Brought to you by, your source for quality replacement parts and the best service on the Internet. Hi, I'm Mike Green, I'm one of the owners of 1A Auto. I want to help you save time and money repairing and maintaining your vehicle. I'm going to use my 20 plus years' experience restoring and repairing cars and trucks like this, to show you the correct way to install parts from The right parts installed correctly that's going to save you time and money. Thank you and enjoy the video.

In this video we're going to show you how to replace the front power window regulator on this 2003 Buick LeSabre. Same as many GM full-size front-wheel drive cars, Bonneville, LeSabre, Park Avenue. Tools you will need are flat, Phillips screw drivers, as well as a 10mm socket and ratchet, and also a door panel clip tool or a putty knife.

You start with the flat plate screwdriver and this panel actually pulls, carefully, pry a little bit, up and out. Then there's a little wire for your speaker. Pry on the side where you can see the tab. Take the speaker lead up, okay, here pry at the front very lightly, pull that out, like that, and then again this little tab right here, pry that up, pull it out. Try not to drop that and then back here on your reflector, just going to pull in there and pry it out. Now inside the door, there are two screws, one there and one right there.

I'll just fast forward through removing those screws. They are Phillips screws. Use a putty knife or a door panel clip tool or whatever you might have, grab hold, use your foot a little bit. Give the door panel a good yank there. It comes up and off. Here there's a master switch. You pull out on a couple of tabs, so you pull out on these tabs and that rotates down so it comes out, and there's your door panel out. Pull our water shield back carefully. What I've done here is just to remove my harness from my door panel, plug it back in here. My regulator and window motor are fine, but most likely what you're going to see right here is you loosen this bolt, which undoes this pinch and you can slide the window up. If your regulator is broken, which happens most often with these cars, you'll be able to just slide your window up and down by hand to get to these. Actually, the best location is to bring your window all the way up, and you can access one of them right through here. Pull this little access plug off, and you can access the other one right through there. With the window all the way up, you can see there's one of them there and there's the other one there. You've just got to kind of push that cable out of the way. Right here is your window motor, the lead, just push down on this gray tab, shelve the screwdriver, and disconnect it.

Here with the window in the up position, I'm loosening those bolts that hold those pinch clamps that hold the regulator and the window together. I have my window motor unhooked from my regulator, which would be like having a broken regulator, and you can see I slide the window down, slide the regulator apart from the window and slide the window back up. Secure the window with a little bit of painter's tape to keep it from sliding down unexpectedly. A new regulator from 1A Auto, old regulator, you can see the new regulator from 1A Auto is exactly the same. It's going to bolt in and function and everything the exact same. The only minor difference is that it has a little bit of a lead on the window motor. I am going to re-install the original because on this vehicle the original is working fine and I don't believe in wasting a good part. Regulator in now you want to get this stud in place first.

Make sure that your regulator goes inside your window. Make sure that this part of your regulator goes inside your window. You can feel your glass here and we'll take it down. I'm just going to fast forward as I start those 10mm nuts, and then use my socket and ratchet to tighten them up. You want to tighten them up firm but not overly tight. Now I'm just taking the painter's tape off here. Slide the window down slowly, make sure it comes into our clips there and then what we can do is turn our key back on, run the window up in place, and then I'll tighten up our clamps. You want them to be firm. They don't have to be extremely tight. That's done. The window is going up and down nicely. Button our door back up here. Just to keep this video somewhat brief, I'm going to fast-forward through putting the door panel back on.
