Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and the next time you need a part for your vehicle, think of Thanks.

In this video, we're going to show you how to replace the rear window regulator on this 2003 Nissan Altima. It's the same process on these Altima's from 2002 to 2006. We show you how to do this on the passenger side, but the driver side has the same process. This vehicle has a cable and rail style regulator, and these fail usually because of either a cable failing or the pulley breaks or something like that. To tell the sound of it failing there is usually a popping noise followed by a grinding noise. After you press the button to move the window, you'll hear the motor trying, but nothing's actually happening. This means the regulator has failed. You'll need a new rear window regulator from, a flat blade screwdriver, a Phillips screwdriver, and a 10mm socket and ratchet.

In your pull cap here, there's a small little screwdriver. Just pry that out and remove the Phillips screw that's under there. Now, carefully pry up your switch panel. Then disconnect the window switch by pushing on the tab on the harness. Behind your door handle, there's this little panel. You want to remove that, and then remove the Phillips screw in there, and then the one in this pull cap. Once those are removed just pull out along the edges of the door panel to separate the clips on the back. Then lift the door panel up and off.

On the back of the door panel are these two cables. You want to pull them out of the door, push them forward, and disconnect them. Remove your water shield carefully. You can see here, we're using utility knife to cut the adhesive. You can do that, or you just pull it carefully. You want to be careful not to stretch or rip the water shield too much. We do it so you have a better view of what we're doing inside the door. To remove the bolts and secure the window, you want the regulator to be down, and this is a cable cell regulator, so you should be able to just push the window down. If, for some reason, you can't, you should be able to access the two bolts with an open-end wrench. Those two bolts you can see they're right here, one here and one here, both of those are 10mm. Just go ahead and remove those, and once those bolts are removed you just lift your window and just tape it up.

To disconnect your power window motor, just push on the tab with the harness and pull up free. Then you want to remove the six bolts, each of them 10mm. Once those are removed, you can just pull your regulator down and out. On the left is the old window regulator; on the right is the new one from 1A Auto. You can see they're identical, and they'll mount up exactly the same. Take your regulator, you want to just replace that top bolt right there so that you can slide it into place, and just feed your regulator up into the door, and hang the regulator. Then we'll fast-forward as Don replaces the other five bolts. Reconnect the window motor harness, and now you can remove the tape from the window. Now, carefully lower the window down into the regulator, and you just want to make sure that the holes on the window are lined up with the holes on the regulator.

Replace those two 10mm bolts. Push your cables and harnesses back to that water shield, push it back up into place, and replace the bracket if you removed it. Now, to reconnect them, you want to clip them in, push them forward, and then push them back into the door. Now, put your door panel up on to the window cell and push it down, and then hit around the edges to reactivate those clips. Make sure your window switch harness comes through, and we'll fast-forward here as Don replaces the Phillips screw.

Then pull cap and Phillips screw behind the door handle and replace that little cover. Now reconnect your window switch, and push the switch panel down into place, replace that other Phillips screw, the pull cap, and the screw cover that goes over it, and you're all set.
