Hi, I'm Mike Green. I'm one of the owners of 1A Auto. I want to help you save time and money repairing or 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 1AAuto.com. 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 remove and replace the rear power window motor on this 1997 Cadillac Deville. It's the same as any 1997 to 1999, similar for the 1994 to 1996. Except the door panel removal, it's a little different. The tools you'll need include a flat blade screwdriver, Phillips screwdriver, and a 10 mm socket and ratchet or wrench.

I recommend you disconnect your battery using an 8mm wrench, not totally necessary, but you will have your doors open for a while so it could run down your battery. First, you're going to carefully pry into the front here. There's a little tab in there that you want to push on. This comes up forward and up. You want to disconnect your cigarette lighter by pulling on these two tabs. There's a tab here, although this looks like it's broken. I'll remove that. Then you want to carefully tie the front of your light, here, back out. Then there's a little tab right here. Pry it with the screwdriver. That disconnects.

This, I'll pull down, up, and out. It should have a third clip. I think I may have forgotten it. Then, there's our lock switch here. Now, there are two Phillips screws, one here, and then one right in here. I'll fast-forward as I just remove those two Phillips screws. Then, up on the panel, and pull it out. Behind here is a little tab on your speaker. Disconnect the speaker. Pull the panel up and off. Pull down. There's your power window right here. There's a lead here. You can pry on it with a screwdriver. Pull it out.

These are 10mm bolts. There's three of them. We'll just fast-forward as we remove those three mounting bolts the 10 mm. They're actually nuts. The motor comes off. Replacing it, it's just simply bolting it back in.

The best technique for this is to put the motor on there and lightly bolt it on. Actually, put some tension into the bolts. If the motor goes right flush with the door panel, then you're all set. It may hang out about a quarter of an inch, which means it needs to mesh with the gear on the window. If that's the case, just tighten it up lightly. Then reconnect your battery, and run the window motor up and down. It will click, and then it will start moving the window. Then the gear is meshed, and then you can tighten up the bolts the rest of the way.

Now, reconnect your window motor. You can see, I've got the battery reconnected and I'm just testing it. The window moves up and down fine. Now, you can put out seal back up in place. Put our door panel back in place and connect our speaker again. These two go up through here and through there. Make sure this harness comes through here. Rotate the door panel back up. Make sure it's pushed on the door. Slide it down. Okay, we'll speed it up here as we put those Phillips screws in, and then tighten them up.
