right out.

You may find you have to use an impact driver, what this is. You put it down into the screw and then you hit it, and it loosens the screw. Put it in the screw. You turn it counterclockwise. I'm just hitting it with the back of my hand. Yeah, it loosened the screw. Usually on these you can get them just by pressing really hard with a regular Phillips screwdriver.

Actually, first remove the clip for the harness, pull one side out, and carefully remove it. The motor, new motor from 1A Auto, put it on there. I'm going to fast forward as I put the screws back in and tighten them up with a screwdriver. Again, this is the part where, to get this apart, you may be able to be successful at getting it apart by using the screwdriver and just tapping it with a hammer as you try and loosen the screws. Usually it comes apart that way, rather than using the impact driver.


I've got my regulator-motor assembly back here, and I've actually hooked up the motor, and I've got my switch hooked up. What you'll want to do is carefully just run your regulator down a little bit, okay, and then put this bolt back up in here, and disconnect this again, and put the motor in and the regulator. The motor bracket hangs up there, and then, it comes down and hangs up right there. With the regulator, put that in. Then what you're going to do, is I'm going to bring the harness down, right out through here again. Reconnect them, and clip that on there. I still have the key on, I'm going to run this down until this hole lines up and I can see right through here. I'm going to fast forward again here as I disconnect the switch, and then I actually turn the key off on the car. Then I put all the bolts back in that hold the regulator rail and the motor bracket, and then tighten those up. Take the tape off, and you slide your window down, make sure it goes outside of the regulator. Then once the window's down, start the bolts in that hold the regulator to the window, and then tighten those up.

Now you're going to put the brace back on, it has an arrow that points up and it also has a Styrofoam block that goes in towards the inside of the door. Then use the four bolts to mount, tighten them up. Then put your water shield back up in place and the door panel brace back on.

To put this on, you want to get the back clipped in here first. I'm going to go at a pretty good angle, push it up, and then on. Now bring the front up, push it in towards the window and down on. Push the edges in. Put this back in place. Reach down in, grab the harness, and reconnect that. Push the front in first and then the back down in. We'll put our Phillips screw back in and then our little trim button.
